Regression: USB/DVB 2.6.26.8 --> 2.6.27.6
I've just tried to upgrade my media server to the latest stable kernel and have found problems with my USB DVB devices. With the new kernel I'm seeing
DVB: registering new adapter (Technotrend TT-connect S-2400)
DVB: registering frontend 3 (Philips TDA10086 DVB-S)...
dvb-usb: recv bulk message failed: -110
ttusb2: there might have been an error during control message transfer. (rlen = 0, was 0)
dvb-usb: Technotrend TT-connect S-2400 successfully initialized and connected.
All of the registered DVB devices are now inoperable. dmesgs from both kernels attached. There are subtle differences in the device numbering as the devices were in warm state on the second kernel boot (however the problem is still present whether the devices are warm or cold).
Any help will be appreciated
Cheers

As another data point, I've just reproduced this on an x86-64 machine with just a single S-2400 using 2.6.28-rc5. The reply message seems to timeout.
