Thanks! I was trying this step by step, but found some problems:

Just do a modprobe, without plugging the device, gives a backtrace on syslog:

modprobe r8192u-usb

Is this serious ?

Echoed the vendor/id values to /sys, and plugging the device gives:

Why does it rename wlan0 -> wlan1 ?
I have no other wifi device on this box, I am testing on my desktop instead
of the laptop the device was inteded for use...

Then I tried:

werewolf:/etc# iw info
nl80211 not found.
werewolf:/etc# iw list
nl80211 not found.

Looks like a module is missing....

This is kernel 2.6.37.

TIA
