i am comunication any hardware with PC through USB port using PIC18F4550 and using Visual basic 2005 please help me with send vb source code

 

What good would that do you. If you don't know anything about USB then having the code won't do you much good assuming that what you want exists and some member is willing to give it to you.

Mine too. Except I started at the beginning by downloading and reading the USB specification. You should too.

http://www.usb.org/developers/docs/

Start with the USB 2.0 specification
The 3.0 spec is just now coming out

You can take my advice or ignore it. I really don't care which way you go.
