Yep - I see ... you haven`t got another linux box around (with a distro actually

it would be easier to debug this if you could move the controller to another
box and actually fiddle with the driver source ... debug printks can actually be
useful :)

As I said - it would be useful if you could actually put the controller
in a box _with_ a distro already installed :)
