Just confirm that I have the same problem (with a WUSB11 V2.8) that the driver can't transmit when in Ad-Hoc.
Turning on debug with 'iwpriv wlan0 set_debug 180' shows that it's receiving however the TX data doesn't show up (as it does in Managed mode). TX counter in 'ifconfig' doesn't increase either.

I did find that the driver at http:// at76c503a. berlios. de/ seems to work better.
I'll try to check the patch out,
