[sane-devel] Problem with HP ScanJet 8290 and scsi

[Marc F. Clemente]

I have a problem connecting a ScanJet 8290 by scsi.

The computer: AMD64 running Linux kernel version 2.6.15

Scsi card (lspci -v):
0000:00:0e.0 SCSI storage controller: Adaptec AHA-7850 (rev 03)
        Subsystem: Adaptec AHA-2904/Integrated AIC-7850
        Flags: bus master, medium devsel, latency 32, IRQ 21
        I/O ports at b400 [disabled] [size=256]
        Memory at fb200000 (32-bit, non-prefetchable) [size=4K]
        Capabilities: [dc] Power Management version 1

Scanner is connected to the computer with the scsi cable.

Scanner is recognised by the computer (kern.log):

Scanner is recognised by sane-find-scanner (sane-find-scanner -q):
found SCSI scanner "HP C9930A 1.03" at /dev/sg2

Scanner is recognised by scanimage (scanimage -L):
device `avision:/dev/sg2' is a Hewlett-Packard ScanJet 8200 flatbed scanner

Scanimage does not work...  It just hangs when I try to scan a picture:

What am I doing wrong?  What's the meaning of "truncating write data from requested 28 bytes..."

Any suggestions?  Do I need to try something different?

Thanks,
