As per our PM's I have been unable to mail you direct the info so have a link and some demo programs here to show you how easy USB is in Basic.
I have to point out that I don't program any more in Pbpro but the USB commands should be simular. Although I note that you can only send an array in Pbpro not variables on there own and you don't have direct access to the USB buffer. I can use it as a String for my own code. Apart from that and a few other differences e.g. the lack of Auto option you will find it very interesting reading.
The info is at the back under USBPOLL, USBIN and USBOUT. Down load the info Here
Also find some basic demo code
