[sane-devel] supported kernels of cvs
Hi, On Friday 09 December 2005 10:52, Stefan Leichter wrote: Hello all, can someone give an official statement about the supported kernel versions for the current cvs. All i found about this is: CVS is usually only going to work on recent linux kernels (http://linuxtv.org/v4lwiki/index.php/How_to_build_from_CVS). But what is a recent kernel? Is 2.4.32 a recent one? Background: I'm trying to get a Leadtek WinFast TV2000XP Expert (cx88) running on a 2.4 kernel.

[sane-devel] USB scanner slow, hopping back and forward
Hello, I've got sane installed on a LinkSys NSLU2 embedded linux device running the OpenSlug Linux distribution (see http://www.nslu2-linux.org) for use with my Trust Direct WebScan 19200 scanner. The scanner basically works, but scanning is slow due to the scanner hopping backwards quite often. E.g. basically it scans one centimeter, and then hops back half a centimeter. This happens when scanning A4-width at 300dpi. The higher the resolution, the smaller the steps get. I guess every now and then some data gets lost so the scanner has to rescan a line. When doing an 'export SANE_DEBUG_GT68XX=5', I see the following for about every 13th line (at 300dpi A4 width): [gt68xx] sane_read: getting line 190 of 3531 [gt68xx] sane_read: getting line 191 of 3531 [gt68xx] sane_read: exit (line 192 of 3531, byte_count 1987 of 2563, 32768 bytes, 491520 total) [gt68xx] sane_read: start (line 192 of 3531, byte_count 1987 of 2563) [gt68xx] sane_read: getting line 192 of 3531 Does anybody know a solutions for this? Using the scanner on a regular PC running Windows, scans are smooth. Scanning is also smooth on the nslu2 when scanning at low resolutions (preview) or scanning only a small width. Could it be that the NSLU2 is too slow for handling the amount of data? I've also read something about different ohci-drivers, but I'm not sure whether that is applicable to my situation, and how to find/build/use another version.

[sane-devel] USB scanner slow, hopping back and forward
the slug is a little slow, esp. if there are multiple usb devices using the bus at the same time. there are also supposedly issues with usb2.0 hubs on the slug, though i dont remember the details. can you try on a full-sized linux pc? allan (sane and slug developer) On Fri, 9 Dec 2005 s...@rsenden.speedlinq.nl wrote: Hello, I've got sane installed on a LinkSys NSLU2 embedded linux device running the OpenSlug Linux distribution (see http://www.nslu2-linux.org) for use with my Trust Direct WebScan 19200 scanner.
