Do you know what writing to a hiddev is suposed to do? Can you, for example, 
just write a regular byte stream to it? If so, then I can tell you how to do a 
regular Alva write and we can see if that works.

Is /dev/usb/hiddev0 a device in its own right or is it a symlink to somewhere 
else?

If the device is found via searching usbfs, do you know how to then translate 
that to the right hiddev device to open or can the usbfs device be opened and 
read?

All the same size and equally spaced?

Are these keys below the routing keys or above them?

Do there seem to be any limitations regarding which keys can be pressed 
together?
