I just picked up a Belkin USB wireless Adapter. I know that it is 802.11b and my access point is G, but after getting it to work on the PC I still can not get my PM7600 with USB card and 9.22 to work with it. I chose Belkin because it had 9.2 drivers online. Symtoms, The USB adapter is communicating through the USB port to the Mac or at least the Mac sees when it is not there. But the adapter doesn't even try to find the access point.
I think a friend of mine has a true 802.11b network, I think I will try connection there. Maybe if I force a mhz that might help?
