Re: ASUS My Cinema-U3100Mini/DMB-TH (Legend Slilicon 8934)

[Alan Knowles <alan@akbkhome.com>]

Just a small update on this - I suspect ASUS released the wrong tarball 
for this device - as comparing the output from 'strings dib3000mc.ko' to 
the source code finds quite a few things missing..

Waiting on a response from ASUS now.
