usb 1-2: USB disconnect, device number 10Īt more or less regular intervals, the screen disconnects, only to be recognised as a new device about five seconds later, with its device number one higher than before repeat. usb 1-2: new full-speed USB device number 10 using xhci_hcd usb 1-2: USB disconnect, device number 9 usb 1-2: new full-speed USB device number 9 using xhci_hcd usb 1-2: USB disconnect, device number 8 usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-2: New USB device found, idVendor=1870, idProduct=0001 Here’s (some of) the relevant output from dmesg: usb 1-2: new full-speed USB device number 8 using xhci_hcd Then I did some more digging, and found that the screen keeps disconnecting. I had to plug in PS/2 mouse and keyboard to be able to uninstall the driver, after which things luckily were back to where I was before. The computer ran fine, but touchscreen, mouse and keyboard were all non-functional. No such luck: instead, all USB devices stopped working. The manufacturer’s web site does have Linux drivers for it, but those are almost a decade old as well since Mint is Ubuntu-based, I decided to try the Ubuntu 10.10 drivers just in case they would get the screen to work. When I plug it into the computer, it fails to work - tapping the screen produces no response. Unfortunately, the screen is old (about ten years) and made by a company that seems to have liked rolling their own. I’ve got a computer running Linux Mint 19.1 that needs to have a touchscreen hooked up to it.
