I have the Microsoft streets and trips with the GPS.
it works very well. so well infact I use it to go geocaching.
but we went looking for a cache today. and well the GPS driver quit on me. weird.
I stole some wireless from a nieghbourig household. but. still no install.
the microsoft website. no help.
went home. tried the actual disk. no help. hmmm hope it isn't fried.
jump to the manufactures website (PharosGPS)
the driver installed. opened streets and trips, and did a com port scan to find the GPS.
and it didn't say microsoft GPS. just gps device. sofar so good.
run outside it finds satilites .. YAH it works fine!!
probable cause. most USB devices have a small EEPROM that says who made the device.
even though the USB to serial chip is made by someone else. so if the memory got erased the microsoft driver will not install cause it can not confirm it is the correct device. and the driver I downloaded is the actual driver for the chip. USB-TO-SERIAL.
yah GPS not fried!!!
