"Once the Haunted USB cable is plugged into a computer ... it begins to randomly turn on CapsLock, Insert, and NumLock modes. It also randomly inserts a Space, Backspace, Tab, or Delete.
"It does this at random times, waiting up to 30 minutes between each random event."

More of the same:
Stealth USB CapsLocker (http://macetech.com/blog/?q=node/46)
This device plugs into a USB port and implements a USB HID keyboard. Instead of doing anything useful, it waits between 30 seconds and 8 minutes and sends the scancode for the Caps Lock key. This will toggle the Caps Lock status on or off. Since the operating system controls the LED on the keyboard, the Caps Lock light also toggles. This makes it appear the user has accidentally pressed the Caps Lock key...until it happens 20 or 30 times and they get suspicious.

oh, by the way, I've been ignoring the USB controller thread. have they mentioned this :

USnooBie makes V-USB based USB devices using AVR microcontrollers, great for making keyboards, mice, joysticks, gamepads, and other neat gadgets.
