How would that match up with a char > device driver? ./drivers/usb/serial/garmin_gps.c ? Hmm, some cleanups would be welcome there... plus it would be good to know what is its interface to userland... it is not easily apparent from the code. Actually, having some kind of common support for GPSes in the kernel would be nice. (Chardev that spits NMEA data?) For example N900 GPS is connected over network (phonet) interface, with userland driver translating custom protocol into NMEA. Not very nice from "kernel should provide hardware abstraction" point of view.
