How do I fix a USB device driver problem?

A driver problem occurs on a Windows computer when the device driver malfunctions or gets corrupted. When a device driver malfunctions, the device could not be able to communicate with the operating system. In most cases, the driver problem can be fixed either by updating the device driver or reinstalling it.

Should I disable USB Selective Suspend setting?

As described earlier in this article, the Selective Suspend setting allows Windows to suspend the USB device that is inactive for a specific time by reducing the power supply to the USB port to which that device is connected. It does not affect the other USB ports.

Generally, it is not recommended because after disabling this setting, all the USB ports start consuming an equal amount of power which results in fast battery drain. But sometimes, the Selective Suspend setting causes some errors. In such a case, you can disable it.
