	Hello,

	in the logs, the slope tables that drive motor speed are clearly bogus.
Currently, only the codepath taken when the motor and ccd are for the MD5345 
is well tested. It works for the MD6471, and I got a success report for a 
MD6228 .

	As an experiment you could try to change CCD_UMAX to CCD_5345 and 
MOTOR_UMAX to MOTOR_5345 in the hp2400c_model structure (in genesys_devices.c).

	Is there any chance you can use usbsnoop to log a 100 dpi color scan
under windows? Having such a log would allow us find what are the exact values
to set up in genesys_devices.c .

Regards,
	Stef
