Previously working USB device no longer stays connected RRS feed

  • Question

  • I have a scanner that used to connect and appear as a COM port in device manager.

    Now, when I plug it in (Windows 10) my computer just keeps pinging. I opened USBDeview and can see it constantly trying to connect. The only thing that had changed, previously it was plugged into a hub and now its plugged into a hub chain...

    PC -> hub -> hub -> scanner

    All the other devices plugged into either hub still work, just the scanner has stopped.

    • I have tried unplugging all USB devices.
    • Connecting just the scanner.
    • Uninstalling, in device manager, everything under "Ports" and "Universal Serial Bus controllers".
    • Updating USB drivers.
    • Updating windows to latest.
    • Running drivecleanup (which uninstalls all unconnected devices and updates registry).
    • ...and restarting machine in between each step.

    Anyone got any other suggestions?
