How to resolve USB device failures on Razer Blade 15 (Early 2021) under heavy load?

I have a Razer Blade 15 (Early 2021) – RZ09-0369 laptop that exhibits USB device failures when I use it for gaming or other intensive tasks. The failures affect my USB headphones, mic, and keyboard, causing audio distortion, input lag, and mic feedback. The only way to restore normal functionality is to reboot the laptop. This problem started about a month and a half ago, without any apparent hardware changes. I have tried the following troubleshooting steps, but none of them worked:

• Updating GPU drivers
• Checking and updating power settings on USB devices in device manager
• Ensuring no overheating
• Contacting Razer Support

The

problem seems to be USB-specific, as my wireless mouse (also USB) does not experience any issues, and my FPS in-game remains stable. I am looking for any possible solutions or suggestions to fix this issue. Thank you.

Possible causes of the issue

There are several possible causes of the USB device failures on your Razer Blade 15 laptop. Some of them are:

• A faulty or corrupted USB device or cable. Sometimes, the USB device or cable may be damaged or defective, causing intermittent or permanent connection issues. This may affect the performance and functionality of the device, as well as the other devices connected to the same port or hub.
• A faulty or outdated USB driver. The USB driver is the software that allows your laptop to communicate with the USB devices. If the driver is faulty or outdated, it may cause compatibility or stability issues, resulting in device failures or errors. This may also affect the power management and performance of the USB devices and ports.
• A faulty or outdated motherboard driver or firmware. The motherboard is the main circuit board of your laptop, which controls the communication and power supply of all the components, including the USB ports. If the motherboard driver or firmware is faulty or outdated, it may cause issues with the USB devices and ports, such as power surges, overcurrent, or undercurrent. This may damage the devices or cause them to malfunction.
• A Windows update or configuration issue. Sometimes, a Windows update or configuration may change some settings or files that affect the USB devices and ports. This may cause conflicts or errors, resulting in device failures or unrecognized devices. This may also affect the power management and performance of the USB devices and ports.
