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?
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, venkat v

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