[sane-devel] Unkown scanner version in hp5400 backend

[BullGates]

After searching, I manage to enter debug mode to try to see what is
behind the failure in detection of my HP Scanjet 5400 scanner; 
here it is:

[sanei_debug] Setting debug level of hp5400 to 128

[hp5400] attach_one_device: attached /dev/usb/scanner0 successfully
[hp5400] hp5400_open: open returned Device busy

Can the developer of the hp5400 backend (or someone) help me out on
this? Maybe I can help in any way...

Thanks in advance,
Paulo
