If you are facing a problem with a USB connection or when you plug in a USB and get the message “USB device not recognized,” you are at the right place. In this post, we will discuss how to fix this issue and how to stop your laptop or tablet battery from draining. Recently, many users have reported facing these issues, and in most cases, the problem is caused by Windows: USB Selective Suspend. If, like others, you too are wondering what this feature is? And can you disable it? Keep reading. We will answer these questions and will explain how to disable it so that you avoid facing USB connection-related issues.
What is a USB Selective Suspend
It is a built-in feature in Windows that allows the hub driver to suspend an individual port without affecting other connected USB ports. The service comes in handy for laptop users as it helps save battery.
USB devices like printers, scanners, headphones, etc, are not always active but still consume power. Therefore, to prevent unnecessary power consumption, Windows uses this feature to put unused USB devices into a low-power state automatically. That said, when the USB is suspended, the external devices are put into an idle state so that charging power can be saved, and you don’t need to charge the laptop frequently. However, this feature works when the USB is connected and your system has the recent USB drivers running. (If you want to know whether or not your PC has the latest USB drivers, try Advanced Driver Updater.)
What is the Use of this Feature
When you connect a device via USB and the port is active, the data transfer schedule for that port is active, and the system’s physical memory is used, which means there is power consumption, and the CPU cannot go into sleep or hibernate. Therefore, the unused USB ports should be suspended to let Windows hibernate or go to sleep.
For those who work on a laptop or tablet, this feature is a boon as they can save battery without affecting the working of other connected devices. However, the feature can sometimes trigger problems, like random disconnection of USB ports, unrecognized USB devices, and others. Hence, disabling selective USB suspension settings is suggested when you face such issues.
