In comment #7, I already gave the best debug log I could get:
Somehow, libusb-0_1-4-0.1.12-142.1.x86_64.rpm does not produce more logging
information than given there. Neither in combination with
libusb-1_0-0-1.0.2-2.2.x86_64.rpm (which is a non-debug-version afaik)
nor with
libusb-1_0-0-1.0.6-8.1.x86_64.rpm (which together with libusb-0_1-4-0.1.13
gave a reasonable error log)
I suspect that libusb-0_1-4-0.1.12-142.1.x86_64.rpm simply might not be a
(full) debugging version. BTW, I also tried
libusb-0_1-4-0.1.12-140.1.x86_64.rpm from
http://download.opensuse.org/repositories/hardware:/libusb0/openSUSE_11.2/x86_64/,
but I got the same poor logs.
I could not find a debugging version of libusb-1_0-0-1.0.2 anywhere.
If you could provide me with such a version, I will give it a try.
In that case, the scan stopped and reported I/O error. Only in the case
mentioned in comment #15, I finally had to stop with Ctrl-C (but a lot later
than the reported behaviour).

Still expecting debug logs from libusb0 done with the same scanner paramaters
as done with the unsuccessful scan.

When no data are read, some magic in the driver is applied. It probably
handles
the step back before continuing.
It happened at 21:45:30. Less than 2 seconds later scanner stopped to work.
Did you press Ctrl+C at 21:45:31 or only scanner stopped to work in this
moment?
In that case, the scan stopped and reported I/O error. Only in the case
mentioned in comment #15, I finally had to stop with Ctrl-C (but a lot later
than the reported behaviour).
