Note: It applies to Windows 7 as well.

Use Device Manager to scan for hardware changes

Use Device Manager to scan for hardware changes. After your computer scans for hardware changes, it might recognize the USB device that is connected to the USB port so that you can use the device.

To scan for hardware changes, follow these steps:

1. Click Start, and type devmgmt.msc in the Start Search box and hit enter.
2. Device Manager opens.
3. In Device Manager, click your computer so that it is highlighted.
4. Click Action, and then click Scan for hardware changes.
5. Check the USB device to see whether it is working.

Uninstall and reinstall USB drivers.

You may check after uninstalling and reinstalling the USB drivers if you are able to connect. You may disconnect all USB devices and then perform the following steps:

a. Click Start, and then click Control Panel.

b. Click System and Maintenance, click System, and then click Device Manager.

Note: If Control Panel is in Classic View, double-click System, and then click Device Manager.

If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.

c. In Device Manager, double click to expand «Universal Serial Bus controllers«, right click on the Host Controller, click «Uninstall» and click «OK«.
Check if at all there is an exclamation mark along the driver, it suggests issues with the driver installed.

d. Repeat the step 2 to uninstall all items under «Universal Serial Bus controllers».

Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.

Note: Connect the USB devices to the Computer only after the conflict drivers are uninstalled and once the Computer is restarted.

If you still face the same issue then you may check for the updated USB device drivers using windows update.

I have exactly the same problem.

Initially I thought it was skype related as it always occurred during skype video calls.

As I went to all procedures described in the thread (manufacturers site to update drivers). I even upgraded my BIOS.
I also performed a sfc/scannow for corrupt system files from elevated command prompt.

All was working from last wednesday until yesterday.

I now suspect the problem is related to the inbuilt webcam. The drivers are from microsoft and from. 2006 and the system reports it as updated and the latest release.

Today, as I barely touched «scan for hardware changes» I immediately got the BSOD and the VIDEO DXGKRNL FATAL ERROR.

I honestly have reached my limit, knowledge wise and was not expecting to buy a new computer.
I have a Dell Inspiron 16GB ram Intel i7

Windows 10 does not automatically scan for hardware changes when I plug in any USB device.

When first installing Win 10, I had no issues regarding automatically detecting USB devices being plugged in. All of the sudden when trying to play a game with a wired Xbox 360 controller or plugging in a USB thumb drive, the lights flash for a split second and then go dark. No sound from windows indicating a device being plugged in and it doesn’t show up on device manager. It still detects immediately when a USB device has been removed. As soon as I manually click «scan for hardware changes» it works just fine. If I unplug and plug it back in afterward, then I have to manually scan again.

Note: all of my device drivers seem to be up to date, and the devices work as expected after manually scanning.

Is there a service or something that needs to be started in order detect these hardware changes automatically? Maybe a registry key I need to add or modify?

Any help will be greatly appreciated!

Windows 8 freezes when running «Scan for hardware changes» in Device Manager, requiring forced shutdown

I’ve just installed Windows 8 Pro on a system that ran Windows 7 w/o issue. After completing a clean Windows 8 Pro setup, I went trough installing drivers, but found that the installer package for my sound card drivers caused Windows 8 Pro to lock up and become completely unresponsive. I had to force a shutdown by pressing the power button for 4 seconds.

In troubleshooting the issue, I found that manually installing the drivers via device manager caused no problems. Also, installing the drivers available through Windows Update also worked w/o issue. However both of these methods fail to install parts of the driver that the drive package include. I then went to uninstall the device the driver package again. I uninstalled the Sound Card via Device Manager and selected «Delete the driver software for this device.» When I followed this with a «Scan for Hardware Changes» to re-list my sound card, I found that Windows 8 hung again.

After trying other possible solutions with no resolution, I tried re-installing Windows 8 fresh. To rule out a possible problem with Windows 8, I opened Device manager as soon as I was able after Windows setup and ran «Scan for hardware changes». Again Windows 8 freezes. I cannot place fault on any post setup software or driver. This appears to be an issue with Windows 8 itself.

One final note, occasionally «Scan for hardware changes» will actually work, but most often it causes the system to hang.

Is anyone else having this issue? Can anyone provide assistance? (specs below for comparison)
