Well guys I have learned to love kismet as with my laptop the windows drivers say the AP still is there 4 miles away

However I got this new Magellan eXplorist 210 which comes with a USB cable, it spits out NMEA 2.1 though the USB cable in windows and assigns it to COM4 though some type of USB to serial emulation.
So is this possible in linux? Doing a lsusb outputs "Bus 004 Device 002: ID 0b20:0406 TransDimension, Inc." which is my GPS. However looking at dmesg it only finds the new device, but does not assgn it to /dev/ttyUSB0 or anything.
So far I have usbserial as a module and have it loaded when I plug the GPS in. Am I missing anything and just incase you ask why I don't use a USB to serial, because my laptop only has USB ports
Thanks
