I tried to fix my settings and will test it by sending a patch to myself
using git send-email.

Where can I find a list of IDs?
I can't find much information on a gene1270 board in
arch/arm/tools/mach-types.
Is a MACH_TYPE identifier mandatory?

Thanks. Set to 0x4000.

I need some HW address and USB VID:PID to get it working.
TI's code does it and so does siemens' rut.
I could drop this functionality and remove it all.
