New driver for Xyron Personal Cutting System >

[Trackback URL for this entry] 2006-06-06T21:21:25 Xyron cutter:

I really want this Xyron Personal Cutting System paper cutter to be computer controlled. It's normally controlled by removable AT45DB041B 4-megabit flash chips, but it has a secret usb port in it (among a few other secret connectors). The brain is an Atmel ATMEGA64 talking to two L6219DS motor drivers. If I can't talk to the CPU, I will have to talk to the motor drivers (hard to access) or straight to the motors, with my own drivers.

I plugged the usb into a ubuntu laptop, but I didn't see any usual usb handshaking in my logs. Unfortunately there's no reference program to sniff the protocol from. For all I know, the usb port is asleep until the right flash chip is plugged in.
