Re: SMC2662W V.4

Hi,

My friend finally got a chance to test it. At first we had some keyboard 
lockup problems when one plugged the device in, but that didn't seem to 
be related to this driver, more the usb system in the kernel. We worked 
around that by having the SMC2662W v4 plugged in at startup and it 
doesn't give us the keyboard lock then (that's a good enough work around 
for us). When we load the driver though, it still doesn't work. The 
dmesg results that apply are:

 From what I can tell, the "Bad board type set" error occurs when a 
board type is returned that is not any listed in this switch and case 
block, but BOARDTYPE_505_RFMD_2958 is listed there and defined as 7 in 
at76c503.h. So anyways this is a weird looking problem. Does anyone know 
what's going on?
