You might check the function usb_UpdateButtonStatus() in plustek-usbhw.c
This distinguishs between KYE/Plustek and other devices. Maybe this 
assumption is wrong!

Use the program ./sanebuttonsd (from the experimental tree of SANE-CVS) and
the SANE_DEBUG_PLUSTEK facility from the backend to check for the correct
values...

If the detection is wrong, we might need to change the Misc I/O settings,
if only the values reported are wrong while pressing the buttons, maybe
only the function mentioned above is wrong...
