Hello.

I have bought a Acer WMR headset and I followed the instructions to use it with Slicer extension. It was working very fine in the last days. But today my headset does not leave a " sleep mode". When I try to use it at Slicer extension the headset remains black. Does anyone had that problem before?

My first obvious question is whether you tried restarting the computer. Maybe try plugging it in a different USB slot.

My second obvious question is whether your cable is intact. I’m talking out of experience, my cat chewed through 3 cables…
