Hi,
looks like nobody has profound knowledge about that display so I'll
hazard a few guesses.

You can try the LCDproc-drivers that support USB-devices too, but I
doubt one of them will work.

The 2 files look like it is a HID-device so the kernel-HID-drivers may
bring some results. I would start trying with the keyboard-driver maybe
you are able to use the keys with it. (Is there something like a
standard HID-display USB-IP-phones often have displays?)

If it is not a HID-device or the kernel-driver isn't working the
manufacturer is the last chance. If you're lucky they provide a driver
or at least the informations to write it.

Good luck,
Stefan
