I like that you got a USB keyboard hooked up to your Prime in another video. The HobbyTronics USB Host Controller Board looks to most excellent and well priced too.

I have found out since making that, that you can just plug a keyboard directly into the HP Prime with an OTG cable. It will be visible with USBOpen(), entering that will give the connection details, then the next time you use the details it gave you USBOpen(8425,43288) e.g. will connect it. Then USBRecv() will get the keyboards method of displaying the different keys.
