    Got a packard bell usb powered scanner when plugged into a new medion pc it does not work when plugged into my old compaq it does. Could there be a problem of not enough voltage going to the usb ports of the medion pc to power the scanner, is there anyway to check this without pysically using a meter on the usb terminals.

    I have one, it's basically a USB plug/wire attached to a 5V-rated LED. Simple to make, useful forever.

    Try using another port, if that doesnt work, do other USB devices work?

    make sure that the motherboard has the USB enabled in the BIOS and that you have the chipset USB drivers installed :D

    Seen this many a time. What u need is a POWERED usb hub, it's the same as a standard usb hub but connects to an AC adapter aswell so it'll provide the extra oomph for your scanner. They go for £10-£20 btw :)

    :EDIT: Make sure u check all drivers and software b4 u go spending any cash :EDIT:

    cheers guys
    all 4 ports failed to power scanner, but would power laptop hard drive and mouse so i guess it's a powered hub needed.
