I'm completely new to this, but I've tried to search everything google, the search on this site, sun virtualbox forums, and I'm still clueless.
I've installed bt4 in vb and every time i try to enable my usb adapter WUSBS4GC I get

failed to atach usb device Cisco-linksys compact wireless-g USB adapter [0001] to the virtual machine Backtrack

Any pointers would be greatly appreciated.
I've been going crazy.
