Thank you Gerhard and Manuel, that lead me to make the command work one time and have a test scan correctly done with one device, but trying again: $ lsusb |grep Canon Bus 003 Device 010: ID 04a9:2206 Canon, Inc. CanoScan N650U/N656U $ scanimage -d plustek:libusb:003:010 --format=jpeg -p -v --mode Gray --resolution 150 -x 215 -y 297 > test.jpg does not respond. The same device works on windows, with the same usb port, same cable and same hardware (well, actually it is a Virtual Machine inside the linux box). Also, trying again scanimage -L it hangs for >15 minutes, then I kill it and try again in Windows it still work :-/ Can you help me going a step further please?
