MS-GM-03A 16-Channel USB NMEA-0183 GPS Receiver
I bought one of these, thinking it would work great, so I plugged it in to my desktop, following their instructions, opened up something to watch the new serial port it created (that part worked), then I watched it do nothing, nothing at all.  no data received or anything.  I went looking for the manufacturer to get some assistance, and none exists.  I suggest avoiding this thing.
