Hi,
I got Sharp Zaurus SL-5000D(Linux PDA), and try to connect
via docking station. It is USB Ether devices but it doesn't
be recognized by linux-2.4.17 kernel.
I'm not sure how to fix is correct. Anyway, this docking station says
it has bInterface Class:SubClass:Protocol = 02:06:00 with bNumEndpoints = 00,
so with the following patch, it works fine for me.
Thanks,
