Do you find your USB flash drive not recognized by the computer after plugged in for a while, but everything is functioning again when you unplug it and plug in again? If you are one of the numerous users who have had to deal with this problem, it will interest you to know that it is a problem caused by the USB Selective Suspend feature.
First of all, let's take a look at how Microsoft defines the USB flash drive selective suspend feature:
"The USB selective suspend feature allows the hub driver to suspend an individual port without affecting the operation of the other ports on the hub. Selective suspension of USB devices is especially useful in portable computers since it helps conserve battery power."
-- From Microsoft official website
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.
Many USB drive users often argue as to the importance of enabling a Selective Suspend feature. When faced with this error, you will be tempted to disable it entirely, but is it the right thing to do? Check the Pros and Cons of enabling USB drive selective suspend feature:
On a personal note, the Selective Suspend has little to offer for desktop PC users because they are always plugged into a power source when in use.
Therefore, if you are using a desktop PC, you can just turn it off to avoid the USB stick selective suspend issue in the future. However, if you are using a laptop, it is better to consider the battery consumption before turning it off.
By now, you should have made up your mind whether to disable it or not. Next, let's take a step forward and learn how to disable USB drive selective suspend setting step by step. Follow these simple steps below:
If disabling the feature doesn't help you resolve your unrecognizable USB device, consider updating your driver either manually or automatically.
To manually update your drivers go to your Device Manager or visit the website of your PC manufacturer to search for compatible drivers for your system. When you find it, install it manually.
For an automatic update, download a driver update program online and launch it. The program will scan for faulty, missing, or outdated drivers on your system then install an updated one in its place. These actions can make your USB drive recognizable again.
Hopefully, your USB flash drive is now functioning again. However, if you have tried all the solutions above but nothing happens, you need to consider the data security on your USB device.
