have my Vive since february and it worked flawlessly ever since.
Of course I did not change a single thing (really!) but when I tried again two weeks ago I got the error 108 "not connected".
I tried everything suggested:
Removed USB drivers
Tried every USB port (2.0 and 3.0)
Connect the Vive directly without linkbox
=> no result
I sent the Vive and linkbox in and got it replaced by HTC (really fast in 4 days including shipping time, thanks!)
I even got new 3-in-1-cables
But the error persists, only for >three< minutes I got the Vive working again.
I assume a problem with USB. Depending on the port I connect, I get several error messages from Windows: "USB 2.0 MTT-Hub device removed", "unknown USB device not installed" or similar.
I just installed a new Inateck USB-expansion-card with Fresco chipset. Installation was successfully as instructed in the manual as I have two new devices in device manager:
"Fresco Logic xHCI (USB3) Controller FL1100 Series"
"Fresco Logix xHCI (USB3) Root Hub"
I also replaced the USB-cable from PC to linkbox with a new one.
This is what happens when I connect the linkbox with power and USB to the new USB-ports and after I start Steam VR:
Windows prompt: (translated from German so maybe not exact wording)
"Installing new devices...
The device software was not installed:
Fresco Logic xHCI (USB3) Hub Device removed"
What can I do? Desperately seeking for help! Thank you!
Solved! Go to Solution.

Have you tried removing SteamVR/Vive USB drivers yet? This may help you: https://support.steampowered.com/kb_article.php?s=6643267c2b51f08c93e8fc35bf35aa48&ref=2748-WEIK-956...

Am I understanding correctly that you had sent in your HMD for repair/replacement? If so, could you PM me your ticket number so I can see what was done. Thanks!

Well, maybe. I got the HMD and linkbox back from support. The HMD was with protections on the glasses again, cable, headstrap and skin protection packed separately , so I think it might be a new/refurbished one. The linkbox I can't tell, could or could not be the same.
Could the linkbox be (still) broken? I connected the linkbox to a different PC/notebook in our home and when connected you can hear the distinctive Windows-sound when you plug in an USB-device several times. But right after that you hear the sound for un-plugging. And again for plugging/unplugging...continues endlessly.

Can you provide specs for both your PCs?
10-27-2017 10:54 AM
Main PC (for Vive):
Mainboard Asus Z-97P (latest BIOS), 32 GB RAM
Asus Strix Gtx970, 4GB
Windows 7 Prof. 64 Bit, all Updates
Inateck KTU30FR-202I USB-Card
Intel Core i5, 8 GB RAM
Windows 8.1 Home 64 Bit

I think we can probably rule the linkbox out since you tried to bypass it and that was no good. This is kind of a long shot, but have you connected your power directly to the HMD bypassing the linkbox? I know normally we just bypass the HMD and USB but maybe try the power and see what happens?
I am still suspicious of the USB, so maybe we should try USBDeview again after we've done all of this, that almost always solves USB issues. The Inateck card is up to date on drivers as well, I trust?

Yes I think the linkbox can be sorted out, too. I contacted HTC Germany last weeek to ask about the linkbox but did not get an answer yet. There are public holidays in Germany until Thursday, so it might take a while but as mentioned the linkbox should not be the problem.
I directly connected the Vive via 3-in-1 cable to the PC (no linkbox used) and used the separate power. Windows tried to install USB-devices:
Translated: first entry: can be used, second entry: device removed.
Maybe we should try USBDEVIEW? Thank you!

I think USBDeview is a very good idea at this point. Try that and report back your findings.

I tried USB Deview but could not find any entries with vendor ID 28de or OBB4 (of course I checked "display unconnected devices" but I uninstalled several drivers with vendor ID 0000 and named bad_device or similar.
I reconnected the linkbox and two devices were insalled (it should have been at least four, I think?). See picture below. But error 108 and the red blinking light persists.
I am really sad because I do not know what to do else... You think we can get this working again?

Next try. Is there a downloadlink for the correct USB-drivers for Windows 7 64 Bit so that I can manually install them?
11-01-2017 10:08 AM
I can find out. Question: Are you connecting to the USB 2.0 ports or the USB 3.0 ports? Try to use only USB 2.0 and see if that works.

Did you have any success in locating any Win 7-drivers? I do not want to push but as it seems I have a pile of sophisticated yet useless scrap here...
