Programming .Net to use USB device?

    Ok, this is a where to start. I'm toying with the idea of creating a little electronics project, with LEDs, that would be controled using the computer and a USB cable. I've seen things like this done with the older serial connection. VS 2005 exposes a serial port control. I haven't dug to deep yet, but was wondering where to start. What would I need and what would I look for.

    I would bread-board the project first of course. I don't think I would have on-board memory, but have the device tethered through USB for functionality.

    BTW, what is the maximum length for USB cables? Where can I find some specs for the USB standard.

    Check out the August 2006 issue of Circuit Cellar magazine. Great introduction to building USB devices. In short, your usb device will need two main compenents: a usb interface chip and a microcontroller. In the article the author uses a Maxim usb transceiver with a SPI interace to the microcontroller.

    When in doubt, there's always for complete specs for the usb standard.

    I haven't really used this, but it might work (for the software part of the project, of course:))-

    Ive built a simple  USB interface library based on the SharpUSB code.

    add me to MSN if you like and I can send some code over and help you out.
