Anyone having a problem with a scanner showing up as Unknown in Device Manager?

    Question

  • My scanner (a new CanoScan 5600F) appears as Unknown in the Device Manager. I've downloaded and installed (several times) the latest driver from Canon. Also:
    • I've tried the scanner on two PCs running XP Home--a new Compaq Presario and a new VisonMan barebones. It doesn't work on either one.
    • I've also tried Epson scanners on these two machines, and they don't work either.
    • However, when I run the Compaq Presario with Vista (which came with it), the Canon scanner works. Problem is, I'm not using Vista (or Win7) and have no plans to.
    This would seem to imply that it's a problem with XP Home not recognizing the scanner. I haven't had this problem with any other USB device. Any suggestions?

    Thanks.
