Finding the version number?

I bought the linksys wusb54gc, on the backtrack wiki is says the wusb54g V4, how can i tell wich version this is?

Look at the back of the unit. You may have to slide that mounting piece down to see it.

If you read the HCL Page here http://backtrack.offensive-security....nksys_WUSB54GC
the wusb54g is different than the Linksys WUSB54GC it says you need V4 for the wusb54g not the WUSB54GC

Just slow down and read.
