Touchscreen stopped working + no HID in device manager + Unknown USB device

Hi,

My 7270 latitude touch screen stopped working shortly after first use (after win update worked again but for a short time).

All drivers are up to date.

In device manager a USB device shows as unknown (yellow warning triangle), otherwise there are no indications to the source of the problem.  There is no other touch screen device showing in device manager. 

How do I perminently solve this?

Thanks

I'm assuming windows 10 is on the system...

Please power off system, remove all peripherals such as printer, Scanner, Media Card Reader, Small Media cradles (iPod, PDA, MP3 player, etc.), Digital Cameras and Video Recorders, USB storage devices, and CDs or DVDs from all optical drives. Remove AC adapter, wait about 15 minutes,  and then power on system. Hopefully touchscreen work normally.

Hi,

15min power-off: (with nothing connected)

- This didn't fix the problem.

Updating driver :

- Windows has determined that the best driver is already installed.

Driver Date:  21-Jun-06

Driver Version: 10.0.15063.0

Device Status: Windows has stopped this device because it has reported problems. (Code 43)

                          A request for the USB device descriptor failed.

And again:  

- Along this report - the HID Touchscreen device is missing in the device manager.

- It seems that the system fails to properly recognize the HID Touchscreen drivers and catagorizes them as said problem.

I am searching for a solution to re-recognize the HID touchscreen drivers.

Thank you.

Found solution (Hope this is a permanent fix):

1. Go into Device Managaer  

2. Uninstall Unknown USB Device,

3. Click Scan for hardware changes.

Thats it - The system properly detects the drivers in HID, and touchscreen  works.

After you have run the System file checker:

Please type Troubleshoot Control Panel, click View All, and select Window Update troubleshooter. Run Hardware And Devices troubleshooter as well.

I'd suggest you download and run the free version of Malwarebytes - Official Site. The unknown USB device in device manager could be a nasty malware. If the Unknown USB device isn't a malware, I suspect the (Chipset) driver to be corrupt therefore, I suggest you run the System file checker. It scan for any corrupted system files that could be causing problems and fix those corrupt files as well.

a) Press Windows key + X key at the same time, select Command prompt (Admin)

b) In the command prompt type the following command: sfc/scannow and press enter

If no corrupted system files were found , then I would suggest you try the following steps:

a) Select Command prompt (Admin)

b) In command prompt, type the following commands and press Enter after each command....  

DISM.exe /Online /Cleanup-image /Scanhealth

DISM.exe /Online /Cleanup-image /Restorehealth

" All drivers are up to date "

I'm assuming you installed the latest BIOS version and Chipset drivers from your Dell Product Support page:

How to Find Drivers and Update Them (Official Dell Tech ...

And....

I'm also assuming you have the latest windows update which is the Creator Update.

Get the Windows 10 Creators Update - support.microsoft.com

Lastly,

If none of the troubleshooting steps fix the touch screen, I suggest .....

Refresh your copy of Windows 10 without losing your data

Or.....

Reset or reinstall Windows 10 - support.microsoft.com

" I am searching for a solution to re-recognize the HID touchscreen drivers "

In device manager, expand Human Interface Devices. At the  device manager taskbar, click Action, and then select Scan For Hardware Changes. Hopefully touchscreen driver appear. If the touchscreen still doesn't appears, click on View, and select Show Hidden Devices.

If touch screen driver still doesn't appear:

Run the System Restore Point tool to go back to an earlier time before touch screen start acting up - Type Create A Restore Point onto the search box, and then System Restore.

I have the same problem and I have already tried all those steps (I am an IT professional), plus I called the support and they tried the same steps again and again.
They told me to reinstall Windows, which I did, and now here I am with NO touchscreen and NO HID in device manager.
You Dell app is not finding any missing driver and Windows is up to date.
Now what?

Check for hidden devices and NTRIG drivers.

I have been searching high and low for a solution and this one did the trick.
