Linksys WUSB 2.6 not working well?!

I have installed the atmel drivers for my Linksys WUSB 2.6 card in
Redhat 7.3 but I am consistently unable to connect to the Access Point
using the command:
iwconfig eth0 essid myessid

In dmesg:

hub.c: USB new device connect on bus1/1, assigned device number 3
