I believe that recompile uas.ko module is a too hard task for me: some
years ago I usually recompile kernel on RedHat distribution, but there
was a srpm package and a simple rpm --rebuild command solved. Now I'm
using a Ubuntu distribution and I believe that recompile a ppa version
of kernel is a "bit" hard.
If I found a simple way to obtain a uas.ka module I'll try your patch.
Regards,
Claudio
