[sane-devel] Microtek ScanMaker 636 at Advance Hostadapter

[Nicolas Michael]

Hi!

I have a SCSI scanner "Microtek ScanMaker 636" on an "Advance 2911U" 
hostadapter (using module "atp870u"). This scanner has been working with an 
older version and an onboard SCSI controllen without any problems.

Now (Kernel  2.4.18, SuSE Linux 8.0, xsane-0.83) I cannot get it working. (A 
ZIP drive on this hostadapter is working properly.) The scanner is terminated 
correctly.

Yast2 identifies the scanner at /dev/sg15 correctly. But when trying to scan 
with xsane (or the Yast2 Testscan function) the scanner software hangs. The 
green led at the scanner turns off und even the ZIP drive doesn't work any 
more.... The hostadapter is dead....

I get the following output an the error console:

Concerning my IDE CDROM drives I have the following settings (but even without 
ide-scsi the problem shows up):

/etc/modules.conf:
alias scsi_hostadapter atp870u
alias scsi_hostadapter2 ide-scsi
...
alias char-major-21 sg
...
options ide-cd ignore='hdc hdd'
pre-install sg modprobe ide-scsi


Any ideas?
Thanks for your help already!!!
