[sane-devel] scanner.c: read_scanner(0): funky result:-75

[Erik Riedel]

Hi all,

I just downloaded the new sane version 1.08 and tried to use it with my
Nikon LS-40 ED scanner using coolscan2.

I was able to get one scan out of this installation, which makes me
thinking it should work in some kind of way. But all the other times I
tried to scan a picture or to aquire a preview the xscanimage command
just hangs and could not be killed anymore.

The hang is so bad that I can't even kill it with the -9 option.

The error messages I receive during the scan are the following:

scanner.c: open_scanner(0): Scanner device is already open
scanner.c: read_scanner(0): funky result:-75. Consult
Documentation/usb/scanner.txt.
usb_control/bulk_msg: timeout
scanner.c: write_scanner: NAK received.

I believe my config looks ok. Here the output of the /proc/bus/usb/devices

Does anybody have an idea how I can fix this? Any response is appreciated.

Thanks in advance.
