I don't tend to do dis-upgrades willy nilly. However I have recently upgraded CUPS packages which I suspect was what you were getting at.
The output of lpinfo -v has changed to:
network socket
network beh
network bluetooth
direct usb://Brother/HL-1050%20series
direct hp:/no_device_found
network http
network ipp
network lpd
network smb
but as before from time to time the direct usb:// line will disappear even though the device is still shown in lsusb and there are no messages of its disappearence in dmesg.
