Re: new/cool USB footcontrollers?

Coincidence... I was just emailing William Walker about this at this very moment : the Little Giant is not USB-powered unfortunately. I'll just copy-and-paste what I was explaining to Bill :
Main problem is that with the high brightness LEDs the LG draws more current than what's allowed for a low-power USB device. The USB protocol allows me to define the LG as a "high power" device which can draw up to 500mA, but that would require the LG to go into some kind of power saving mode (dimming all LEDs) whenever you try to plug in the USB cable, and only go back to full power after the PC has recognized the hardware correctly. My first prototype was USB powered, without all this logic implemented, so I fried the internal USB ports of my laptop, making it pretty unusable... that's when I decided using USB power was not a bright idea for the LittleGiant.... ;-)

It was entirely powered by the USB bus, and fed MIDI data to the computer via USB.

This one was on the LD recently:

uses midi phantom power, not usb though.
