    USB Flash Drives not recognized/accessed by virtual machine
    I'm using an early version of Parallels installed when I purchased my Mac Book 2 years ago. I use Intuit Quicken software on a PC desk top and back up data to a Cruzer Flash drive. When I use the Quicken software on my virtual machine I attempt to restore using the updated data on the flash drive. Is recognizes the flash drive as inserted but I always get a message stating that the USB device I am trying to access is being used by another process and that I should terminate that process then reattempt. I am UNABLE to determine what, if any, process is using the USB device (Flash Drive) If anyone could tell me how to overcome this I would be very grateful.

    The first thing to try is another flash drive. (They're inexpensive.) If no joy there, upgrade Parallels to the latest version and make sure the guest tools are installed.

    When you start the virtual machine, are you resuming it from a paused state, or do you do a full boot up?
    Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!
