Re: USB/DVB - Old Technotrend TT-connect S-2400 regression tracked down

[David]

Again, hopefully with word wrap sorted out...

The device times out. Reverting b963801164618e25fbdc0cd452ce49c3628b46c8
causes it to work again

Reverting b963801164618e25fbdc0cd452ce49c3628b46c8 (manually, as there
are conflicting changes) causes it to work again. The wierd random
frontend number looks strange though.
