Weird: -22 is EINVAL.

I have attached a kernel patch you can use, which will catch the most 
obvious causes for this error to happen. Apply it, reboot into new 
kernel, and try again. Hopefully you'll see a new message just before 
the failed intr_urb.

This makes me suspect that you might be using the wrong WEP key or 
something like that. I just noticed that your earlier logs do not show 
any retry_failed interrupts -- unlike the problem I was comparing it to, 
where the device doesn't think it has transmitted anything and gives up 
retrying...

Anyway, hopefully we can fix the vendor driver, as this will give a 
clearer answer...
