    Default Re: What a Pain In The USB-utt

    Here is some code in this link that looks like it will work for the USBDeviceState initialization.

    Also, here is some information on the keyboard receiving information from the PC. The PC tells the keyboard when to turn on the NumLock, CapLock, and ScrollLock LED.

    I've seen another thread where someone was able to demonstrate "stealing" information from a PC a few bits at a time using the NumLock, CapLock, and ScrollLock signals. The sensitive information was sent back through the keyboard device and recorded on a microcontroller USB board.
