Hi all, I've some problems with my ADF scanner. It's a Canon DR-2580C.
Scanning works fine, as in: the pnm files get created and contain valid content, but scanimage does not terminate! It hangs after the following warning: libusb: warning [libusb_close] internal signalling write failed, closing anyway Some background information: I'm running nixos-unstable. $ scanimage -V scanimage (sane-backends) 1.0.25git; backend version 1.0.25 $ scanimage -L device `v4l:/dev/video0' is a Noname Integrated Camera virtual device device `canon_dr:libusb:003:013' is a CANON DR-2580C scanner $ cat /sys/bus/usb/devices/3-2.2/power/control on ==> I don't believe that this is cause by usb autosuspend Furthermore, I had the scanner connected directly to my Thinkpad's USB port $ SANE_DEBUG_CANON_DR=30 scanimage -d 'canon_dr:libusb:003:013' --resolution=300 > 2580-1.pnm 2>2580-1.log This just hangs. The 2580-1.log can be found in [1], but I have included the last few lines of the log below: [canon_dr] sane_cancel: finish [canon_dr] sane_close: start [canon_dr] disconnect_fd: start [canon_dr] disconnecting usb device libusb: warning [libusb_close] internal signalling write failed, closing anyway Do you have any clue what might be the problem? Thanks, Maarten [1] http://maarten-hoogendoorn.nl/public-uploads/sane/2580-1.log
