[sane-devel] sane-umax1220u fails with Umax 2000U

Sat Jan 9 21:43:39 UTC 2010

Hi Stef,

thanks for your hint.

Here is the interesting part of the log:

[umax1220u] UMAX_open_device: Scanner is a 2000U. Expect color
problems :)
[umax1220u] csend: cmd = 0

I didn't see any kernel log messages concerning USB problings. Only
disconnecting and and subsequently reconnecting the scanner was logged:

[ 5405.328052] usb 5-2: USB disconnect, address 2
(interrupt USB connection to scanner)
[ 5411.252022] usb 5-2: new full speed USB device using uhci_hcd and
address 3
[ 5411.395205] usb 5-2: configuration #1 chosen from 1 choice
(reconnect scanner)

The scanner has been working with Windows and an older Ubuntu release on
another PC.

Does this information give any hint how to proceed?

Thanks in advance,

Albrecht
