USB programming

Question

I want to program a microcontroller (AVR) to control some leds through USB. It\'s just out of interest in how to build and program USB devices. There are some AVR microcontrolle

Answer 1

One good way to go is just to develop a HID device, since the driver is built in to most higher level OSes and pretty flexible for simple IO like you are talking about. Another good option is just using a USB RS232 device or software. I use PICs which have a number of nice devices with USB onboard.
