May I ask where did you get the 3.0.0.56 driver? I heard of the rumour of an update to the v 2.22 vendor driver a few weeks ago, but haven't seen it materialized yet. I'll be interested to have a look.
The rumour was from an Atheros guy (Atheros bought Zydas) on the linux-wireless mailing list. you may have better luck if you post there; but in any case I like to have a look at the 3.0.0.56 because I use/need AP mode. --- On Wed, 1/4/09, Amol Lad <amol....@gmail.com> wrote: > Hi, > > I am using an old USB 2.22 driver version on ARM based > platform and > 2.6.18 kernel.
