Microchip PIC18 USB applications quite popular with the series project with PIC18F4550 usb keyboard would be a good example for many people.

I’ve never known USB issues after me pretty puzzling to others with the principles of simplicity, I share my project 18F.

There are 14 buttons pressed them ABCD keys 1-9,0 and prints. Meanwhile, the key pressed at 2 × 16 LCD Viewing. the computer recognizes the device as a keyboard hidden. In the link there, but the whole project isis usb keyboard does not work. I prepare the file isis scheme in terms of connectivity. Codes are written with protons.

the fact that a part of my project I’m making more, but with this situation, many people think it would be an example.
