[sane-devel] UMAX Astra 2200 USB weirdness

[ope]

What I see in messages are a lot of messages saying:
kernel: usb_control/bulk_msg: timeout
last message repeated 2 times
last message repeated 3 times
...

and after 10 minutes or so I will see:
kernel: scanner.c: read_scanner(0): excessive NAK's
received
