[sane-devel] UMAX Astra 1200S/Linux-2.4.19 Freeze

[Oliver Rauch]

Hallo David,

some people reported that it is necessary to disable SCSI bus reset
in the driver or bios of the scsi controller. May be there was a change
in the kernel driver you use.

To enable debugging do:
export SANE_DEBUG_UMAX=12
export SANE_DEBUG_SANEI_SCSI=128

you can redirect the output of the stderr with the option "2>debug.txt",
e.g.:
xsane 2>debug.txt

Bye
Oliver
