Can't use more than 2 trackers (Vive)

[lil fang]

I have a Rift S.
Using 1.0 Base station (Only 1 right now)
With 3 3.0 vive trackers.
I got them working for a few minutes and played with them and now they started having problems.
My 3rd tracker just keeps not detecting.
I tried switching between all 3. There's no problem with a specific tracker, but every time it's another one that won't get detected. I tried different usb ports.

You say you tried different USB ports, but hear me out anyway. A classic problem with Vive Trackers is that the dongles won't work if more than two are attached to the same USB host. This can be hard to figure out as your motherboard could have various clusters belonging to the same host or not. Best is to try a few different ports indeed. I would experiment more with that.
