I have installed Win7 in a VirtualBox and am trying to install my Canon LBP-5050 printer. Trouble is, Win7 reports that the device has malfunctioned and was deactivated. On the same host, in a WinXP guest, the printer works. Also, on a Win8 laptop, it works. Is there anything with Win7 and USB in Virtualbox that I need to consider additionally? I tried a few other devices, e.g. a bluetooth stick and those worked.
