Are you tired of your USB devices disconnecting randomly or failing to function properly? You’re not alone. Many users have experienced this frustrating issue, and it’s often caused by the USB selective suspend feature. In this article, we’ll delve into the world of USB selective suspend, explore its purpose, and provide a step-by-step guide on how to disable it.
Understanding USB Selective Suspend
USB selective suspend is a power-saving feature introduced in Windows Vista. Its primary purpose is to conserve energy by suspending the power supply to idle USB devices. This feature is designed to reduce power consumption, especially in laptops and mobile devices. However, it can sometimes cause issues with certain devices, leading to disconnections, data loss, or malfunctioning.
How USB Selective Suspend Works
When a USB device is idle for a specified period, the operating system sends a suspend command to the device, which then enters a low-power state. This state reduces the device’s power consumption, but it can also cause problems if the device is not designed to handle the suspend command properly.
Common Issues Caused by USB Selective Suspend
Some common issues caused by USB selective suspend include:
- Random disconnections of USB devices
- Failure to recognize or detect USB devices
- Data loss or corruption during file transfers
- Malfunctioning or erratic behavior of USB devices

What is USB Selective Suspend Command?
The USB Selective Suspend Command is a power management feature in Windows that allows the operating system to suspend power to specific USB devices when they are not in use. This feature is designed to conserve power and prolong battery life in laptops and other mobile devices. However, it can sometimes cause problems with certain USB devices, such as printers, scanners, and external hard drives.
When the USB Selective Suspend Command is enabled, Windows will periodically check the USB devices connected to the system and suspend power to any devices that are not currently in use. This can cause problems if a device is not properly recognized by the system or if it requires a constant power supply to function correctly. In some cases, disabling the USB Selective Suspend Command may be necessary to resolve issues with USB devices.
Why would I want to disable the USB Selective Suspend Command?
You may want to disable the USB Selective Suspend Command if you are experiencing problems with a specific USB device. For example, if you have a printer that is not printing correctly or an external hard drive that is not being recognized by the system, disabling the USB Selective Suspend Command may resolve the issue. Additionally, if you have a device that requires a constant power supply to function correctly, disabling this feature may be necessary to ensure proper operation.
Disabling the USB Selective Suspend Command can also be useful if you are using a device that is not designed to be suspended, such as a USB audio interface or a USB MIDI device. In these cases, disabling the feature can help to ensure that the device functions correctly and does not experience any interruptions or dropouts.
How do I disable the USB Selective Suspend Command in Windows?
To disable the USB Selective Suspend Command in Windows, you will need to access the Device Manager and locate the USB Root Hub device. From there, you can disable the “Selective suspend” option in the device’s properties. Alternatively, you can also disable the feature through the Windows Registry Editor or by using a third-party utility.
It’s worth noting that disabling the USB Selective Suspend Command may have some negative effects on power consumption, particularly in laptops and other mobile devices. Therefore, it’s recommended to only disable the feature if you are experiencing problems with a specific USB device and to re-enable it when the problem is resolved.
Will disabling the USB Selective Suspend Command affect my system’s performance?
Disabling the USB Selective Suspend Command should not have a significant impact on your system’s performance. However, it may cause your system to consume more power, particularly if you are using a laptop or other mobile device. This is because the feature is designed to conserve power by suspending power to USB devices when they are not in use.
In terms of system performance, disabling the USB Selective Suspend Command should not cause any noticeable slowdowns or other issues. However, if you are using a device that requires a constant power supply to function correctly, disabling the feature may be necessary to ensure proper operation.
Can I disable the USB Selective Suspend Command for a specific device only?
Yes, it is possible to disable the USB Selective Suspend Command for a specific device only. To do this, you will need to access the Device Manager and locate the device in question. From there, you can disable the “Selective suspend” option in the device’s properties. This will prevent Windows from suspending power to the device, while still allowing the feature to function for other devices.
It’s worth noting that disabling the USB Selective Suspend Command for a specific device may require some technical knowledge and expertise. If you are not comfortable accessing the Device Manager and modifying device properties, you may want to seek the help of a qualified IT professional.
