Hi ,
In my box I have Redhat 9.
I must connect via SCSI Interface Umax Mirage II scanner.
SCSI adapter is Acard AEC-6712TU.
Linux System logs contain:
Oct 4 19:19:05 localhost kernel:ACARD AEC-671X PCI Ultra/W SCSI-3

Ultra/W/LVD SCSI-3 Adapter Driver V2.6+ac
I have never used the atp870u driver, but I assume that this driver
should print some message about the devices it detected on the bus as
other drivers do. In other words: for some reason it could not find the
scanner.
My qustion is:
How to install correctly the scanner and the scsi adapter - I must make
any mistake.
I do:
modprobe sg
modprobe atp870u
[root@localhost scsi]# lsmod

Attached devices: none
here you should get 3 lines describing the scanner.
I think it should be also sg directory in /proc/scsi
yes -- but I don't know, if the SG driver creates this directory, if it
does not see any devices.
[root@localhost root]# sane-find-scanner
# No SCSI scanners found. If you expected something different, make sure
that
that's because sane-find-scanner simply reads /proc/scsi/scsi, and this
file is empty.
# you have loaded a SCSI driver for your SCSI adapter.
# Also you need support for SCSI Generic (sg) in your operating system.
# If using Linux, try modprobe sg.
Can anyone help me ?
I don't have a really good hint. The core problem is that the atp870u
driver does not find the scanner, hence any attempt to access it will
fail. Unfortunately the kernel sources don't seem to contain useful
documentation e.g. about module parameters.
A very simple attempt could be to issue the command
echo scsi add-single-device 0 0 6 0 /proc/scsi/scsi
If the atp870u driver performs a bus reset and does not wait long enough
for SCSI devices to finish their reset procedure, it will not find the
scanner, when it scans the bus for devices after the reset.
