I doubt that it has USB host built in, and last I checked two USB-slave devices don't talk too well with each other with no usb host device present.
All is not lost, however, because I'm sure someone will figure out a way to hook up a similar keyboard to some of the GPIO pins on the EXT port. I doubt they can emulate a USB protocol, (or it would be difficult to do), but I'm sure someone can modify one of the GP32 chatboards, as I believe they were serial, or a similar protocol.
having a keyboard would be cool for certain types of apps, although I probably wouldn't use if everyday. Anyone working on this yet? :blink:
