I have installed a fresh gutsy 64 bit on a Dell E521 AMD machine, and have the same problem as Andreas Gustafsson
lsusb shows the follwing for my HP SCanJet 4100C Bus 001 Device 003: ID 03f0:0101 Hewlett-Packard ScanJet 4100c sane-find-scanner seems to find my usb scanner - HP ScanJet 4100C all the time output : found USB scanner (vendor=0x03f0 [Hewlett-Packard], product=0x0101 [HP ScanJet 4100C]) at libusb:001:003 however xsane sometimes does not detect it, and if it detects it sometimes does not show it can scan in grayscale, ... as with Andreas Scanimage -L sometimes core dumps, sometimes only finds a usb logitech video camera I also have connected and sometimes does find the ScanJet 4100C I have some debugging info for the hp sane driver by doing the following : export SANE_DEBUG_HP=255 there are three behaviors for scanimage -L 1. core dump 2. ScanJet 4100C not detected - output attached 3. ScanJet 4100C detected - output attached the following are the messages I think are relevant : [hp] hp_attach: "libusb:001:003" [hp] sanei_hp_device_info_get: searching libusb:001:003 [hp] sanei_hp_device_info_get: check libusb:001:003 [hp] hp_get_dev: New device libusb:001:003, connect-usb, scsi-request=0 [hp] sanei_hp_device_new: libusb:001:003 [hp] sanei_hp_device_info_get: searching libusb:001:003 [hp] sanei_hp_device_info_get: check libusb:001:003 [hp] hp_GetOpenDevice: device libusb:001:003 not open [hp] hp_nonscsi_open: open usb with "libusb:001:003" [hp] hp_nonscsi_open: device libusb:001:003 opened, fd=1 [hp] hp_AddOpenDevice: added device libusb:001:003 with fd=1 [hp] scsi_flush: writing 2 bytes: [hp] 0x0000 1B 45 .E [hp] sanei_hp_device_info_get: searching libusb:001:003 [hp] sanei_hp_device_info_get: check libusb:001:003 [hp] scsi_flush: writing 7 bytes: [hp] 0x0000 1B 2A 73 32 35 37 45 .*s257E [hp] sanei_hp_device_info_get: searching libusb:001:003 [hp] sanei_hp_device_info_get: check libusb:001:003 [hp] sanei_hp_device_info_get: searching libusb:001:003 [hp] sanei_hp_device_info_get: check libusb:001:003 [hp] scl_inq: read failed (End of file reached) [hp] scl_errcheck: Can't read SCL error stack: End of file reached [hp] hp_nonscsi_device_new: SCL reset failed [hp] scsi_close: closing fd 1 it seems the hp sane backend gets an end of file error I have tried the following but it did not help https://bugs.launchpad.net/ubuntu/+source/kvm/+bug/156085/comments/5 thanks, Koen ** Attachment added: "scanoutputs.tgz" http://launchpadlibrarian.net/10311381/scanoutputs.tgz -- scanimage -L crashes with HP ScanJet 4100c https://bugs.launchpad.net/bugs/119819 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
