Package: cups
Version: 2.3.3op1-7

Cups does not support Canon CAPT USB printers (this requires a proprietary driver which uses /dev/usb/lp0), but these printers are not blacklisted, so when one is plugged in, cups sets up a new, non-functional printer, and probes the USB device, the kernel logs as a USB disconnect, and disrupts operation of the Canon driver. Running lpstat also seems to do some probe and cause a USB device disconnect. The kernel logs:

Jan 23 23:45:29 debian kernel: usblp0: removed

It appears the fix would be to add CAPT printers to /usr/share/cups/usb/org.cups.usb-quirks as so:

# Canon, Inc. LBP3010/LBP3018/LBP3050 Printer
0x04a9 0x26da blacklist

etc.
