    Default Unknown Device ( USB Controllers)

    Iím running windows 7 ultimate 64 bits. I tried to connect my Amateur Radio which communicates with windows via USB. Iím getting Unknown Device even if the latest drivers from Silicon Labs are installed, CP210 drivers. What should happen is that I should have 3 virtual comports available.

    It seems that windows didnít see the drivers and tried to install some of its own drivers: version 6.1.7601 17586. Devicepath: USB\VID_0000&PID_0000\8&15D78051&0&3
    How di I force windows to use the drivers from Silicon Labs?

    I have tried too uninstall device, rebooted and all the usual ways without any luck. Windows has stopped the devise from working with error codes 10 and 43. It must be a way to get windows to see the device, start it and install the right drivers from Silicon Labs.

    Anyone please?

    Hi Wilford and Welcome to The Forum.

    Not 100% sure as to why Windows is giving you error codes, but you can stop Windows from installing its choice of driver by going into System Properties >> Advanced System Properties (on left of window) >> Hardware >> Device installation settings button.

    FOR INFO
    To manually install drivers not supplied as an installer set up:
    Driver Install - Manual method
    1. Download the driver and extract it to a folder.
    2. Open the Device Manager.
    3. Right click the device you wish to change the drivers for. You can select Properties > Driver > Driver Details to check you have the right device.
    4. Choose Update Driver Software.
    5. Select Browse My Computer For Driver Software.
    6. Select Let me pick from a list of device drivers on my computer.
    7. Select Have disk...
    8. Select Browse..
    9. Navigate to the extracted folder and double click on the .inf file
    10. Hit OK, then Next and the driver(s) will then begin to install.

    I have already tried the above. Sorry to say that this did,t help. Still unknown device and the Silicon Labs drivers are still not used because the device already use the best drivers.
