Hi,

PCI\VEN_8086&DEV_7360&SUBSYS_00208086&REV_01

My device is a Dell Latitude 5340 and I cant seem to find the proper driver.

Most likely that PCI ID belongs to an Intel chipset‑related device (on Latitudes like yours it’s usually Thunderbolt/USB4, Serial IO, or a similar Intel controller) that just doesn’t have its specific Dell driver installed yet.

You can usually fix it by installing a couple of key drivers from Dell’s site, even if SupportAssist says everything is fine.

1. Confirm the hardware ID

You already have the main ID, but just to be sure:

• Right‑click Start → Device Manager.
• Find the unknown device (yellow exclamation mark) → right‑click → Properties.
• Go to the Details tab.
• From the Property dropdown choose Hardware Ids.
• Copy all the lines shown (there are usually several: PCI\VEN_8086&DEV_7360&… etc.).

If you post the full list of Hardware IDs in your thread, other members can try to match it exactly in PCI ID databases.

2. Try the most likely Dell drivers (Latitude 5340)

Go to Dell’s Drivers & Downloads page for the Latitude 5340, make sure the correct OS is selected (Windows 10/11 64‑bit), then under Chipset download and install, in this order:

• Intel Chipset Device Software (or “Intel Chipset Driver”)
• Intel Serial IO Driver (often fixes “Unknown PCI device” entries)
• Intel Management Engine Components (MEI)
• Intel Thunderbolt Controller / Intel USB4 Host Router / Thunderbolt Driver (if your 5340 has Thunderbolt/USB‑C with TB support)

After each one (or after all), reboot and check Device Manager to see if the unknown PCI device disappears.

3. Use Intel’s own driver tool

To catch something Dell might not be flagging:

• Install Intel Driver & Support Assistant (Intel DSA) from Intel’s official site.
• Run a scan and install any chipset / Thunderbolt / Serial IO drivers it suggests.
• Reboot and re‑check Device Manager.

4. Windows Update – optional drivers

• Go to Settings → Windows Update → Advanced options → Optional updates.
• Check Driver updates and install anything that looks related to Intel chipset / system / Thunderbolt.

5. If it’s still there

If the device is still showing as unknown after installing:

• Intel Chipset Device Software
• Intel Serial IO
• Intel Management Engine
• Intel Thunderbolt/USB4 driver (if applicable)

then:

• Post a screenshot of the Device Manager entry.
• Post all of the Hardware IDs from the Details → Hardware Ids list.

With that, it should be possible for forum members to pinpoint the exact component (e.g. specific Thunderbolt, GPIO, or another Intel controller) and link the exact Dell or Intel package you need.

Summary
The ID PCI\VEN_8086&DEV_7360 is an Intel device, and on a Latitude 5340 it’s almost certainly a missing Intel chipset‑related driver (often Serial IO or Thunderbolt/USB4). Install the Intel chipset, Serial IO, ME, and Thunderbolt/USB4 drivers from Dell’s 5340 driver page, then check again. If it’s still unknown, share the full hardware IDs so it can be identified precisely.

Those two entries (PCI Serial Port + PCI Simple Communications Controller) on a Latitude like yours are almost always the Intel Management Engine / AMT (vPro) related drivers that are missing – not anything “dangerous”.

To be sure and to fix it, do this:

1. Confirm the Hardware IDs

For each of the two devices:

• Right‑click PCI Serial Port → Properties.
• Go to the Details tab.
• From the Property drop‑down, choose Hardware Ids.
• Copy all lines you see there and paste them here.
• Repeat the same for PCI Simple Communications Controller.

That will let us match them exactly to the Intel component.

2. Most likely fix on a Dell Latitude 5340

On Dell’s driver page for the Latitude 5340 (with your correct OS selected):

• Look under Chipset or Security / System Management for entries like:
  • Intel Management Engine Components Installer (or “Intel Management Engine Interface” / “MEI”)
  • Intel AMT / Intel Active Management Technology driver (often includes Serial Over LAN (SOL) / Local Manageability Service)
• Download and install the Intel Management Engine package first.
• Reboot.
• Then install any Intel AMT / SOL / LMS package you see.
• Reboot again and check Device Manager.

Typically:

• PCI Simple Communications Controller → fixed by Intel Management Engine Interface driver.
• PCI Serial Port → fixed by Intel AMT / Serial Over LAN driver.

3. If Dell doesn’t show anything

Sometimes Dell’s site/SupportAssist doesn’t list these if AMT/vPro is disabled or considered “optional”.

You can try:

• Install Intel Driver & Support Assistant from Intel’s official site.
• Run a scan and install any Management Engine / AMT / Serial Over LAN drivers it offers.

4. If you don’t need AMT/vPro

If this is your personal machine and you never use remote management:

• Enter the BIOS (press F2 at boot on Dell).
• Look for settings like Intel AMT / vPro / Intel Serial Port / SOL.
• Disable AMT / SOL there.

Once disabled in BIOS, those devices usually disappear from Windows entirely (no more yellow exclamation marks).

Next step
Please post the full Hardware Ids for both devices. With those, it’s possible to say exactly which Intel package you need and, if necessary, point you to the right category on Dell’s site.

PCI\VEN_8086&DEV_7360&SUBSYS_00208086&REV_01
PCI\VEN_8086&DEV_7360&SUBSYS_00208086
PCI\VEN_8086&DEV_7360&CC_0D4000
PCI\VEN_8086&DEV_7360&CC_0D40

Those IDs help narrow it down: it’s clearly an Intel device (VEN_8086) and the class code CC_0D40 puts it in the wireless / special controller category – on a Latitude 5340 that’s very likely the Thunderbolt/USB4 controller (or a closely related Intel chipset function), not something like MEI/AMT.

I can’t say 100% which exact Intel chip it is, but on that model the missing driver is almost always a Thunderbolt / USB4 or Serial IO / chipset package.

1. Try the Dell Thunderbolt / USB4 driver first

On Dell’s support page for the Latitude 5340:

• Select your exact OS (e.g. Windows 11 64‑bit).
• Under Chipset and/or Docks / Stands look for entries named something like:
  • Intel Thunderbolt Controller Driver
  • Intel Thunderbolt 4 / USB4 Host Router Driver
  • Sometimes bundled as Intel Thunderbolt Controller Firmware and Driver
• Download and install that package.
• Reboot and check Device Manager to see if the 8086:7360 entry disappears.

2. Then install the remaining chipset‑related drivers

Still on the same Dell page, with your OS selected, install:

• Intel Chipset Device Software (Chipset)
• Intel Serial IO driver (Chipset)
• Intel Management Engine Components / Intel MEI (Chipset or Security/System Management)

Reboot after these and verify if the unknown PCI device is gone.

3. Use Intel Driver & Support Assistant (as a cross‑check)

If Dell’s packages don’t clear it:

• Download Intel Driver & Support Assistant (Intel DSA) from Intel’s official site.
• Run a scan.
• Install anything it offers related to:
  • Thunderbolt / USB4
  • Chipset / System
  • Serial IO
• Reboot and re‑check Device Manager.

4. If it’s still unknown

If after all of that the 8086:7360 device is still listed:

• Post a screenshot of how it appears in Device Manager (the category + device name).
• Also open its Properties → Details → Property = Compatible Ids and copy those too.

With that extra info, it should be possible for forum members to match it more precisely (e.g. to a specific Thunderbolt/USB4 or other Intel controller) and point to the exact Dell/Intel package.

Summary
The ID PCI\VEN_8086&DEV_7360&CC_0D40 is an Intel controller in the wireless/special‑controller class, and on a Latitude 5340 it’s very likely the Thunderbolt/USB4 controller or a related chipset function. Start by installing Dell’s Thunderbolt/USB4 driver, then the remaining chipset/Serial IO/MEI packages.

Some users say that the provided Hardware IDs are related to Intel XMM 7360, but I cannot seem to find a driver for it on my Dell suppot

You’re right: PCI\VEN_8086&DEV_7360 matches the Intel XMM 7360 LTE‑Advanced modem (WWAN card).
On a Latitude 5340 this is an optional 4G/LTE module, so Dell only provides a driver if the machine was shipped with that option and usually lists it under Network drivers, sometimes only for Windows 10.

Because I can’t see your exact service tag, I can’t point to a specific download, but you can try the following.

1. Check whether your 5340 actually shipped with WWAN

• On Dell’s site, enter your Service Tag → open Original Configuration.
• Look for entries like “Intel XMM 7360 LTE‑Advanced” or “WWAN / LTE / Mobile Broadband”.

If there is no WWAN/LTE module listed, Windows is probably seeing a leftover device entry or hardware that isn’t meant to be used; in that case you can safely disable it (see step 4).

2. Look for the WWAN driver on Dell’s site

Still on the Dell support page for your Latitude 5340:

• Set OS to Windows 10 64‑bit (even if you run Windows 11 – WWAN drivers are often only listed under Win10).
• Filter by Network.
• Look for anything mentioning:
  • “Intel XMM 7360”
  • “Intel LTE‑Advanced”
  • “Mobile Broadband”, “WWAN”
• Download and install that package, then reboot.

These drivers are usually generic enough to work on Windows 11, even if Dell doesn’t mark them as such.

3. If your tag shows WWAN but no driver appears

WWAN drivers are sometimes shared across similar Latitude models.

You can:

• Search Dell Support (global) for "XMM 7360 LTE Advanced driver".
• Or check drivers for a close model that officially shipped with that modem (for example, other Latitude 53xx/54xx models).
• Download the WWAN/LTE/XMM 7360 driver from there and try installing it on your 5340.

This usually works, but it’s technically “use at your own risk”, so create a restore point first.

4. If you don’t use LTE at all

If you never use a SIM card / mobile broadband, the easiest solution is just to disable the device:

• In BIOS: press F2 at boot → look under Wireless or Communication and disable WWAN / Mobile Broadband, then save and exit.
• Or in Windows: right‑click the device in Device Manager → Disable device.

This won’t affect Wi‑Fi or Ethernet; it only turns off the cellular modem.

5. If you’re still stuck

Because I can’t see Dell’s page for your exact tag, if:

• Your original configuration does list an Intel XMM 7360 / LTE module, and
• You don’t see any WWAN/LTE/XMM driver under Network for any OS,

then it’s worth posting that info (plus your OS version) in your thread. Another member might have the same 5340 configuration and can link the exact driver they used. If necessary, you can also contact Dell Support directly and ask for the WWAN/XMM 7360 package for your service tag.

Summary
Yes, your hardware IDs point to the Intel XMM 7360 LTE‑A modem. If you use LTE, you’ll need the WWAN/LTE/XMM driver from Dell (often only visible under Windows 10 and under the Network category, or from a closely related Latitude model). If you don’t use LTE at all, the simplest fix is just to disable WWAN in BIOS or Device Manager and ignore the missing‑driver warning.

I booted into bios and checked everything in the "Integrated Devices" and I could not see anything related to LTE or Mobile Broadband, so it seems my system is not equipped with one. But if it is not equipped with one, why does it show as missing in the Device Manager?

I booted into bios and checked everything in the "Integrated Devices" and I could not see anything related to LTE or Mobile Broadband, so it seems my system is not equipped with one. But if it is not equipped with one, why does it show as missing in the Device Manager?

Windows only shows a device in Device Manager if the firmware/BIOS tells it “this PCI device exists”.
So if you see PCI\VEN_8086&DEV_7360, the platform is exposing an Intel XMM 7360 function to the OS, even if you don’t actually use LTE.

On Latitudes this can happen for a few reasons:

• Dell uses one mainboard design for many configs. The XMM 7360 modem may be soldered or present electrically, but your system is sold as “no WWAN” (no antennas, no SIM slot, not enabled in sales config).
• The BIOS sometimes doesn’t fully hide the WWAN PCI function when WWAN is “not configured”, so Windows still enumerates it as hardware – but Dell doesn’t bother to list a driver for systems that weren’t ordered with WWAN.
• Less common: it’s a leftover/phantom device entry from an image that had WWAN support, but the hardware isn’t actually used.

So: it shows up because the hardware (or at least the PCI function) is present enough for Windows to see, but Dell doesn’t treat it as an officially supported option for your exact configuration.

You have two practical options:

1. Confirm your factory config

• On Dell’s site, enter your Service Tag.
• Open Original Configuration and check if anything like “Intel XMM 7360 LTE‑Advanced / WWAN / Mobile Broadband” is listed.

If there is no such entry, Dell sold it as a non‑WWAN system. The device is just an unused/unsupported function.

2. Disable it so it stops bothering you

If you don’t need LTE (and it sounds like you don’t):

• In Device Manager, right‑click the device → Disable device.
• Optionally: View → Show hidden devices, right‑click it → Uninstall device (don’t worry, if the firmware really wants it there, it will just reappear as disabled after a reboot).

This is safe and won’t affect Wi‑Fi or Ethernet; it only hides an unused modem function.

If you actually want LTE

If your “Original Configuration” does show an XMM 7360/WWAN option, then Dell should provide you with a driver even if it isn’t visible on the support page. In that case I’d suggest:

• Contact Dell Support with your service tag and ask specifically for the Intel XMM 7360 / WWAN driver.

Bottom line
It shows in Device Manager because the motherboard exposes that Intel modem function even on non‑LTE configs. If you don’t use mobile broadband, simply disabling the device in Windows is perfectly fine and often the only realistic “fix.”

Querying Dell service tag will give you an idea of the components inside.

Another way is try using Iobit Driver Booster. Install and scan and it will show you the recommended drivers.

Using the service tag is definitely the right, “clean” way to see what the machine actually shipped with. If the original config doesn’t list WWAN / LTE / XMM 7360, then Windows is just seeing an unused PCI function and you can safely leave it disabled.

About IObit Driver Booster:

• Tools like this can sometimes find drivers that OEM sites don’t show, but
• they also have a history of:
  • Installing non‑OEM / generic drivers that break things (BSODs, lost audio, lost touchpad etc.).
  • Bundling extra software or showing aggressive ads/“cleaner” offers.
  • Offering “newer” drivers that the OEM has intentionally not validated for your model.

For drivers – especially on a business notebook like a Latitude – it’s usually safer to stick to:

• Dell Support site with your service tag (chipset, ME, Serial IO, Thunderbolt, etc.).
• Intel Driver & Support Assistant for Intel‑branded components.
• Windows Update → Optional updates for Microsoft‑provided drivers.

If someone still wants to use Driver Booster or similar:

• Use it only to identify hardware, not to mass‑update everything.
• Create a System Restore point first.
• Install one driver at a time and test, instead of letting it auto‑update dozens of drivers.

In your specific case, since you don’t have LTE hardware configured and don’t plan to use it, the safest and simplest option remains:

• Just disable the XMM 7360 device in Device Manager and ignore it.

Microsoft Update Catalog

Microsoft Update Catalog

www.catalog.update.microsoft.com

That Microsoft Update Catalog search is exactly for your hardware ID, so those packages are Intel XMM 7360 drivers published via Windows Update.

If you want the modem working (and are OK using a generic Microsoft‑supplied driver instead of a Dell one), you can install from there; just do it carefully.

1. Which entry should you pick?

On that page, look for an entry that:

• Mentions Intel XMM 7360 or similar in the description.
• Matches your OS (e.g. Windows 10 64‑bit or Windows 11 64‑bit).
• Is the newest version for your OS (check the Last Updated and Version columns).

I can’t see your exact OS version or the catalog list from here, so I can’t safely say “download file X”, but the above is how to choose.

2. How to install a driver from the Update Catalog (.cab)

Once you’ve picked the right one for your OS:

1. Click Download on the chosen entry in the Update Catalog.
2. A small window with a .cab URL appears → click it to save the .cab file.
3. Create a folder, e.g. C:\Drivers\XMM7360.
4. Right‑click the .cab → Extract all… → extract into that folder
   (or use `expand file.cab -F:* C:\Drivers\XMM7360` from Command Prompt).
5. Open Device Manager → right‑click your Unknown device / XMM 7360 → Update driver.
6. Choose Browse my computer for drivers.
7. Browse to C:\Drivers\XMM7360 (the folder you extracted to) → Next.
8. If the package matches, Windows should find the INF and install the driver.
9. Reboot and check if the yellow exclamation mark is gone.

3. Risks / things to keep in mind

• These are generic drivers distributed by Microsoft, not specifically tested by Dell for your Latitude 5340.
• They usually work fine, but there’s always a chance of:
  • No signal / no SIM detection
  • Occasional disconnects or power‑management quirks
• Before installing, you can create a System Restore point, so you can roll back if anything misbehaves.
• If the driver installs but you never use LTE anyway, it only removes the warning symbol; it won’t give you extra benefit.

4. If you don’t actually need LTE

Nothing wrong with trying the Microsoft driver, but the simplest and safest option is still:

• Right‑click the device in Device Manager → Disable device.

That avoids any risk from extra drivers and keeps Wi‑Fi/Ethernet unaffected.

Summary
Yes, that Microsoft Update Catalog page contains official drivers for your exact hardware ID. Pick the entry for your OS, extract the .cab, and point Device Manager to the extracted folder. If you don’t care about LTE and just don’t want warnings, disabling the device is still the easiest route.

I have Dell Support assistant installed and it did not find a driver.


As for using Driver utilities, they caused issues for me in the past so I'm not risking it, but thank you for the suggestion.

That makes perfect sense – if driver utilities have caused issues for you before, it’s smart to avoid them.

Why SupportAssist didn’t find anything
Dell SupportAssist usually only offers drivers that match your factory configuration. If your service tag doesn’t list WWAN / LTE / Intel XMM 7360 in the Original Configuration, Dell often won’t:

• Expose a WWAN driver for your tag
• Or flag it as “missing” in SupportAssist

So SupportAssist finding nothing for that device is consistent with “this system was sold as non‑WWAN, even though the PCI function is visible.”

Your safest options (without driver utilities)

• If you don’t care about LTE at all (no SIM, no mobile broadband use):
  • In Device Manager, right‑click the Intel XMM 7360 / Unknown device → Disable device.
  • That’s it. It won’t affect Wi‑Fi or Ethernet, and you avoid installing any extra drivers.
• If you’d like to clear the warning and maybe use LTE, but still avoid utilities:
  • Use the Microsoft Update Catalog link you found (for your exact HW ID).
  • Download the correct entry for your OS, extract the .cab, then in Device Manager use:
    • Update driver → Browse my computer → point to the extracted folder.
  • Create a restore point beforehand so you can roll back if needed.

Given your past issues with driver tools, simply disabling the device is a perfectly reasonable and low‑risk solution here.

That entry you found is this one (in French):

“Micrologiciel Dell Wireless 5823e et Intel L860‑R LTE et pilote GNSS”
Category: Modem/Communications – and it’s marked as Recommandé.

What it is
That package is the firmware + driver for Dell’s WWAN module (Dell Wireless 5823e, based on an Intel LTE modem – L860‑R, plus GNSS). In other words: it’s the mobile‑broadband/LTE card driver.

Given your earlier hardware IDs and the fact that this is:

• From Dell’s site for the Latitude 13 5340 2‑in‑1
• In the Modem/Communications category
• Flagged as Recommended for your system

this is the most likely OEM‑correct driver for the unknown “Intel LTE” device you’re seeing in Device Manager.

Even though the BIOS didn’t show a clear “WWAN” toggle, it’s still common that:

• The PCI function for the LTE modem is exposed to Windows
• But the BIOS menu doesn’t show a separate WWAN option, or only shows it when certain configs are present

So BIOS not listing WWAN doesn’t necessarily mean the modem/PCI function isn’t there.

What I’d do in your place

Since you prefer to avoid driver utilities (which is reasonable) but are OK with OEM drivers:

1. Download that “Dell Wireless 5823e and Intel L860‑R LTE and GNSS driver/firmware” package from the Dell page.
2. Run the installer normally and let it complete.
3. Reboot.
4. Open Device Manager and check whether:
   • The yellow‑marked “Unknown device” (with the 8086:7360 ID) is gone, and
   • You now see something like “Dell Wireless 5823e / Intel L860‑R LTE” under Network adapters or Modems.

Because this is a Dell‑signed, model‑specific package, it’s safer than using generic tools or random driver packs.

If it doesn’t install or nothing changes

• If the installer says something like “no compatible hardware found”, then your specific unit probably doesn’t have that WWAN module despite Dell listing the driver for the model series.
• In that case, you can simply:
  • Right‑click the unknown device in Device Manager → Disable device.
• If it does install but you don’t care about LTE at all (no SIM use, etc.), leaving the driver there is harmless; it just makes the warning disappear.

Bottom line
That Dell “Wireless 5823e / Intel L860‑R LTE” package is very likely the intended WWAN/LTE driver for the PCI device you’re seeing. It’s safe to try installing it; if it doesn’t detect hardware, just disable the unknown device in Device Manager and you’re done.

If everything is working fine I wouldn't worry about it, I rarely mess with drivers.

If everything is working fine I wouldn't worry about it, I rarely mess with drivers.

That’s a perfectly reasonable stance, especially on a business laptop like a Latitude.

Given your situation:

• You don’t use LTE / mobile broadband.
• Windows and all your actual networking (Wi‑Fi, Ethernet) work fine.
• The only “issue” is a yellow exclamation mark for a WWAN/LTE device.

Then you really have only two practical options, both safe:

• Do nothing – leave it as‑is. A missing driver for unused LTE hardware won’t hurt performance or stability.
• Disable it in Device Manager if the warning bothers you:
  • Right‑click the device → Disable device.

Installing the Dell LTE driver you found is also fine if you want a completely “clean” Device Manager, but it’s optional. There’s no need to keep experimenting with drivers as long as everything you actually use is working correctly.

In short: if the system is stable and you don’t need LTE, it’s absolutely OK to leave this alone or simply disable the device and move on.
