For some years I had been using my HP Scanjet 2400 with the Elcot driver which is configured by the entry hp2400 in dll.conf
Then sometime in, I think, June 2011 as part of a regularly occurring automatic update of my Ubuntu 10.04 LTS system this driver was replaced as part of the SANE development. The new driver is configured by an hp2400 entry in genesys.conf. It is is still under development by Alexey Osipov. It was initially able to produce a greyscale image of a colour document but now it fails to work at all. 'scanimage -L' fails with Segmentation Fault If I go back to the Elcot driver then 'scanimage -L' outputs: scanimage: symbol lookup error: /usr/lib/sane/libsane-hp2400.so.1: undefined symbol: sanei_usb_init Should I buy a modern scanner which the SANE Web page asserts does work and attempt to install it or shall I continue to try, with your help, to get this hp2400 model to work? --- Even to get it to be consistently recognized by 'lsusb' can be a struggle. Please help, Bertie Coopersmith.
