Michael Hatzold (CCed) reports a problem with ipp-usb. The printer provides a 7/1/4 interface on USB, meaning that it supports IPP-over-USB and with this, according to the standards, driverless printing (and scanning if it is a MFP).

I'm the author of ipp-usb, and I want to investigate this problem.

May I ask you to gather ipp-usb logs? To do so, please do the following:
1. Remove all old ipp-usb logs (rm /var/log/ipp-usb/*)
2. Restart ipp-usb and reproduce a problem
3. Send me all files from the /var/log/ipp-usb/ directory
