why it occurs and how to fix it

iusb3xhc.sys is a problematic item that is indicated among the information on the blue screen of death (BSoD) with the code 0x0000007e. This BSoD can manifest itself on any version of Windows, from Windows XP to the latest builds of Windows 10.

Causes of BSoD iusb3xhc.sys

There are several reasons for BSoD iusb3xhc.sys. The most common is corrupted or incompatible USB host controller drivers. Fortunately, this problem can be easily solved through the device manager.

In rare cases, problems with drivers for USB host controllers can occur due to the antivirus software installed on the user’s system. Some users on the network claim that their antivirus decided to quarantine the host controller driver itself or a file that was important for its correct operation.

Another common reason is the lack of a driver for the Intel chipset in the system. Of course, this problem only occurs in systems based on an Intel processor. A simple driver installation will put everything in its place.

The next reason is trivial damage to certain Windows system files. As silly as it may sound, such a scenario can arise literally at any moment in time. And BSoD is an obvious sign that something is wrong with the system. Fortunately, the user has the means to restore system files.

And the last one is problems with cached data related to RAM on your system. In this case, the solution is to disconnect the CMOS battery from the motherboard.

BSoD solution methods iusb3xhc.sys


Method # 1 Reinstalling the USB Host Controller Driver

Incorrectly working drivers often cause various problems. BSoD iusb3xhc.sys can occur due to improper USB host controller drivers. To reinstall these drivers, do the following:

  1. right-click on Start and click on the item “Device Manager”;
  2. open the section “USB controllers” in the device manager;
  3. click on each RMB item and select “Remove device”;
  4. do this for each USB controller and restart your computer.

Method # 2 Installing Intel Chipset Driver

It turns out that BSoD iusb3xhc.sys can occur on systems where the driver for the Intel chipset is not installed. Typically, this driver is automatically installed on the system; however, this may not happen on older versions of Windows or copies of Windows that have not been activated. Go to this link, download the Intel specific driver installation application and follow the instructions.

Method # 3 Running SFC and DISM

Let’s assume that some of the system files in your copy of Windows have been corrupted. In this case, you need to resort to the SFC and DISM utilities. They will automatically check system files and try to fix the damage found. Here’s how to use these utilities:

  1. right-click on Start and click on “Command Prompt (administrator)”;
  2. write the command “sfc / scannow” and press Enter;
  3. after the SFC is finished, restart the computer;
  4. open the command line again and run the command “DISM / Online / Cleanup-Image / RestoreHealth” in it;
  5. restart your PC after running DISM.

BSoD iusb3xhc.sys should be gone if it was corrupted Windows system files.

Method # 4 Removing third-party antivirus

Unfortunately, some antivirus software can interfere with the normal operation of the system. Perhaps the most common culprit behind the emergence of iusb3xhc.sys is Kaspersky antivirus. We recommend that you try uninstalling your third-party antivirus and see if that fixes the situation. You can uninstall the antivirus through the Applications and Features component in the system settings.

Method # 5 Reset CMOS

If BSoD is caused by memory problems, then you can try resetting your CMOS. Some users claim that they managed to eliminate iusb3xhc.sys by removing the CMOS battery from the motherboard. We turn off the computer, open the system unit / open the laptop case, carefully remove the CMOS battery from the motherboard and insert it back after ten seconds.

We hope you managed to get rid of iusb3xhc.sys on your computer.
