Sorry for the misunderstanding. The backend tries to send two bytes
(the reset command), but never receives the acknowledgement from
the scanner. You wrote in your first message that the permissions
on the device file are 666, can you please verify this.=20
Do you see any messages on the console?=20
Is the scanner connected via a hub? If so, can you try to connect
it directly to the computer and run the test again.
Do you have a second USB cable that you can use? I have seen this
problem once where replacing the cable fixed everything.=20
Do you have any other USB devices connected to your computer?
