Serial data to USB

[dhouston]

The simplest solution is to keep your PIC application as RS232 and tell those who need USB to buy this http://www.byterunner.com/byterunner...ct_match=exact. It's inexpensive, it works and it eliminates the need for you to rewrite your PIC application, learning to use USB, .NET, etc.

I'm using 18f2550, PBP and Visual Basic Express 2008 without any problem... With the usage of bootloader you can also programm your pic in a few seconds on your circuit over USB...
