SteamVR & Vive Errors 306, 307, 405

Bit of a grumbly post this morning.

Graev just got the Playstation VR and gifted me his HTC Vive — which you may recall I blogged about some time ago. I was super excited to bring it home and get it all working so that Graev and I could play Star Trek Bridge Crew.

I brought it home, hooked it all up the same way we hooked it up at Graev’s place, and was met with brutal disappointment. It wasn’t working.

“Error: SharedIPC Compositor Invalid Connect Response (307)”

That’s the error I was receiving in SteamVR.

Everything was green. All items were detected: headset, both hand controllers, both sensors. Yet for some reason I was getting the 307 error on Steam, and in the SteamVR little window in the bottom center I had a “A key component of SteamVR isn’t working (306).”

I proceeded to spend the next 3 hours unplugging and replugging, rebooting, resetting, uninstalling, reinstalling, swapping cables. Nothing.


Fast forward to the next evening. I have a long day 12 hour work day and finally have time to play so I cross my fingers and run into all of the same errors.

This time Graev recommends I try putting SteamVR into beta mode. Done.

Now I get error 405 – Compositor can’t create graphical device. For hours it appeared I was the only one on the planet getting these errors and that nothing was going to fix my problem. Then 12 hours ago (aka last night when I was in the thick of things) it looks like another poor soul has my same issue.

I’m going to try doing display port to hdmi for my monitor and see if hdmi to the link box fixes my issue. If that still yields no success, I’ll be giving the Vive back to Graev and giving up. I can’t waste 3 precious nights of gaming time futsing around with gimmicky VR crap that doesn’t work right out of the box.

Seriously, it’s 2017 and you release a product that doesn’t work out of the box? As a consumer, I have no patience for this type of experience — strike that, I have 3 days worth of patience and now a whole ton of bad will.

Update: Fixed for Vive and SteamVR errors 305, 306, and 405!

I tried swapping cables and having my monior being on the display port with my Vive Linkbox using hdmi but that didn’t work. You can see a bunch of my solutions above. None of those worked.

What ultimately worked and solved my issues with the Vive error 306, 306, and 405 was rolling back my Nvidia drivers. Huh? Wtf? I know. That’s exactly what I thought.

I rolled my drivers back to version 381.89. I did a clean installation of my drivers. Just to be safe I went to the standard windows program removal and removed the drivers there. Then I used the install utility (what I linked) to do a “clean installation” of the 381.89 drivers. I left the Nvidia experience and audio drivers alone but clean installed the 3d and other drivers back to 381.89 or whatever version came with these older drivers.

Then I restarted my computer. While off, I unplugged all of the cables for the Vive.

I booted the computer back up and plugged my cables into the linkbox in the following order (I have no idea if it matters): USB, power cable, HDMI (or mini display port — I tried both ultimately and they both work).

Then I plugged in the Vive headset in the same order.

I booted up Steam, then SteamVR.

To my complete shock, it freaking worked.

And it wasn’t even the latest Nvidia drivers causing the issues. I had a few versions BEFORE the latest version. It didn’t work with those, it didn’t work with the newest. I only worked when I used Nvidia drivers 381.89. Also, note that I am using the BETA version of SteamVR that you can use by right clicking on SteamVR in your tools library and going to properties and enabling it there.

I hope this helps you solve your problem! May you struggle less than I did.
