Hello, I am totally new to linux, but pretty computer literate, so if someone could help me out I would appreciate it, thanks.

I have installed backtrack 3 on vmware workstation. I would like to install a linksys WUSB54G v2 wireless card on my gateway FX laptop because that linksys device supports packet injection. Backtrack doesnt automatically recognize the device so I need to install the driver, I have done some research and found I needed to install the driver RT61 and RT2500 chipset from this website........ cr.am browsing: http://www.ralinktech.com/ralink/Home/Support/Linux.html

However I have no idea how to install them from inside backtrack, so if someone knows please let me know.
thanks
