If you are buying this to connect to a Nokia phone beware. It is a non-Nokia part and will no easily interface with the Nokia software. It uses a different chipset than the Nokia data interface cable, which prevents it from using the standard Nokia drivers. You may be able to get it working, but I have spent about four hours and have not met with success. I installed the drivers provided. I installed Nokia's drivers. I even installed the PL-2303 serial driver, but I could not make it work.Also note that this cable is a serial interface. If converts the USB connection to your computer into a serial port, so you will likely not be happy with the data transfer speed.I would recommend against this purchase. Spend the extra money and buy the real thing. You'll save yourself some head aches and heart aches.God bless you.
