An easy solution to this problem is uninstalling the Universal serial bus controller driver. Here are the steps to follow.
Windows will install the right drivers from its driver stack that will resolve the Universal serial bus controller driver issue. Here the problematic Universal serial bus controller driver is listed under Universal serial bus controllers. The right solution for you depends on the location of the Universal serial bus controller with a yellow exclamation mark.
If the Universal serial bus controllers issue is not fixed by following steps in Solution 2, proceed to the next solution in the list. According to Windows experts, the generic hub splits one USB port into multiple ports available on your computer. The problem related to the Universal serial bus controllers might be linked to an outdated generic USB hub driver.

One of the main responsibilities of a driver for a dual-role controller is to switch between those two roles, tearing down the previous role's device node and loading the device node for the new role.
When writing the driver, use the WDF class extension-client driver model. For more information about the WDF class extension-client driver model, see Ursdevice. The class extension and the client driver represent an emulated host controller with a root hub that is capable of presenting an attached device to the system as an USB device.
The driver pair loads as the FDO in the host controller device stack. The UDE client driver communicates with Udecx by using a set of methods and event callback functions to handle device requests and notify the class extension about various events. A USB function class driver implements the functionality of a specific interface or group of interfaces on the USB device.
The class driver handle requests issued by user mode services, or it can forwards requests to USB function class extension UFX and its function client driver. If a particular interface or functionality is not provided by a system-supplied driver, you might need write a function class driver. Alternatively, you may implement it as a user-mode service.
For example, the MTP class driver runs as a user-mode service that transferring files to and from the device. The USB function client driver is responsible for implementing a function controller-specific operations. The client driver is also responsible for handling power management, and PnP events. Write a USB function controller client driver. Write a filter driver that supports detection of chargers, if the function controller uses the in-box Synopsys and ChipIdea drivers.
The client driver handles hardware operations and events, power management, and PnP events. If you are developing an xHCI host controller that is not compliant with the specification or developing a custom non-xHCI hardware such as a virtual host controller , you can write a host controller driver that communicates with the UCX class extension.
