Purpose
This guide covers information on how to disable USB power management for USB devices.
Power Management is a function of device manager properties that allows computers to disable devices connected to the computer to save power. It is typically recommended as a standard device troubleshooting method for USB devices to disable power management.
If a sensor is idle and Windows disables the device, Apteryx XVCapture will not be able to detect the being plugged in until unplugged and plugged back in.
Disabling Power Management for USB devices
Begin by opening Device Manager (devmgmt.msc) and expanding USB controllers.
- Right-click each listed device and choose Properties.
- Navigate to the Power Management tab. If it is not shown, the device may not have the ability to toggle Power Management features on/off or the logged in user does not have permissions.
Uncheck the box for ‘Allow the computer to turn off this device to save power’
- Click OK to exit the window.
- Repeat this for each USB Hub and Controller. Other devices may show and some may not have the ability to toggle Power Management features on/off. These can be skipped.
