First of all, let's take a look at how Microsoft defines the USB flash drive selective suspend feature:

To make it easier for you to understand, USB drive selective suspend is a feature that only works on USB devices that are connected to a computer.
Since devices are not active round the clock, Windows will place a port that is not in use on low power and prevents data loss and driver corruption to make more power available for other tasks and a much longer period.
Flash drive selective suspend features are activated by enabling Keyboard/Mouse Wake option in the BIOS setting so to correct an error related to flash drive Selective Suspend on Windows 10 you will have to tweak a few options under this category.
