On Feisty this has improved. I can no longer make the printer disappear
permanently. However doing repeated runs of the cups usb backend
produces differing results:
while true; do /usr/lib/cups/backend/usb; done
direct usb://Brother/HL-1050%20series Brother HL-1050 series Brother HL-1050
series
This problem is still here in Ubuntu Edgy but as previously mentioned it
could be a hardware fault...

OK after a lot effort I have narrowed this down a bit. I can show the same
problem using:
watch -d=cumulative --interval=0.5 /usr/lib/cups/backend/usb
as root on two different consoles. It doesn't take long for them to start
alternate showing and not showing the printer and if you are unlucky
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
please recheck after a dist-upgrade to dapper 20060414, removal and
reinstallation of the printer
