Maybe you > got a defect device somehow? Ebay? I tried periodically over the 18 months to get it configured to run on various versions of Redhat Linux with a USB connection. Each time I failed and went back to using it on Windows XP, where it worked without problems. The scanner was the main reason that I kept a dual boot of Windows XP. I finally started getting reasonable scans and ADF support with XSANE under Fedora Core 3. Most of the time I gave up after hearing funny noises that did not happen in Windows XP and I could not resolve in Linux. Last I saw, your advice was to immediately unplug the scanner in this case, but I saw no way to troubleshoot it in Linux, so I posted a note, and waited for the next version of the avision driver. It was only recently that I discovered that I could bypass the power save and paper jam problems by unplugging and replugging without a reboot. The paper jam problem is very annoying, since the hardware appears to signal the software, and, in Windows, under FineReader, I get a paper jam message, clear the jam, and restart the scan where I left off. In Linux, I discover the jam, clear it, and unplug and replug the scanner, but XSANE will not resume. I have to save the pages already scanned, stop and restart XSANE, and only then can restart the scan. I have also used this scanner for years, but the only good results I got were on Windows XP. I got the scanner new, directly from HP. ... > > Does anyone know of an ADF scanner that has good SANE support?

What should I do if the funny noises recur? Is the avision support better for SCSI than for USB? Tom
