According to the usb device descriptors it's a USB HID device. That's basically
everything I know. Once I discovered libusb doesn't seem to support USB HID very
well, I didn't investigate much further due to a lack of time.

I wouldn't be surprised if the high level communication protocol is still the
same as the other Uwatec devices. For the Meridian Scubapro/Uwatec also switched
only the low-level layer from IrDA to usb-serial, and kept everything else the
same. But of course that's just an educated guess, and I could be complete wrong.
