# Add a generic entry (the "Any" with capital 'A' lets it appear at the top of YaST's sorted list):
# This USB ID ("0x03f0" "0x0000") is used as fallback by the YaST scanner autodetection
# via /usr/lib/YaST2/bin/autodetect_scanners which calls "hp-probe -busb -escan"
# because hp-probe does not show the USB ID. With this USB ID the generic entry matches
# to any autodetected HPLIP USB all-in-one device (the "-escan" excludes plain printers)
# so that the usually right driver (hpaio) can be preselected by YaST.
# Nevertheless, to be on the safe side, the support status is set to "untested".
