I'm just trying to start using SANE. I'm puzzled by the error message
# scanimage --version
scanimage (sane-backends) 1.0.19; backend version 1.0.19
# scanimage -L
device `umax1220u:libusb:004:002' is a UMAX Astra 2100U flatbed scanner
# scanimage -d umax1220u:libusb:004:002 > outfile.pnm
==> scanimage: sane_start: Invalid argument
- I get the same result on Fedora 10 x86-64 and on Ubuntu 8.10 AMD64.
(The log above is from Fedora/)
- The FAQ has an entry on this message but it doesn't seem to help in
- An strace on the Fedora system shows that the device is opened.
Just before the failure, scanimage does a bunch of USBDEVFS_CONTROL
ioctls on the device's file descriptor.
(I was about to get rid of the scanner because we switched from
MS Windows years ago. Then I discovered that SANE now supports this
model. Great! Thanks!)
