what is the gps device name?

[wibble]

Docs for this model seem thin on the ground, but it looks like they have a fair bit in common. This is guesswork based on docs I've found while waiting for mine to turn up. Check dmesg for ttyUSB interfaces which might get renamed by udev rules. One will be a read-only one for the NMEA output, and another takes AT commands for configuring it. I assume you wouldn't be asking if gpsd was connecting to it already.
