For example, the Linux input event system does not allow more than 64 absolute axes, and only half of those axes are even defined.
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 so.
[hid] aims to support that spec, not every input possibility under the sun, but I think it can work for you without too much hassle.
All our plans about using sending axes values through USB involve the MultIO and only the MultIO.
It seems to me that you are saying that I should tailor [hid] to work for every single input possibility.
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.
That would greatly impair the usability for almost everyone else who is going to use it.
It could default to "mode name" so that the default behaviour of [hid] is like the old behaviour of [hid].
What you are trying to do with your array of sensors is barely in the realm of USB HID. This is not defined by me, this was defined by the USB organization.
I'm sorry for wanting more.
USB HID is about mice, joysticks, tablets, gamepads, etc. There is no USB device type "64 range finders in a row". The USB HID spec is a perfect example of design by company getting their little piece custom piece in.
I'm sorry for my misconceptions.
