Why hasn't anyone figured out a way to get the Linksys WUSB54G working. I believe it uses a PRISM54 chipset.... so obviously the ralink drivers will not work like they do on teh Version 4 which uses the ralink chipset

Obviously you are talking to Linksys WUSB54G v1 users and other people do not have this hardware.

I have WUSB54G v1 too. From linksys forum, v4 has ralink chipset and v1 has belkin chipset. Do you know belkin is the same as PRISM54?

I also need to find out the kext for my v1.

Nobody has figured it out yet because not enough people are interested.

jy371, Belkin is a company, not a chipset. Your question doesn't make a whole lot of sense. You need to figure out what chipset the card has.
