Bill, I just tried the ScanJet 4100 C with an OpenSuse 10.3 on a 64 Bit machine without problems. On Suse 10.1 32 Bit the scanner was not detected by the USB-layer because of error messages like
Feb 10 11:08:26 capella kernel: usb 1-9: new full speed USB device using ohci_hcd and address 14 Feb 10 11:08:27 capella kernel: usb 1-9: device not accepting address 14, error -62 in /var/log/messages. I needed to unplug the scanner from the power supply and connect the power supply and USB again to get around that. After this I could only access the scanner as root. Otherwise libusb could not open the device because of permission problems. Can you please create a hp.log from a use of xsane that failed: SANE_DEBUG_HP=255 xsane > hp.log 2>&1 and send it back to me ? After xsane failed, please have a look at /var/log/messages if you can find some error message which might be related to the failure. BTW: /dev/scanner is not needed for USB. libusb is used to search a device on the USB that matches the description "usb 0x03f0 0x0101" which is defined in /etc/sane.d/hp.conf and represents the HP ScanJet 4100 C. --Peter m. allan noah schrieb: > well, i think peter might have more clue than anyone else- > > peter? > > allan > > On 2/9/08, Bill Moseley <moseley at hank.org> wrote: >> On Sat, Feb 09, 2008 at 01:32:19PM -0500, m. allan noah wrote: >>> does it work without the hub? how about scrapping xsane or the gimp >>> for a minute, and just use scanimage to try and grab data.... >> Sorry if I was not clear.
