#492 — Scanner worked under Slackware 12.0 but not under Slackware 13.37

	I have an old Umax Astra 1220S SCSI scanner that used to work 
fine when connected to a PC running Slackware 12.0. The connection is 
made via a SCSI card on the PC that accessed by means of the aic7xxx 
module. I wiped out the OS in the PC, for I wanted to upgrade to 
Slackware 13.37. After this, bearing in mind that the hardware is exactly 
the same as before, the scanner is not even recognized by the driver.

	Some more data: When running under 12.0 the box was running a 
2.6.22.9 kernel, with aic7xxx compiled as module. Under 13.37 the kernel 
is 2.6.37.6, and the scanner is not recognized no matter whether aic7xxx 
is compiled as a module or into the kernel. In fact, in the former case 
the module can't be loaded at all. I won't go into this for I want first 
to show what happens when it is compiled into the kernel. In that case, 
the hardware is detected at boot time and the relevant portion from lshw 
output is the following:

           *-scsi
                description: SCSI storage controller
                product: AIC-7850
                vendor: Hynix Semiconductor (Hyundai Electronics)
                physical id: 9
                bus info: pci@0000:01:09.0
                logical name: scsi0
                version: 03
                width: 32 bits
                clock: 33MHz
                capabilities: scsi pm bus_master cap_list scsi-host
                configuration: driver=aic7xxx latency=32 maxlatency=4 
mingnt=4
                resources: irq:17 ioport:ac00(size=256) memory:cc004000-
cc004fff

	It would seem that the SCSI card in the PC connected to the 
scanner is detected all right. However, sane-find and scanimage do not 
detect it. At a lower level, the scanner does not appear in /proc/scsi/
scsi :-( I made sure of course that the scanner was turned on and, just 
in case, I ran the commands as root.

	Any ideas on what else to try? 

	Quite frankly, I wonder if I should just bite the bullet and 
retire this scanner?

I would try another driver for your scsi card.

From your description I get the impression that the SCSI card is the
problem rather than the scanner.

If aic7xxx.ko does not work fine in Slackware 13.37, maybe aic7xxx_old.ko
works better?

	Well, as it happens so uncannily often, I got things working 
shortly after posting my question. I simply opened up my PC and moved the 
SCSI board to a different PCI slot. After rebooting, the scanner was 
immediately recognized and I could access it as usual with xsane.

	Hardware will forever remain an unfathomable riddle to me.

The biggest problems with computers are hardware, software, and users. The
perfect computer system would not have any of those drawbacks.
