For those struggling to get their old Genius Colorpage-SP2
scanner with the MS-PNR card working in Linux, here is the
solution:
ATTENTION:
This has only been verified in kernel 2.6.0-test5.
It will NOT work with the 2.4.X kernels or older.
Compile your kernel with the following options enabled:
ATTENTION: With 2.6.0-test5, the patch attached is required.
SCSI Device Support:
SCSI Low-Level Drivers:
> Generic NCR5380/53c400 PIO Support.
> Enable NCR53c400 Extensions.
If you compiled it as monolithic, put the following line
in your lilo.conf:
append=3D"ncr53c400a=3D<PORT>,255"
Or, if you compiled it as a module, activate it with this:
(Remember to have your scanner turned on!)
modprobe g_NCR5380 ncr_53c400a=3D1 ncr_addr=3D<PORT> ncr_irq=3D255
The <PORT> value must be one of those: 0x280, 0x290, 0x300,
0x310, 0x320, 0x330, 0x340, 0x350
(I use 0x280 here with no problems.)
And let SANE detect your scanner with sane-find-scanner!
It is reported as a Microtek Model, as it should be, and
works flawlessly!
PATCH:
There is a strange problem with the driver in 2.6.0-test5,
that requires you to apply the patch below. This patch might
not be necessary in future versions.
(Apply it inside drivers/scsi directory)
