Anyone know of a simple device that's operated purely over the control
channel? Possibly in write-only mode? Perhaps something as simple as a
light or LED that can switch on or off.
I'd like to be able to show some sort of demo of this stuff relatively
early with just the UsbDevice class without having to first introduce
UsbConfiguration, UsbInterface, UsbEndpoint, and finally UsbPipe. By the
time I work my way through all that, I'm afraid my audience will have
departed for dreamland if I haven't actually shown them a simple working
program that accomplishes something.
Possibly I could even hook up such a device myself, but I'm not a
hardware person by training, so I'd be more comfortable with a
prepackaged solution that doesn't require me to read circuit diagrams. :-)
