PL 2303 – The Device Cannot Start

What used to be the norm is now the exception, I had a project that made use of a serial connection, but all my computers lacked a serial port. After searching online I found a cheap USB to Serial cable that convinced me.

To be specific it was the Bytecc BT-DB925 built on the PL 2303 USB to Serial Bridge Controller by Prolific. While the built quality was excellent the supplied driver failed to properly install on my Windows 7 x64 system rendering the cable useless.

The supplied driver is the PL2303_Prolific_driverInstaller_v1210.exe, which never worked for me.

The Solution

Instead, the working driver is PL2303_Prolific_GPS_AllInOne_1013.exe. (Hosted locally).

The download link at USGlobalSat is broken PL2303_Prolific_GPS_AllInOne_1013.exe

Although it says GPS the driver is functional, beats having a useless cable around.


Uninstall the first driver and install the second one, after the installation is done reboot the system and then connect the USB to Serial cable. This seems to be a common problem on the Internet, I just wish the manufacturer would provide the functional driver.

    Thank you!
    I have WIN7 x 64 and TrandNET USB-COM TU-S9 and try to install: PL2303_Prolific_DriverInstaller_v130 (15.07.2010) – This device cannot start. (Code 10) is resalt.
    After installing PL2303_Prolific_GPS_AllInOne_1013.exe – it’s no problem.

    Many thanks!!!
    My theory is that some Chinese manufacturing houses are using chips intended for GPS application (like surplus chips). This offers them competitive cost. That’s why we end up having to use a GPS driver to make this work. Great advice, thanks again.

      Theory accepted, it makes sense from a business point of view.

    Why did you erase the driver, oh why?

      Fixed, I don’t know why moved the directory where the driver was stored. It should be available again, if not post another comment.
