Resolved Question

USB devices temporarily lose power after startup

May 12, 2017 6:40AM PDT

I'm having a problem with USB devices being disconnected/turned off when my computer initially starts up. I have a USB headset, USB keyboard, and USB mouse, and when I turn on my computer and log into Windows, all of them will entirely stop working several times during the first couple of minutes after startup. All of the devices completely lose power and will not work for a few seconds, and then they'll start working again, and this will happen maybe five times or so. This happens whether I'm using the case's front ports or the motherboard's built-in ports, and whether I'm using USB 3.0 or 2.0.

Windows is up-to-date, I have my motherboard's BIOS updated, and I have Adaware Antivirus, which scans my system once a week and has real-time protection on. I've not been able to isolate what causes it other than that it happens only when my computer first starts up; after a few minutes of this, everything works properly and the devices never shut off again.

Any ideas what could cause this? Below are my system's specs. Any help would be greatly appreciated.

Windows 10 Home 64-bit
Intel Core i5 6600K
ASUS B150M-A/M.2
16 GB DDR4 RAM
MSI Radeon RX 480 8GB
Kingston 120 GB SSD (Windows installed here)
Seagate 1 TB HDD
Hitachi 500 GB HDD

The real problem.

Is not the power up and boot areas but later when the USB device stop working.

So I'd check that the BIOS is current and the builder installed the drivers the motherboard maker has at their web site. I'm finding new PC builders trying to just install Windows 10 and failing to get it working.

Drivers were the issue

I had the MB BIOS up-to-date, but apparently not all of the other drivers were. I downloaded everything from ASUS's website, and it looks like that took care of the problem. I feel like I should've figured that one out on my own, but I just didn't ever check anything other than the BIOS.

Thanks much. Happy Now everything stays on all the time, like it's supposed to.

Good to read.

Just for everyone's sake, here's my rundown on a clean install.

1. Current BIOS. Now is the time to do this since I don't want to do this often.
2. Clean install Windows. Plenty of articles about that so next.
3. If everything works then you have a choice of going with that but usually I need motherboard then audio, video, network and other device drivers to finish the job.

The drivers that come with Windows are generic and after you do this a few dozen times you find which drivers to seek out and be ready to feed the machine. But not everything needs a driver as you'll learn. Example? I've never had to find a driver for the Optical DIsc Drive (ODD) but have for the motherboard a lot of times.

Same here.

I thought that is how it works on many PCs. That is, most PCs use power management so the USB power can be turned off and on in the driver. I'm not convinced this is a bug.

Still an issue

Once my computer starts up, I shouldn't have my devices turn off, for power management or anything else. I can be in the middle of typing an email or starting to open a program, and then my mouse shuts off or my keyboard shuts off, and I have to wait five or ten seconds until it starts working again. That shouldn't happen. Regardless, I just now disabled the "USB selective suspend setting," so I'll see if that makes any difference.

"Once my computer starts up, I shouldn't have my devices turn off,"

Then you'll have to deal with the maker of the motherboard and who wrote the drivers.

Remember I take it you know to have a current BIOS and the maker's latest drivers (from the motherboard maker.)

If this fails, then the board is defective, try another if the maker does not offer a fix.

Look in device manager at your usb devices and usb hubs.

Check the power management setting.
