I'm on driver version 411.70 - I'll have to update and try again tomorrow. I've tried a couple SteamVR reinstalls and quite a few USB driver reinstalls. I'm more and more suspecting it's something with the devices / drivers Vive Wireless creates when it starts up. On my clean install, the camera and speakers show up in Device Manager. On my existing install, there is a sound device and usb input device that claim they have no drivers installed, aren't named correctly (Displaylink audio device instead of HTC Vive), but otherwise don't show any errors, and won't let me manually install drivers from C:/Program Files/Displaylink XR/drivers. I'd still like to find the cause, I'm a tad concerned with a fresh install that I'll end up recreating whatever problem scenario exists and being back at square 1.

I tried a clean Windows 10 install, and it actually worked. I used a spare drive (you can also shrink a volume and create a new partition on an existing drive.) I only installed motherboard drivers, nvidia drivers, Steam, Steam VR, Beat Saber, and Vive Wireless. I'd suggest trying similarly - don't wipe your existing drives, just do a minimalist test run. I still want to try a few more things before I give in and do a clean install "for realsies".

Agreed, it's not an ideal solution, but possibly worth trying. I'm in a similar boat. The next thing I'll be trying is a fresh Windows 10 install on a spare drive. Just to see if it makes a difference. (Shouldn't need to authenticate the OS, even -- just a bare minimum trial.)

Hey there I've read a couple posts where upgrading to Windows 10 worked for missing drivers.

I tried switching to Direct Mode, Extended, and back -- no such luck. I also switched the PCI card to a PCIe3 x4 slot, removing the SSD and disabling the second graphics card in case it was some PCI bandwidth issue. The logs still look rather similar. Not sure if these are of any relevance, or expected: I see this under "Devices" in the SteamVR system report. It calls it an Unknown Tracked Device. Device 2 - Unknown Tracked Device Class DisplayLink_USB_6101-430Z187L03760Device Path: /devices/displaylink/DisplayLink_USB_6101-430Z187L03Best Alias: Invalid In the room overview, the "unknown device" is there, but there are no bounds to be seen. The logs mention not finding any lighthouse devices. Driver lighthouse has no suitable devices. (But the lighthouse drivers are there, and USB "Watchman Dongle" devices show in the list of USB devices) No 3rd party accessories. Using the short cables that came with the wireless adapter. Thanks for the reply, appreciate the ideas.

I've got the wireless adapter. Vive Wireless connects to the headset fine, but SteamVR gives error 108 - Headset not detected. Switching back to wired (link box) works fine. Placing my hand in front of the transmitter shows less bars of connectivity. Graphics drivers are updated, Windows is updated, I've re-installed SteamVR and Vive wireless. Intel 6700K, GTX 1080 (SLI), Windows 10 The PCIe card is in a PCIe2 x1 slot. It's less than convenient, but I have a PCIe3 x4 slot I have not tried yet. I will try it tomorrow. Otherwise, I'm out of ideas, and posting here in hopes someone else has another suggestion. SteamVR raw log files can be found here - https://pastebin.com/PSqrmPzi I've cut out a fair chunk of redundant or old info to fit the pastebin size limit. I've also got some screenshots, showing Vive Wireless, SteamVR, and USB info.
