Comment 108 for bug 35638

I tried setting up a new printer, R220-test, with the URI as suggested. Otherwise, same driver, etc. It worked, I made it default, printed again, then suspended.

When I came back from suspend, the old Stylus-R220 definition was working fine and the new default R220-test was "unplugged" !

$lsusb
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 003: ID 04b8:0005 Seiko Epson Corp. Stylus Printer
Bus 001 Device 001: ID 0000:0000

Running that command did not make R220-test become functional.

I then made the old Stylus-220 definition the default again, and re-suspended.

Then both R220-test and Stylus-R220 come up as "unplugged". lsusb shows nothing on Bus001 or 002. But just running that command makes both R220-test and Stylus-R220 work.

$lsusb
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 008: ID 04b8:0005 Seiko Epson Corp. Stylus Printer
Bus 001 Device 001: ID 0000:0000

Color me totally puzzled. Hopefully it means something to you!
