I’ve a particular HID device whose support/operation is lacking using the normal HID driver, basically it won’t deliver certain reports (that the driver can’t identify from parsing the descriptor..).
However, I know exactly how to control and listen to it via sniffing the traffic.
It should be straightforward for me to write a userland usb driver, but how in these 10.13+ days do we tell the original HID driver to stop taking control of it?
I believe in the past it was a matter of a codeless kext, and presumably I’d also have to disable SIP (or do they hand out certs for this usage?).
Are there any ‘nicer’ ways of blacklisting a particular device from the HID driver, or some other approach that would be better?
ps, likely incoming apple bug report once I better determine how the HID driver is failing, specifically why the descriptor looks truncated.
