  • Touchscreen hibernate help

    I have a Xenarc 700TSV with serial touchscreen. I use a usb-to-serial adapter to connect the serial ts to the usb hub near the dash. When resuming from hibernate, the touchscreen does not work. If I launch the configure utility, after a short delay the ts starts working again.

    Any ideas on what the problem is or how to automatically get the touchscreen working after hibernate?

      Reply this might help but not sure. Assuming its the same on any Windows if you have USB ports. (I have XP)
      Go to Control Panel-->System-->Device Manager

      Click on Universal Serial Bus Controllers and for example mine says:

      Generic USB Hub
      Intel (blah,blah,blah) Host controller 2442
      Intel (blah,blah,blah) Host controller 2444
      USB Root Hub
      USB Root Hub

      Click properties on the bottom two
      Click Power Management
      Uncheck Allow Computer to turn off this device to save power

      Might Work might not haven't really tested it but it seems plausible that would make the USB always powered.
