I have been trying to get USB devices to work on my XP Guest for a couple days now without any success. The Host is Windows 7 and Guest is XP. I am using the PUEL VB Version. I have tried an open filter and specific filters for the devices but no difference. I cannot get any USB devices to connect to the guest except the USB Keyboard and USB Mouse which were automatically installed. I have tried several different flash drives and my Ipod Touch so far. When I plug in a flash drive with VB running the XP guest, the Host Windows 7 mounts the drive instead of the XP Guest. The VB USB status icon on the bottom right shows no USB devices attached. When I right click the icon, I see the flash drive "USB Mass Storage Device" State: Captured, when I click it I get the error message "Failed to attach the USB device Unknown device to the virtual machine Windows XP. "USB device 'USB mass Storage Device' with UUID {bla bla bla} is busy with a previous request. Please try again later."

Man I have been trying to get this to work for over a week/ Linux Host with Win 7. Everything works fine except the USB ports.
Hope someone gets an answer to this soon. Good luck.

I found the solution after installing VMWare Workstation for evaluation and discovered I had the same problem mounting USB devices with VMWare Workstation. The solution requires the removal of an "UpperFilters" entry in the Windows 7 registry. Removing this entry fixed both VMWare Workstation and VirtualBox USB functionality. Here is a link to the fix. http://mooremn.wordpress.com/2010/06/27 ... -disabled/
