I read on a website that if you turned your computer off, unplugged it and left it for a minute or so it would reset something and that did work, for a day, but its just started doing it again.
In general the PC felt like it was running pretty slow and always just about to freeze/crash.
I had a keyboard and mouse plugged in to the front which allowed me to access this.ĭisabling it / re-enabling it tended to cause my PC to freeze having to hard restart it, as did scanning for hardware changes etc. I restarted a few times and that would fix it briefly (some of the time-, the PC wouldn't boot up at all and would be stuck on the Motherboard loading screen much of the time) and after many frustrating hours managed to narrow it down to the 'VIA USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)' in device manager not working. Having the second screen always seems like something I'll want but never actually use.Īnyway, thanks for posting, Tazzik.This problem appeared out of the blue yesterday, was in the middle of working and suddenly I heard the sound of unplugging a mouse/keyboard and everything plugged in to the PC (USB ports) stopped working.
Did you also try just disabling the laptop display, without disabling the device? I might try that, since Windows will remember and automatically make that change when I dock/undock.
Format Description: Dell Update Packages (DUP) in Microsoft Windows 32bit format have been designed to run on Microsoft Windows 64bit Operating Systems. File Name: ASMedia-USB-eXtensible-Host-Controller-Driver68PNMWIN1.16.61.1A17.EXE. Perhaps the device switching could be scripted somehow. File Format: Update Package for MS Windows 32-Bit. I went to the device manager and found a yellow triangle before Intel USB 3.0 eXtensible Host Controller. There was no power in either of the USB 3.0 ports.
Either Windows not working the way it should or one (or both) of the Intel or Nvidia drivers, I guess.Īssuming this is a proper workaround, the remaining question for me is which is more hassle: disabling/enabling this driver when I dock/undock, or connecting/disconnecting one or two more USB cables. (This usually happens when the laptop heats up too much, not a big deal.) When I turned on the laptop, the two USB 3.0 ports stopped working. (Like you, it seemed to depend on the app - I did a bunch of typing into Notepad to test some of my earlier attempts and it didn't happen there.) This workaround would have interesting implications for who/what/where is culpable, though I'm not sure exactly what they are. Still, it seems to work for me, too! I haven't encountered a keyboard issue typing this long-winded reply, although Chrome is one of the apps where I encountered problems before. I had hoped to keep that chip available for things like PhysX, even though apparently my Vive space is 10cm too small for Nvidia Funhouse.
It's just "Inactive" according to Nvidia GPU Activity tool, because there's nothing on that display that'd trigger Optimus to switch. Is this what you see as well?Īlso of note, my 970M is still enabled in Device Manager. For one thing, when I disable the Intel HD Graphics, my laptop display still works! Windows thinks it's connected to a "Microsoft Basic Display Driver" adapter. Do you have any more details, because I see unexpected behavior when I try that. (FWIW I also tried the old chestnut of disabling power management on the various USB hubs serving the keyboard, but no luck.)
On the bright side, the more I learn about it, the more it starts to seem like something that can be fixed in software - either drivers or firmware - rather than something that would require a hardware replacement. Make sure your laptop is in an available network environment, then connect to internet because it is an online update process. Tip: The device name may vary by different models. Is it the USB 3.1 controller driver (a generic Microsoft driver right now, and I don't see others from Intel)? Is it the Thunderbolt driver (Intel has newer ones here than what came with my Blade, which work but don't fix this problem)? Is it Core firmware not properly managing signaling between the graphics card and the USB controller? Something between the keyboard and operating system is sometimes delaying USB signals, but which of the many items in the chain is it? I can't tell. USB 3.1 eXtensible Host Controller 1.10 (Microsoft)(4) and select Update driver(5). This still doesn't exactly tell us where the problems are. (The ethernet is provided by a USB ethernet controller hanging off that.) (TB3 also has a separate USB channel on other pins, but it's USB 2.0.) In Device Manager I can see the device connections fork, with an "Intel USB 3.1 eXtensible Host Controller" as a sibling to my GTX 1080 card. It looks like the main 40Gbps TB3 channel is used for both PCIe graphics and the Core's USB ports and ethernet.
