[sane-devel] sane-find-scanner vs. scanimage --list-devices?

[Peter Kirchgessner]

Hi Steven,

now the backend is talking to the scanner. But it is getting some
problems with the communication. Some new Linux kernels have a bug. Add
to your hp.conf-file below the /dev/scanner a line

option disable-scsi-request

Maybe this can solve the final problem.
