What Causes the Error 0x800701b1?

Before you get into the details on how to fix 0x800701b1, it is essential to know the suspected culprits which may be causing the error. This can help you detect what exactly causes it. Some of the culprits include:

1. Corrupted Windows System Files

Windows operating system constantly tries to update itself with new features and security patches. Sometimes, the files used for these updates can corrupt and cause this error code 0x800701b1.

2. Malware or Virus

When this error code is encountered, it means that Windows has blocked the application or file you are trying to access for some reason.

It could be a virus, malware infection, or another security issue. You should run a full computer scan with an up-to-date anti-virus program to fix this problem.

3. Inconsistent / Incompatible driver

Inconsistent or incompatible drivers can cause a variety of issues on your computer. Drivers are pieces of software that allow the operating system to communicate with hardware components such as printers, sound cards, and video cards.

When an incompatible driver is installed, it can cause problems with the hardware or other software on the computer. This can lead to errors, crashes, and even data loss.

To prevent these issues from occurring, it’s important to make sure that all of your drivers are up-to-date and compatible with your system.

You should also check for any known incompatibilities between the driver and the hardware or software you use. If you find any incompatibilities, uninstall the driver and replace it with a compatible version.

4. USB 2.0 port is insufficient

USB 2.0 ports are insufficient to provide power for certain devices, such as external hard drives. The ports only provide 4.0V of output power. This power can be insufficient.

Additionally, USB 2.0 devices may not work with USB 3.0 ports due to incorrect configurations or outdated drivers on the computer.

To fix this issue, users can try several methods, such as using Device Manager to scan for hardware changes, restarting the computer, disabling and re-enabling the USB controller, or using a regular USB 2.0 port instead of a 3.0 port.

If these methods do not work, users may need to get a new display and attempt to use a different USB port for the item they are trying to utilize or reinstall the Universal Serial Bus (USB) controllers in Device Manager to resolve the issue of “Not Enough USB Controller Resources” error on Windows 10 computers.

5. Insufficient PSU Output

Insufficient PSU output means your computer’s power supply unit (PSU) is not providing enough power to support all the connected devices.

This can be caused by having too many devices connected to your computer or an inadequate PSU for your needs.

It’s important to note that faulty USB ports can also cause this error, incompatible or inconsistent drivers, bad Windows updates, and files or folder ownership changes to which you don’t have access.
