The problem is not the protocol, the GPS should be in NMEA mode. Indeed, if I connect it to my desktop running Ubuntu it is detected, and I'm able to get data from it, but just because the correct garmin_gps module is loaded. The problem is that that module is only available for the kernels 2.6, and I have the 2.4 on my router. Anyway the GPS is detected correctly from the router: [EMAIL PROTECTED]:~#lsusb Bus 004 Device 001: ID 0000:0000 Bus 004 Device 008: ID 05e3:0608 Genesys Logic, Inc. Bus 004 Device 009: ID 0930:6540 Toshiba Corp. Bus 004 Device 011: ID 091e:0003 Garmin International GPSmap 60C / GPS 18 / Vista C
but for some reason gpsd can't get the position from it (I have GPSD,P=?, instead of GPSD,P='some position value').
