To Whom it may concern:

My company manufactures and designed a patented ruggedzied USB game style controller for various industrial, military and aerospace purposes. This is a product that has been in production for ten years and has a glorious track record with thousands of units built and sold worldwide. It supports all versions of windows, and also linux, RHEL, Android and etc. without issue.

One of our customers is trying to integrate it into your unity platform but with difficulty.
Below, I’ve provided the crash report which was forwarded to me

If you have any suggestion to offer it would be most honestly appreciated.

I think this is the essence of the issue here. A developer familiar with this code might be able to shed some light on reason for the error. I’ve posted this as of more than two days ago to no avail. I believe it’s an issue with the HID report, something that is unfamiliar or not supported.

It might be worth mentioning that this control stick outputs deflection travel as signed char which is 8 bit 2’s compliment data. Most controllers output this as signed short in a.k.a 16 bits wide. Could this be an issue?
