Hello Randolph, your problem has nothing to do with fork(), the backend does not reach to the position where the reader_process is started, the problem already ooc= urs while calibration:
[umax] scanner reserved [umax] sending 3 * 256 bytes of gamma data for RGB [umax] send_gamma_data [umax] using gamma download curve format type 2 [umax] set_window_param [umax] window descriptor block created with 82 bytes [umax] window(s) set [umax] start_scan [umax] starting scan [umax] do_calibration [umax] wait_scanner [umax] scanner reports Error during device I/O, waiting ... [umax] scanner does not get ready [umax] trying to release scanner ... But to answer your other question at first: the scanner IS supported. There are some possible reasons for the problem like - bad scsi buffer size - bad scsi driver - bad scsi cables or termination Please redo the test with export SANE_DEBUG_SANEI_SCSI=3D128 and please also take a look at the kernel log file if you find any scsi errors there.
