In the meantime I've done a lot of bisection and inserting printk's
(needs a reboot every time, that's why I didn't react yet).

I think I can tell even a bit more than this patch will. I already found
out that the device appears to have no data connection but does have a
control connection. The lack of data connection seems to yield the NULL.
I will now test with data_connection forced to be equal to
control_connection, because apparently some devices actually work with
only connection, maybe this is one of them.

Will have more details later.

Thank you for your interest.
