Package: cups
Version: 1.4.0-5
Severity: normal
Hi,
I have an USB connected Epson Stylus Photo R360. It worked fine with
cups 1.3, but it does not work with 1.4. The kernel log shows the
following when turning the printer on:

[the last line repeated endlessly]
If I remove/blacklist the usb-storage module, then printing works, but
that of course breaks removable storage devices. Previously the
usb-storage and usblp drivers coexisted peacefully and was able to drive
the same device simultaneously; that seems to be broken now with libusb.
