Snapscan failure (AGFA Snapscap 1236s)

The snapscan backend is not working properly with my Snapscan 1236s.
'scanimage -T' fails on all tests, and the kernel reports this when I
try to access the scanner:

kernel: (scsi0:0:2:0) Data overrun detected in Data-In phase, tag 0;
kernel: Have seen Data Phase. Length=0, NumSGs=0.

I'm running RedHat Linux 6.0 with kernel 2.2.10. Here are the output
of /proc/scsi/aic7xxx/0:

Adaptec AIC7xxx driver version: 5.1.17/3.2.4
Compile Options:
TCQ Enabled By Default : Enabled
AIC7XXX_PROC_STATS : Disabled
AIC7XXX_RESET_DELAY : 5

Adapter Configuration:
SCSI Adapter: Adaptec AIC-7850 SCSI host adapter
Narrow Controller
PCI MMAPed I/O Base: 0x80200000
Adapter SEEPROM Config: SEEPROM found and used.
Adaptec SCSI BIOS: Disabled
IRQ: 11
SCBs: Active 0, Max Active 1,
Allocated 15, HW 3, Page 255
Interrupts: 963
BIOS Control Word: 0x0000

Extended Translation: Disabled
Disconnect Enable Flags: 0x00ff
Tag Queue Enable Flags: 0x0000
Ordered Queue Tag Flags: 0x0000
Default Tag Queue Depth: 8
Tagged Queue By Device array for aic7xxx host instance 0:
{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}
Actual queue depth per device for aic7xxx host instance 0:
{1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1}

Statistics:

(scsi0:0:1:0)
Device using Narrow/Async transfers.
Transinfo settings: current(0/0/0/0), goal(0/0/0/0), user(25/15/0/0)
Total transfers 268 (268 reads and 0 writes)


(scsi0:0:3:0)
Device using Narrow/Async transfers.
Transinfo settings: current(0/0/0/0), goal(0/0/0/0), user(25/15/0/0)
Total transfers 1 (1 reads and 0 writes)

(Currently, the Snapscan scanner is not present). Any ideas?
