Can anybody help?

[Mayur Shah]

 I am using the hostap drivers with gumstix product. www.gumstix.com
for compact flash NETGEAR card MA70.

My objective is to connect wirelessly from this embedded device.
When I try to run any any iwconfig command for example,

 iwconfig wifi0 essid xyz

 I get this error
 Error for wirreless requuest "Set ESSID " (8B1A) :
 SET Failed on device wifi0: Invalid Argument

 And this is the same error I get for any type of iwconfig command.
Also in most of the documentation I read, I found the interface to use
is wlan0 but what i get when i do iwconfig is usb0 and wifi0 intefaces
only.

 Can you tell me where the problem is ,

 * Do I need to download new "iwconfig"?
 * Do I need some drivers for hostap

 This gumstix stuff used linux kernel 2.6.10

 Thanks & Appreciate your help
