Guys, have you noticed how similar this idea is to the often-derided

flash key plugged into a USB<->PS/2 converter? That's a great thing! It means we'll attract all sorts of crazy hardware hackers.
I've never heard of anyone doing that? I'd be curious if you have any links?
Short version: Some keyboards are dual USB+PS/2 keyboards and have an USB connector by default. They often come with a pure passive adapter which will convert the USB pinout to a PS/2 pinout. http://us.st12.yimg.com/us.st.yimg.com/I/directron_2019_60686738 is an example image of such a female USB -> male PS/2 adapter. Of course, this will only work with devices supporting the PS/2 protocol natively.
Right.
Some time ago, a few pranksters (myself included) suggested to use such an adapter to plug USB flash drives into legacy PCs without USB ports. Of course that wouldn't work due to the passive nature of the adapter (electrical and protocol mismatch).
Carl-Daniel you prankster :-) Suprised if the fool that tried it didn't brick their flash drive. I thought you meant some hardware hacker had actually acomplished this. Now that would be sight to see :-)
The PS/2 port is generally seen as a pure input "device" and using it for complex output (i.e. not just switching keyboard lights) will certainly baffle lots of people and confuse those "of course that won't work" experts.
Agreed. Now we just need to figure out what kind of hardware to convert the DATA & CLK lines to serial.
