This is why I asked Christian Klippel to change the Multio so that it also
works as a non-HID device. This way I just have to code my own [multio]
object using libusb-for-Ruby (another part of GridFlow).
Originally Christian was instead recommending to apply a patch to the
kernel source, but I think most users are too lazy to compile their own
kernel -- at least I know I haven't been willing to do so since 2000 or

All our plans about using sending axes values through USB involve the
MultIO and only the MultIO.

I am not forcing you :) but I think it's an easy feature to support. I
mean, you really don't have to pick one model or the other: that's a
false-dichotomy. It's not an either-or situation. I suggest that you
implement it this way:
You could make every event message carry both the sensor-name and the
sensor-number. Or maybe sending a "mode number" mode could switch to
number mode and allow "mode name" to switch back to name (symbol) mode.

It could default to "mode name" so that the default behaviour of [hid] is
like the old behaviour of [hid].

I'm sorry for wanting more.

I'm sorry for my misconceptions.
