I think you may be right that the scanner is USB-1.1 , I have unfortunately only tested with scsi under windows and I dont have access to a Windows machine currently.
What I could find out on google it seems to be usb-1.1 but im not 100% sure. I tried setting the scanning speed to low in xsane but the speed is the same as with normal speed still when scanning, i would think that this could fix the going back and forth of the scanning head because of the scanners potential usb-1.1 bottleneck ? /michael ole olsen gnu at gmx.net On Mon, 14 Apr 2008, m. allan noah wrote: > no, i meant the scanner is usb 1.1. have you tried using the usb under > windows? > > allan > > 2008/4/14 Michael Ole Olsen <gnu at gmx.net>: > > Hello again > > > > It's a USB-2.0 machine (the hub is integrated on the motherboard, > > ASUS A7N8X deluxe), and I have had no other issues with the usb hub > > running fullspeed; I get fine transfer speed to my camera with gphoto2 > > and to my usb-sticks. > > > > No problems under Windows and also no problems when using the scanner with > > scsi or scanner-server (rj45), so the scanner isn't wrecked. > > > > I cannot use the SCSI feature on this computer though - and I don't have > > the scanner server here, that's why I want to use it with USB. > > > > > > > > /michael ole olsen > > > > > > > > > > On Mon, 14 Apr 2008, m. allan noah wrote: > > > > > On Mon, Apr 14, 2008 at 10:34 AM, Michael Ole Olsen <gnu at gmx.net> > > wrote: > > > > Hello, I am having problem using my HP ScanJet 6300C with libusb and > > > > xsane+sane backend from debian testing.
