[GTALUG] Emulating a USB keyboard using ???

[William Park]

Hi guys,

Do you know a way to emulate a USB keyboard using Raspberry Pi,
BeagleBone Black, ODROID, or some other embedded board?  That is, as far
as PC is concerned, it's receiving keypresses from some keyboard.

I know those boards have UART pins.  But, even if I connect the pins to
a serial-to-USB cable, the USB end of the cable will show up as serial
(/dev/ttyUSBx) and not as keyboard.  I have such a cable, and that's
what I see.
