Hello,

I am trying to develop the USB interface with a PIC18F4550 with the help of a EasyPIC6 Development Board. I am using MPLAB v8.56. After looking through the USB device example (HID Device Custom) on Microchip Libraries for Applications (MLA), I could build the hex file successfully for my project.
Then, I used mikroProg Suite to write the hex file onto the chip.
After it is written successfully, I get a pop up saying "USB device not recognized".

I am attaching the zip package below.

I guess the problem could be with the descriptors. But I am not sure. It would be great if someone can help me out.

Regards,
Vineeth
