http://bugzilla.opensuse.org/show_bug.cgi?id=920937 --- Comment #49 from Ian Powell --- (In reply to Johannes Meixner from comment #48)

When the kernel has issues in its general USB functionality, it could of course be the root cause here but I guess that issues in USB storage are unrelated to issues in USB that are related to printers?

Ian Powell and Saša Janiška, do you really have no usb related error messages in any of "the usual log places" on your systems? I think without usb related error messages it does not make much sense to let a kernel developer have a look, nevertheless:

i'll reboot with the printer turned on and create an attachement of the /var/log/messages and the cups error.log

Oliver Neukum, this issue here is basically that under currently unknown circumstances the CUPS backend /usr/lib/cups/backend/usb does no longer detect USB printers on openSUSE Tumbleweed.

The output from /usr/lib/cups/backend/usb does detect a printer on the USB: - see comment 46

Do you perhaps know of general USB issues in the kernel that is used on openSUSE Tumbleweed that could be the root cause of such issues?
