I think you can do this with usbhidaction(1). Like I mentioned earlier,
try using usbhidctl -f /dev/uhid0 -r to see what sort of features the
device reports. It sounds like it just has some buttons. You can use
usbhidaction(1) to have the buttons perform specific actions when activated.
You just need to create a config file and launch usbhidaction at system
startup. This should be fairly easy to do for the volume controls at
least: I'm not sure how to use usbhidaction to emulate keyboard presses.

I don't think so. It's convenient to make USB keyboards and mice appear
to work just like legacy keyboards and mice.

Something tells me this isn't the case. It's possible for a single USB
device to have multiple interfaces, but bear in mind that you have to
be able to use both the keyboard and mouse at the same time. For that, you
would need two separate device instances, not one device whose personality
can be toggled back and forth between keyboard mode and mouse mode.
Once again, we need to know what usbdevs -v and usbhidctl have to say
before we can speculate further.
