If they are you can just go to the dell website and find the correct drivers. Came here myself via google search and was able to accomplish what I needed in both methods I listed above.I now have managed to get win 7 installed by ingesting the USB 3 driver in the win 7 boot usb. These hubs may unfortunately not be restarted without a reboot. Some USB ports may report restart required. Sorry Forum removes them in the post so I can't type them literally. Remove parenthesis and use actual symbol for Asterisk.
Type devcon.exe restart (Asterisk)root_hub(Asterisk). Browse to the devcon.exe location in command prompt.Įxample: cd Program Files (x86)\Windows Kits\10\Tools\圆4 (varies on windows kit you installed for path as well as x86 vs 圆4 bit windows machines).

I think that it's a good idea to save your work if possible before hibernating the computer. Obviously, this method might only work for a laptop rather than a desktop PC, and if you're having the same problem re-occur every few minutes then it would not be very practical, but for anyone having this happen only occasionally then this might be a viable workaround. I have not tried this method by choosing to simply enter "Sleep" mode rather than "Hibernate" mode when pressing the power button, but when I've left the laptop inactive for many hours it makes no difference to the problem. Be sure to stay in hibernation mode for long enough that the devices power off (lights on keyboard/mouse turn off, etc.) When you wake up the laptop again the USB ports may be functioning properly again. Next time you have the problem you can then press the power button on your laptop (if plugged in or on battery, depending on settings) and enter Hybernation mode. 
The only workaround solution I found that worked, other than turning the computer off and on again, was to change my laptop's power setting to "hibernate" rather than "sleep" when I pressed the laptop's power button, and then going into and back out of Hibernation mode.Ĭlick on the "Windows" button > mouse and/or keyboard lighting up but suddenly not functioning, when plugged into a particular USB port. I'm not very computer knowledgeable, but I was having a similar problem with USB devices occasionally malfunctioning by receiving power but not working: e.g.
