I see the the "Devices" tab has "USB Devices" and there it lists my USB drive, but it is gray and can not be selected. Perms on the device in /media are 0700 and it is owned by myuserid:myuserid
VirtualBox obviously is communicating with the device because it lists it as a "Sandisk MobileMate Reader". I have the latest Vbox (3.2.8) and have the 3.2.8 additions loaded as well. For what it's worth, CD/DVD and network devices work as expected with the XP virtual machine. The USB device is readable from Ubuntu (10.4 LTS) with no problems and is readable on non-virtual XP box. What am I missing here?
