Description

While running make, I am getting this error. I tried installing hid using pip but it does not help.

Linux Ubuntu 20.

On which OS does the problem happen?

Linux

Hi, @sirshurf. hidapi isn't installed. Try apt-get install build-essential git cmake libhidapi-dev

[sirshurf]

Yep

libhidapi-dev is already the newest version (0.9.0+dfsg-1).

@sirshurf, idk if that is the problem, but audeze_maxwell.c is including the hidapi header with #include "hidapi.h" instead of #include <hidapi.h> I've fixed it in a fork, could you test it, please? https://github.com/ModoloDev/HeadsetControl/tree/bb9625034d340c2849b9a48fbe543f30ffd3f18d

Nope

Same, I used your link git clone https://github.com/ModoloDev/HeadsetControl.git && cd HeadsetControl And this is what I got.

Yep

libhidapi-dev is already the newest version (0.9.0+dfsg-1).

Oh, I see what’s happening. The latest versions isn't 0.9.0, it's 0.15.0 hid_get_input_report was implemented in 0.10.0

[sirshurf]

That means the support is only for Ubuntu 22 and up. https://launchpad.net/ubuntu/+source/hidapi
