"ACM" stands for "Abstract Control Model", see page 26 (printed page 15) 3.6.2 Abstract Control Model in http://cscott.net/usb_dev/data/devclass/usbcdc11.pdf: With an Abstract Control Model, the USB device understands standard V.25ter (AT) commands. I.e. your device acts like a modem, and /dev/ttyACM0 is the serial device which connects to it (like my old usb posts modem). Try connecting to it with "cu -l /dev/ttyACM0 -s 4800" or try and see if xgps finds it. I don't know how the AT commands gets into the picture, but somehow you should see nmea traffic coming, have a look at https://en.wikipedia.org/wiki/NMEA_0183.
