This works when I set SANE_DEBUG_GENESYS_LOW=7 but not when I set SANE_DEBUG_GENESYS_LOW=6. Diff-ing the output, I see in particular: [genesys_low] sanei_genesys_read_feed_steps +[genesys_low] sanei_genesys_read_hregister(0x108)=0x00 +[genesys_low] sanei_genesys_read_hregister(0x109)=0x00 +[genesys_low] sanei_genesys_read_hregister(0x10a)=0x4c [genesys_low] sanei_genesys_read_feed_steps: 76 steps -[genesys_low] sanei_genesys_read_hregister (0x101): failed while reading register: Invalid argument -[genesys_low] sanei_genesys_test_buffer_empty: failed to read buffer status: Invalid argument When I run simple-scan in the debugger (without SANE_DEBUG_GENESYS_LOW set), put a breakpoint on sanei_genesys_test_buffer_empty() and simply continue it immediately I am able to scan. So proably indeed a timing problem.
