Re: kern/39211: ubsa device does no longer work since January 2008

[Matthias Drochner <M.Drochner%fz-juelich.de@localhost>]

You are right, the code was messed up when "uhmodem"
was added. Generally, if a USB driver attaches to an
interface, it is not allowed to set the configuration
later because this potentially invalidates all interfaces.
So ubsa should attach as whole device as it did before.
I'm not so sure about the config index. Your error message
suggests that your device supports only one configuration
and thus can only be set to index 0. But the code before
the uhmodem addition seems to use index 1...
(I've actually never seen a USB device with more than
a single configuration.)

Could you try the appended patch, as a starting point?

best regards
Matthias
