I cannot use a flashdrive in the Parallels partition (windows XP) of my mac book pro. The flash drive works on the mac side fine. I get this message:

USB device you are trying to connect to the virtual machine is being used by another process. Wait 5-10 seconds, then try to connect the device again. If this does not help, find the application that blocked up the device and disconnect it manually.

Following this advice does not remedy the problem at all. How can I get the flash drive to work on both sides: Mac and PC?

    When you remove the flash drive are you ejecting it or just unplugging it? If the latter then you need to use the system eject to remove it. You must also eject it properly from within Windows.

    It would help if you provided the version of OS X you are using in your configuration as well as more info on the hardware model and configuration. This information helps us know about your setup in order to provide assistance.

    Also, what version of Parallels are you using? Do you have USB support turned on in Parallels configuration? Have you searched the Parallels forum for possible solutions or posted your problem on their forum? This should be your first place to look for help, not the Apple Discussions.

    Make sure the flash drive is formated properly MS-DOS File System (FAT32). You then launch Parallels but don't start the virtual machine. From the Edit menu select Virtual Machine. Then add a USB controller. Select Connect to Macintosh. Then start the virtual machine. Window should now detect the new hardware and set it up properly. You can then access the flash drive.

    Also check that you have USB enabled in the Parallels Configuration Editor, and set Connection Options to 'Ask me what to do' in the same panel.
