i tried installing the windows drivers of the device in backtrack, they were installed and a icon was formed on my desktop in bt4 but when i connect the device the aplication tells "no device" i guess its not reading it right? so tell me wat to do now.
Boot linux, and run lsusb and it gives you an ID number for each device, e.g.
Bus 002 Device 002: ID 1241:1166 Belkin MI-2150 Trust Mouse
google for the ID number; in the example above that's 1241:1166
See what you can find.
