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.
