Hi,
i have looked everywhere but couldn't find any info on this: i try to hook
up two scanners to a linux box and let them scan at the same time. Because
my scanners (both UMAX Astra 2400S) seems to block the scsi-adapter for a
few seconds, i have installed 2 of them, one for each scanner. Now, when i
try to scan simultanously, the last scanner still waits until the first is
finished. I have no idea what is blocking: sg, sane, sane-umax. Does anybody
know of any way to make this possible?
(my goal is to have a scan-server with multiple scanners attached to it,
remotely operated by either saned or sanecgi).
My setup is:
Debian 2.1
kernel 2.0.36
2x adaptec 2904 (european 2906)
2x UMAX Astra 2400S
