6.2 -- Linksys wusb11 wireless supported?

[Jan Henrik Sylvester]

The only usb wlan driver in FreeBSD is ural (Ralink RT2500USB). Also, 
ndis (Windows driver wrapper) does not work for usb devices. Thus, you 
are out of luck.

(Some people seem to be working on porting rum and zyd from OpenBSD to 
FreeBSD, but that won't help you, either.)
