USB Driver Problem

Venkatesh V

Dear Friends, I am new to USB development in LPC2378. I have taken USB device driver from the following path

C:\Keil\ARM\Boards\Keil\MCB2300\USBCDC

But it's not installing the driver file in PC. Its showing USB Device Not Recognized and Unknown device.what should i change in that code.Is there any modifications?

    If your OS is Win-XP 32bit,
    the driver of "C:\Keil\ARM\Boards\Keil\MCB2300\USBCDC" should work for you.

    Did you change anything like VID/PID in the source code?

    Did you follow the instruction in the Abstract.txt?

    Driver Installation:
--------------------
     "Welcome to the Found New Hardware Wizard" appears
     - select 'No, not this time'
     - press  'Next'

     - select 'Install from a list or specific location (Advanced)'
     - press  'Next'

     - select 'Search for the best driver in these locations'
     - check  'include this location in the serach'
     - set to <project folder>
     - press 'Next'


     "Hardware Installation" appears
     "has not passed Windows Logo testing..."
     - press 'Continue Anyway'

     "Completing the Found New Hardware Wizard" appears
     - press 'Finish'

    Hi,

    I did not change the code including VID/PID.
    whenever, if i switch ON my board,
    1. "Found new hardware (USB Device)" appears
    2. "Found new hardware (Unknown Device)" appears
    3. "Welcome to the Found New Hardware Wizard" pop up window has not appeared But
    4. "Finally your hardware is installed and ready to use" appears

    But COM port is not assigned for my device and driver is not installed

    May i know the problem?

    thanks,

    Have you ever used the Device Manager of Windows?

    [Control Panel] -> [System] -> [Hardware] -> [Device Manager]

    Plug/unplug your USBCDC device to see what device appears/disappears in the Device Manager.

    Remove that device / Remove the driver of that device.

    Then reinstall the correct driver.

    Hope this helps.

    Hi,
    I knew about Device manager in Windows..

    The same method already we tried after appearing the "Your Hardware is installed and ready to use" window.
    But after installing the correct driver again it was showing "Unknown device".

    thanks,

    Maybe see this:

    List all the non-present USB devices, delete them.
