USB + CHSARP Reference

P: n/a
I am trying to find online some decent tutorials about being able to command
and control a USB port through a C# application.

I have done some minor RS232 work back in the VB6 days and would like to
experiment to see where the technology has gone with USB.

Any links or reference would be greatly appreciated.

Thanks
Jay

USB is a completely different ballgame to RS232. You will need to know what
it is you want to do from the outset, to see if there are any classes
already out there that can be used. For example, you may be able to save
yourself a whole load of work writing USB stacks and use something like the
HID that already come as part of windows.

If you want to use USB for more general interfacing, consider something like
the devices these guys http://www.ftdichip.com/ sell. They are so low cost,
it's not worth the time developing your own driver and customising a micro.
Just use their off the shelf device, which as a mature driver, and if you
ask them, they will even let you have a unique product ID (PID) -saving you
having to pay the USB group a shed load of money each year.

The driver even has functions to emulate the old RS232 port.

HTH.
