Before we start our discussion on the troubleshooting methods, first, let’s see what the causes of this are.
What are the causes of Unknown USB Device, Port Reset Failed error?
There are many causes of this error. We have listed below some of the most common causes.
- Outdated or corrupted drivers: A driver establishes a communication link between the operating system and the connected hardware. Companies release OS and software updates with time. In order to keep the hardware peripherals in a good working condition with the updated OS, drivers need to be updated. Hence, one of the most common causes of this error is outdated or corrupted drivers.
- The USB device is suspended: To save power, Windows suspends the USB device that remains inactive for a specific time. Sometimes, USB devices connected to the same USB hub become unresponsive or slow due to the Selective Suspend feature. Hence, the Selective Suspend may be one of the causes of this error.
- Hardware issues: It is also possible that the USB device showing the Port Reset Failed error has malfunctioned. You can confirm this by connecting the same device to another computer.

6] Disable C-state in your system BIOS
Each CPU has many power modes that are collectively called C-states. By default, the C-states are on. These are the power-saving states which help save energy when the CPU is left idle. The idea behind introducing C-states to computers was to cut clock signals and power from the CPU’s idle units. The C-states start with C0, which is the normal operating mode of the CPU. At C0 state, the CPU is completely turned on and is 100% active. With the increase in C number, the CPU sleeps deeper. When more signals are turned off, the CPU takes more time to return to the C0 state.
According to the users who received this error by connecting the Lenovo Thunderbolt Dock with the Lenovo laptop, disabling the C State from BIOS fixed the issue. If you have a computer of another brand, you can give this method a try. If it doesn’t work, we suggest you revert the changes in BIOS.
Do note that different brand computers may have a different process to disable the C-state in BIOS. Therefore, please check with your PC manufacturer to know the correct process to disable the C-state in BIOS.
7] Update your system BIOS
If you have tried all the above fixes but the issue still persists, we suggest you update your system BIOS.
Hope these solutions help.
