USB Host Controller Issues on New Windows 10 PC

I am migrating from a Dell Inspiron (Haswell) laptop to an Asus UX501VW. Both are running Windows Version 10.0.10586 with the same software set. But I am experiencing new problems with installing Safe-Net Sentinel USB Drivers on my new PC which comes with the latest hardware.

On the Asus notebook, the windows USB troubleshooter says that the «USB controller is in a failed state or is not installed». I don’t get any error messages on my earlier Dell computer.

The Device Manager, however, shows that all of the USB drivers are «working properly» and that all of the latest driver versions are installed. Under the USB Controller branch in the Device Manager there is: 1) Intel USB 3.0 eXtensible Host Controller 1 (Microsoft), 2) USB Composite Device and 3) USB Root Hub (xHCI)

I have filed a support request with Asus Technical Support, but the drivers that are having the problem are part of the Windows operating system. Can you provide some suggestions?

We regret for the inconvenience. Let me assist you to resolve the issue.

To be able to assist you better, let us know a few more details on the below questions.

• What do you mean when you say ‘I am migrating from a Dell Inspiron (Haswell) laptop to an Asus UX501VW’?
• Which Windows troubleshooter did you mean when you say ‘USB troubleshooter’?
• Did you check if you are using a Power saving option from the available Windows power schemes? If so, change it to high performance scheme.

As an initial recommendation, I suggest you to follow the below steps and check if it helps to resolve the issue.

1. Press Windows Key + R and type devmgmt.msc in the Run dialog box to open Device Manager.

2. In the Device Manager window, expand Universal Serial Bus controllers and look for your USB device, do a right click over it, select Properties.

3. In the property sheet, switch to Power Management tab and uncheck the option Allow the computer to turn off this device to save power. Click OK and exit.

If it still does not help, I suggest you to check for the Device Status of all the individual devices under USB controller and check if any of the devices is in the state The drivers for this device are not installed along with a Device Status code.

Device Manager displays the following message in the Device Properties dialog box, on the General tab, in the Device Status text box.

Now, follow the below method and check if it helps to resolve the issue.

Method 1

Disconnect all other peripheral devices connected to the PC and check if the issue still persists.

Next, run the Hardware and Device Troubleshooter

Follow these steps to run the Windows in built troubleshooter. Although not a USB troubleshooter in particular, but helps to identify any potential driver related issues present in your PC.

a) Write Troubleshooting in the search box and hit enter.

b) Click on Troubleshooting tab.

c) Click on view all option on the upper left corner.

d) Select the Hardware and Device option from the list.

e) Click Next to run the Hardware and Device Troubleshooter.

Method 2

Next, check if updating the USB drivers present in your PC helps to resolve the issue. Follow the below steps.

• First of all, Press Windows logo + R from keyboard. It will open RUN.
• Now type devmgmt.msc and press Enter to open Device Manager.
• You will see all the driver list of your PC. Expand USB Host Controller

Double click on your USB driver in Device Manager. Then Click on Driver tab and select Update.

Also, check for the latest available drivers directly from the manufacturer’s website.

Method 3

Windows has in built Driver Verifier as well to identify problematic drivers. The Driver Verifier Manager, tests each specified driver at startup. If it detects a problem, it identifies it and then stops it from running. Here’s how:

1. Type verifier in Windows Start menu Search box and hit Enter.

2. Navigate to Create Standard Settings > Click Next > Automatically select unsigned drivers > Next.

3. At last you have two options Cancel or Finish.

• If you click on Cancel, no changes are made to your system configuration.

From the list which is presented, you can manually try to Roll back, Update, Disable or Uninstall the Driver.

• If you click on Finish, then restart the system, you may be presented with an error message.

This will include the name of the buggy driver along with an error code.

4. Now reboot the system in to update, disable or uninstall the particular driver.

5. Type verifier/reset in Windows Start Menu Search and hit Enter to disable the Driver Verifier Manager.

Write to us with the updated status and the required information related to USB driver issues for us to be able to assist you further.

Thanks for responding to my note. Some clarifications that you requested:

• I am upgrading computers for better hardware. I am looking to keep the same software in my new computer, the Asus UX501VW. The older computer (which had no issues) had USB 2.0 and USB 3.0 ports. The new computer only has USB 3.0 ports and a USB type C port that supports thunderbolt 3.0. Both my new computer and old computer are using the same USB Host controller. Both computers are using the latest Windows build as referenced in my earlier note.
• The USB Troubleshooter is the Windows USB troubleshooter that was downloaded from the Microsoft website. https://support.microsoft.com/en-us/help/17614/automatically-diagnose-and-fix-windows-usb-problems . When I run this on my new laptop, I get a scary message: “USB host controller is in a failed state or is not installed”. I believe that this is the cause of my problems. My old computer shows no issues when I run the same troubleshooter.
• As suggested, I have switched the computer power mode to higher performance and unchecked the power saving option. In the driver property settings. Method 1 shows no change to the status of the computer.

I went through each of the suggestions that you listed below in Method 2 and 3. Here are my updates:

The attempts to update the drivers under the Device Manager resulted in no change. It states that the latest drivers are currently installed. (No improvement from Method 2)

The driver verifier says that all of the existing drivers are signed. There are no unsigned drivers present.

I also ran the check for “drivers built for earlier versions of Windows”. It found none, so it appears that all of the drivers are built for the current windows version. (No improvement from Method 3)

Asus Tech Support:

I have contacted Asus Technical support and submitted a support request. They have not gotten back to me yet. Asus also provides a software update utility in the Asus bloatware package. I have run this and there are no updates. After discovering my problem, I did some research on the Windows Community board and found previous recommendations to un-install the Asus AiCharger driver under Device Manager / USB. I did that but it did not fix the issue.

It may be hard for Asus to respond to this because the USB drivers are from Microsoft and the Windows USB troubleshooter is also from Microsoft.

Please let me know if you have other suggestions. I really appreciate your support!
