I2CHID Touchpad Device Driver Issue - Dell Latitude 3490

I may have a new and easy fix. I had the same issue on a Dell Vostro 5620. None of the above fixes worked and I made sure to update the firmware and reinstalled pertinent drivers. I'm not sure what got it to work, but I brought up the BIOS, verified that I had a cursor there, ran diagnstics (passed), booted to Windows and installed a USB-C wireless mouse as a work-around. At some point I removed the wireless mouse dongle and my trackpad cursor was back. It has remained through multiple restarts and shutdowns. My working theory is plugging in the dongle somehow fixed the issue.

I have found the true origin of my issue and managed to find a solution!

After finding the real issue, I managed to find the correct solution.

But first, make sure the Driver "I2C HID" is fully Updated (in my case it is v10.0.18362.1 provided by Microsoft. Kindly see the Driver Details given below) to see if fully updating fixes the issue.

WARNING: It's highly advised to make a backup of either the Registry Editor folder you plan on modifying or create a restore point for your whole computer. Information on how to do either can be found here: https://support.microsoft.com/en-us/help/322756/how-to-back-up-and-restore-the-registry-in-windows

----------------------------------------------------------------------------------------------------------------------

After you've ensured you're all backed up, you can continue. Follow the Below Steps below one-by-one carefully.

Step 1: Open Registry Editor with Windows + R and type "regedit"

Step: 2: navigate the folders to reach this point: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class

Step 3: Under the Class folder, you'll find a long list of keys. If you're issue is like mine and is related to only the touchpad, find and open 4D36E96F-E325-11CE-BFC1-08002BE10318 (take your time, make sure you don't modify the wrong folder)

Step 4: If you see the file "Upperfilters", delete it.

Step 5: Right click, select "new", select "New Multi-String Value" and name it "Upperfilters". You're essentially remaking the file you just deleted.

Step 6: Double click on the new "Upperfilters" value you just made.

Step 7: In the "Value Data" box, type "mouclass" and save.

You should now have a replacement file with the following information:

• Name: Upperfilters Type: REG_MULTI_SZ Data: mouclass

Step 8: Now restart your computer.

If it worked, nothing should be broken and your touchpad issues should be fixed! No more yellow triangle on the I2C HID Device!

Hi,

No matter perform driver update or uninstall it and reboot computer to load another driver, it will automatically check for driver from Microsoft driver store rather than load it from device manufacturer website. However, Microsoft driver store might have a delay for latest driver as it need to verified and validated by Microsoft.

I would recommend to download the latest driver from Dell website. Also enable "Do not include drivers with Windows Update" items through the following path:

Computer Configuration > Administrative Templates > Windows Components > Windows Update.

Bests,
