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

[David]

I reported this DVB-S card breaking between 2.6.26 and 2.6.27. I've
finally had time to do some digging, and the regression is caused by:

    b963801164618e25fbdc0cd452ce49c3628b46c8 USB: ehci-hcd unlink speedups

..that was introduced in 2.6.27. Reverting this change in 2.6.29-rc5
makes the card work happily again.

I don't know enough about USB protocols to speculate on whether there
may be a better fix, but hopefully someone cleverer than me can get to
the bottom of the problem?

Cheers
David
