--- Comment #85 from Ian Powell
Now it looks again like a real issue!
Normally it should "just work" to rerun /usr/lib/cups/backend/usb as many times and as often as you like and it should always detect your printer.
E.g. I can run it 10 times in a row # for in in $( seq 10 ) ; do /usr/lib/cups/backend/usb ; done and I get 10 times exactly the same result.
If you get different results when you run /usr/lib/cups/backend/usb several times there is an issue somewhere:

Only comment#75 shows how it should look when it works correctly.
Comment#2 and comment#79 show different kind of failures.
I've just run your test of a loop for 10 and its all the same as comment #79 -- You are receiving this mail because: You are on the CC list for the bug.
