Hi, For a few days I've tried to extend scanbuttond to include also the value that's displayed in the little LCD panel in my HP ScanJet 5590 (by making scanbuttond run the script with one more arg). Does anyone know how it's supposed to be read?
According to sane backend 'hp5590' source, the devices EEPROM must be read. Comparing with reading button status, how different an operation this is? All I get is usbfs error lines (ret -110 --> timeout) although I believe the code is identical... Has anyone actually gotten the value out correctly? -- Matti Viljanen matti.viljanen at wippies.com
