to diagnose this, we are going to need a usbmon trace. You can find instructions on how to do this at https://www.kernel.org/doc/Documentation/usb/usbmon.txt
also, what package does that 'hp' app come from ? make sure you have the latest version of that.
(In reply to comment #4) > also, what package does that 'hp' app come from ? > make sure you have the latest version of that. I guess, this was /usr/lib/cups/backend/hp # rpm -qlf /usr/bin/hp-info | grep /hp$ /usr/lib/cups/backend/hp
