Error Code S0012261-101
I've tried hooking our Acer MR headset to every computer we have, including several gaming laptops (alienware, razer blade, MSI, and Asus) and I get the exact same error code in the Mixed Reality Portal on every single one.
I can't find any documentation with the error codes so I don't even know where to begin trying to diagnose the problem. Any help y'all can provide would be much appreciated.
