(Kind of) [solved] Oculus Rift DK2 won't turn on.

Just posting this here so that it may help others:

So, after working fine for a couple of weeks, I did something I don't recall, and now my DK2 looks bricked. There's a windows sound when I plug it in, but no LEDs will turn on, and the Rift seems completely dead.

My solution, which has already worked a couple of times, is the following:

In the windows device manager, look for any USB devices with the hardware manufacturer id of 2833. Pay special attention to "USB Input Device", "USB Composite Device" and/or "Generic USB Hub".

You can check the USB IDs by right-clicking on the device, properties, details, select "Hardware Ids" from the select box. The number after "VID_" is the vendor id.

Right click an uninstall all of these devices.

Then, uninstall the oculus runtime, and both oculus drivers (camera and display).

Then, power off your computer. With the computer powered off, unplug the rift's and the camera's USB cables, and plug them into other ports. Try to avoid usb3 ports. Try to change the internal USB root hub they are connected to - i.e. try to change the "group" of USB ports they are connected to on the motherboard.

Now power on your computer. With a bit of luck, your DK2 should at least power on now.

Then, re install the oculus runtime, and you should be set.

The problem seems to be caused by power issues - my guess is that sometimes the Rift doesn't get enough power to power up all its subsystems, so windows detects just the USB infrastructure subdevices (built in hub, input device, etc), and windows will assign its generic drivers to them, and they stick and override Oculus' drivers.

Very annoying.

Now I just have to get the darn camera to recognize my head movement again, but that seems to be another issue.
