Desire to know the way to fix the not enough USB controller resources message on Windows 10? Must read this in order to find out why it occurs and what you can perform to fix it in a simple way. In this guide you will learn about the way to Fix the Error on Windows: “Not Enough USB Controller Resources”

Here I want to explain why this message appears in the first place, and how it is able to impact the performance of your peripherals. After, I will take you the steps required to fix it.

Fortunately, the solution is very easy. It is better to understand why it often occurs in the first place additionally the solution doesn’t really make much sense.

Why Do I Keep Getting The “Not Enough USB Controller Resources” Message?

You probably notice the USB controller resources message popping up rarely as you use your computer. Probably it occurs when you plug something in, or probably. When you use a program that uses hardware in some way. For instance, an audio or webcam recording software.

Occasionally, the text will appear and it will look like there has been no functional change to your hardware. But other times it is also able to cause problems – your USB devices probably. Only stop working altogether, or they probably not perform as deliberate.

EndPoints

However, the purpose of this sounds complex, but it is basically quite straightforward. It is to do with something known as the EndPoints. Similarly, each USB controller has a limited number of EndPoints visible. It is sort of like how many lanes of traffic can be occupied at the time. Hence the different devices will need a various number of EndPoints.

For instance probably something small such as a Bluetooth USB dongle will require just 3 EndPoints. While something such as a USB DAC probably uses 10, or even more.

So the problem often happens when your EndPoints are capped. A USB 3.0 controller has a limited number of EndPoints, just 96 on Intel and older AMD based systems. So whether you contain many USB devices plugged into your USB 3.0 ports. You are going to run into this problem.

The USB controller is the chip used to communicate/connect data between your USB ports and your computer. Depending on your motherboard, you probably have one or further USB 3.0 controllers.

Furthermore, on top of this, each USB 3.0 port itself contains a restriction of just 16 EndPoints. So just this means that whether you have a USB hub plugged into a USB 3.0 port. You probably run into some problems on that port itself, which could cause some problems.

Fixing the Error “Not Enough USB Controller Resources”

If you want to fix this issue, then you have to perform the first thing that is to is ensure. That you are not using more EndPoints than are available. Simply there are three basic ways to perform this. First, you are able to move some of your current USB devices to USB 2.0 ports.

USB 3.0 is faster, so you should leave USB 3.0 for devices that transfer data at high speeds. Then move your peripherals – your keyboard and mouse – to USB 2.0. Both mouse and keyboard use very little data to work. So then you will find no advantage in plugging those into USB 3.0 ports.

However, on top of this, take high-powered peripherals like your microphone, headset, and audio DAC to USB 2.0. While you probably have listened to the rumors that DACs and audio equipment benefit from USB 3.0. Hence there is no truth to this. USB 2.0 has twice as many EndPoints as USB 3.0, so whilst USB 3.0 is faster, there is more room for devices that require more power to run on USB 2.0.

Secondly, whether you are utilizing a USB hub, confirm to plug it into USB 2.0, too. Whether you still click an EndPoint cap. Receive the same message saying that you don’t have enough USB controller resources, unplug some of your devices from your hub and plug them in elsewhere.

Thirdly, Whether you manage many USB devices and cannot find a solution to your current system. So then you could also consider upgrading to AM4. All AM4 based systems have a total of 254 endpoints per USB 3.0 controller, a massive improvement over current Intel and older AMD architecture.

Precis

Eventually receiving this message means you have to run and rearrange the devices plugged into your USB ports. Generally just switching the most power-hungry devices from USB 3.0 to USB 2.0 will fix that.
