Hello,

 I have a dual monitor setup with 2 HP Compaq L2105tm touchscreens running on an HP EliteDesk 800 G2 TWR. W/Windows 7 Pro 64bit...The touchscreens work via a USB connection. All was working fine until recently when I unplugged the usb from the back of the monitors to clean them. Once I plugged them back in they would no longer function properly. Sometimes I can get one of them to work but only for a short time and if i leave them both plugged in the cursor will randomly start to move and click without any touch on the monitors happening. The driver is just a simple USB Optical TouchScreen Device. I have tried anything I can think of to get them to work again. Right down to using a different machine where they function just fine. So I feel like it's a driver issue. I've uninstalled/reinstalled the driver many times along with disabled then enabled them but nothing seems to work. I'm pulling my hair out and just don't know where to go next with it.

Have you tried uninstalling the device driver from Device Manager and selecting the 'Delete the driver software for this device' then restarting the computer before trying another install? 

 

Sometimes it helps.

Sometimes it helps.

If you disable the driver through the Device Manager and restart the computer Windows will find and install another driver.  If you have a driver which you can find at the product's website you can download it and then use the Device Manager under the Driver tab to use the Update  Driver.  This will give you the options to find another driver on your computer or go online to see if it can be found there.  Use the option to use a driver on this computer, you have the new driver already downloaded.


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
