[sane-devel] HP ScanJet Pro 2000 sudden failure

[Ellis Cohen]

One more attempt:

I tried sending the entire output of 'lsusb -v' because I wasn't sure whether there might be interactions with different parts of the USB subsystem, that were contributing to the problem.

But in case it's sufficient to send only the immediately-local part of the output that deals with the HP ScanJet Pro, that part follows:
