[STR New]
I have applied this patch and the patch of STR #3965 to the package in
Ubuntu Oneiric now and asked the people suffering the following Ubuntu
bugs for testing:
https://bugs.launchpad.net/ubuntu/+source/cups/+bug/887094
usb printer backend crashes
https://bugs.launchpad.net/ubuntu/+source/cups/+bug/872483
laser printer only prints first job correct
https://bugs.launchpad.net/ubuntu/+source/cups/+bug/883169
Brother MFC-8840D usb printer not detected
https://bugs.launchpad.net/ubuntu/+source/cups/+bug/793244
After suspend/hibernate usb printer backend repeatedly crashes
https://bugs.launchpad.net/ubuntu/+source/cups/+bug/564917
Ubuntu 10.04 does not recognize local printer connected via
USB/parallel adapter cable
For the first three I got answers and they are definitely fixed by the two
patches. On the other two I am still waiting for an answer but they are
most probably also fixed.
Together with the USB fix on the Linux kernel (STR #3884) it looks like
that all known problems of libusb-based USB printing (after deprecation of
the "usblp" kernel module) are solved together with these two patches on
the libusb-based "usb" CUPS backend. So I highly recommend the inclusion
of the two patches in the upstream repository of CUPS, for both CUPS 1.5.x
and 1.6.x.
