No, with that I wouldn't be able to get hold of the scanner.

I did a successful preview and a failed scan where the whole server hung until I reset the scanner after which I had to reboot the machine since ths SCSI driver was locked by something unknown. However any attempt to repeat this failed. I retried previews using the same settings (-d255) and I got to see most of the image and then the preview window was cleared. Consistently dozens of times, but no hanging. Then I lowered the debug level to 10. No change. And then to 1. Success. Even scanning worked for the dozen times I tried. Then I removed the debug flags, and enabled the sane daemon through xinetd again. Everything still worked. And then I coldbooted to see if that would repeat the problems, but no. It just works. I'm puzzled, wrong phase of the moon?.. but I don't think it changed during last evening. Xsane is great when it works though. -- robin
