opentrack now has a standalone driver for the PS3 Eye, and you don't have to pay for (or pirate, for that matter) the CL Eye driver that's buggy, slow, unmaintained and broken with every other Windows 10 update.

1. Open the Windows Device Manager.

   • 

2. Uninstall any existing closed-source driver.

   • 

3. Install the libusbK development kit^[original].

   • 

4. Install the libusb inf wizard^[original].

   • 
   • 
   • 

5. The open driver should now become available in opentrack.

I am using libusb driver and my camera started having this error all of a sudden. I changed the USB port but it did not work. I also tried to reset libusb driver to no avail. This is how I fixed it (from https://github.com/opentrack/opentrack/issues/1495#issuecomment-1772758557):

Open device manager
Scroll to Universal Serial Bus Controllers
See if there is any unrecognized device and uninstall it

To use the camera and the microphone at the same time you might need to use the libusbK driver instead (available in the same installer).
