I need to connect PIC18F4550 to my PC through USB port. As this PIC is having dedicated USB port i need to make use of that.
I loaded the boot-loader to the device. I used MCHPUSB.hex file. My device is connected to 20MHz crystal. I got the driver from" https://www.electronics-diy.com/download_file.php?file=USB IO Board Drivers ". while the device is connected to PC, it i is showing UNKNOWN DEVICE. I am using WINDOWS7. When i pointed the device to the driver i downloaded it is showing Driver is UP-TO-DATE. But still showing unknown device.

Can anyone please help me.
