What is causing the iusb3xhc.sys BSOD crashes?
We investigated this particular issue by looking at various user reports and the repair strategies that are commonly being used to fix this particular error message. As it turns out, there are multiple causes that could lead to a BSOD of this kind. Here’s a shortlist of potential culprits that can cause constant iusb3xhc.sys blue screens:
Method 1: Reinstalling the USB Host Controller Drivers
In most cases, this particular issue is caused by an improper or corrupted Host USB Controller driver. Several users that we’re also encountering this issue have reported that the issue was resolved after they reinstalled all USB Host controller drivers. It’s possible that one or more USB controllers have become tainted by file corruption. In this case, you should be able to resolve the issue by using Device Manager to remove or reinstall the USB Host controller responsible for the critical crash. Here’s a quick guide on uninstalling & reinstalling the USB controllers using Device Manager: If the same issue is still occurring, move down to the next method below.
Method 2: Installing the Intel Chipset drivers (if applicable)
As it turns out, this particular issue can also occur in instances where you’re using a motherboard that is designed to work with Intel chipset driver. If you’re using Windows 10, you’re OS should automatically install the required chipset drivers. But on older Windows versions (or if your Windows copy is not activated), chances are you’ll need to do it manually in order to resolve the iusb3xhc.sys related BSODs. Here’s a quick guide on installing the required Intel Chipset drivers automatically using the Intel Driver & Support Assistant (Intel DSA): If you’re still encountering BSOD crashes related to the iusb3xhc.sys file, move down to the next method below.
Method 3: Running SFC and DISM checks
As it turns out, unexpected BSODs related to iusb3xhc.sys can also occur due to an underlying system file corruption instance. It’s possible that a driver or other element that works in relation with iusb3xhc.sys has become corrupted and is crashing the operating system whenever this scenario repeats. Several users that were also affected by this issue have reported that they managed to resolve the issue by using a couple of built-in utilities. After doing so successfully, a large portion of them reported that the critical crashes have stopped occurring. SFC (System File Checker) and DISM (Deployment Image Servicing and Management) are two built-in Windows utilities capable of fixing system file corruption. The only difference is they do it in different ways. Since DISM is mostly used in instances where SFC is not capable of resolving the issue by itself, we highly encourage you to perform both scans in order to resolve any possible system file corruption that might end up causing the issue. Here’s a step by step guide on running SFC and DISM scans from an elevated Command prompt: If you’re still encountering BSOD crashes related to iusb3xhc.sys, move down to the next method below.
Method 4: Uninstalling 3rd party security suite (if applicable)
As several users have reported, crashes of this kind can also be triggered by a 3rd party security suite or firewall. Kaspersky is commonly linked with BSOD crashes related to the iusb3xhc.sys. If this scenario is applicable and you’re indeed using a 3rd party AV suite, chances are you’ll be able to stop the crashes by uninstalling the 3rd party security suite and ensuring that you leave no remnant files behind. Several affected users struggling with the same issue have reported that the BSOD crashes have suddenly stopped after they uninstalled their 3rd party AV suite and moved over to the built-in solution (Windows Defender). Here’s a quick guide on installing the 3rd party security suite: If the same issue is still occurring, move down to the next method below.
Method 5: Clearing the CMOS
If the problem is caused by a memory issue, resetting the CMOS (Complementary metal-oxide-semiconductor) might allow you to resolve the iusb3xhc.sys related crashes. But keep in mind that this procedure might reset some custom BIOS settings to the default values. So if you have previously overclocked the frequencies of your controller, the changes will be lost after you take out the CMOS battery. Here’s a quick guide on clearing the CMOS battery: Note: The instructions below are only applicable if you’re encountering the issue on a desktop computer.
