Hi,Thanks for your interest in my little problem here. So let me go into more detail about the history behind this in that this all started when I noticed that 'Unrecognized usb device' error in device manager.Upon further investigation I found that it would only show up when the Z270-WS PCIEX4 slot was set to 2X operation from with in bios. However turning on 2X PCIEX4 mode has a side effect of causingthe system to triple boot or turn on and off 3-4 times from a cold start. So either I run my PCIEX4 slot at 4X mode and give up the front panel USB 3.1 Asmedia controller or operate the PCIEX4 slot at 2Xmode and have both running at the same time. I did a lot of trial and error and tested each usb port out to make sure that it works appropriately and in fact each port had no issues recognizing devicesplugged into it.Anyhow I think I have narrowed it down to this Kingwin KW525-3U3CR USB Hub card reader front panel device. When I first got it I had to send it back for RMA because I thought it was producing thatUSB error and it was therefor defective. So they sent me a new one and wouldn't you know its still producing that stupid port reset failure error.

Kind of disappointing. Anyhow probably was connectedto the front panel port and of course error went away when in 4X PCIEX4 mode but this front panel device is a piece of garbage. For example there on three standard usb ports on it and the last three are controlled by a hub that only works in USB 2.0 mode and fails to recognize usb 3.0 devices but only usb 2.0 devices despite it being written each port usb 3.0! The first port has its own connection bifurcated from the usb header which operates at usb 3.0 speed no problem.As far as my system taking 3-4X to start up I ruled out every usb device by unplugging them all and it still acts that way. So I either choose to not have front panel USB 3.1 ports and have a quick startupor have all my usb ports turned on and deal with the system going on and off every time I turn it on cold. I contacted ASUS and they want me to RMA the motherboard but I think they got a bios bug going on!Thanks.

Disable usb 3.0 in BIOS can't as BIOS doesn't have that option; Disable Intel(R) USB 3.0 eXtensible Host Controller in Device Manager. Also didn't help, as it is disconnecting device fully. But some devices are working such as usb mouse. Updated power options to Disable for USB selective suspend setting. I need to disable usb 3.0 (switches all ports to 2.0.) But the option isn't showing in my bios. Is there a way to disable it in Windows?

In some rare cases, you may turn on your computer to discover that your USB ports are not reading any of the devices you plug in. Port after port, still no luck. You go into Device Manager and to your dismay -- you discover that the USB ports have been disabled!

Fortunately, there is no need to panic. It is highly unusual for every single one of the USB ports to be malfunctioning, especially on laptops and desktops where there are 4 or more USB ports. As such, the actual underlying problem may be that your USB ports have been disabled in the BIOS! For most computers, we can easily fix this by re-enabling the USB ports in the computer's BIOS menu. We will accomplish this by restoring our BIOS settings to default -- effectively setting our BIOS into a factory state. This video and written guide is specifically-applicable to HP laptops and desktops, however if your computer has similar functionality, then this may be used as a good point-of-reference.

Video Walkthrough: Enabling USB Ports in HP BIOS

What you will need:

  • Your laptop (specifically HP)
How to disable usb 3.0 in bios mode

Step One: Entering the HP BIOS

  • Begin by having your HP computer fully powered down. Now, power it up and as soon as the HP splash screen appears, press the F10 key. Typically, the F10 key is pressed 2 or 3 times to ensure that it registers. A small box with 'F10 BIOS Setup' should appear on-screen if this is done correctly.
    Note: The key pressed to access the BIOS menu may be different on your computer.

Step Two: Restoring Defaults

  • Assuming you are in the BIOS screen, you should now see a menu-style screen with multiple choices. Using the arrow keys to navigate, arrow-down to Restore Defaults and press the Enterkey. A prompt should appear, asking you to 'Load defaults,' in which you will select Yes.
  • You should automatically be taken back to the initial menu. Select 'Reset BIOS security to factory default' and again, select Yes.

Step Three: Confirming the USB Ports are On

  • Now, we will confirm that the USB ports have been turned on. Again, using the arrow keys, navigate to the right until the System Configuration panel is active. Arrow-down to Port Options and press Enter to access the menu. In this menu, confirm that all of your desired ports have a checkmark next to it.

Step Four: Testing the USB Ports

  • You may now exit the BIOS, which is done by using the Escape key. Ensure that you save changes!
  • Once the BIOS has been exited, your computer should automatically restart. Once it fully boots, plug in any USB device (preferably something like a mouse) and your computer should detect the mouse, subsequently searching for the device's drivers (if you are connected to the Internet).

Your USB ports should now be fully-functional! Again -- it is a rare case for the USB ports to somehow become disabled in the BIOS, so if this tutorial did not solve your issues then you may have issues pertaining to your drivers or there is an underlying hardware malfunction.
