This issue does not affect the functioning of the USB device, and users generally do not notice the issue. However, when you run the PowerCfg.exe tool and use the /energy option, a message that resembles the following is displayed:
This device intermittently entered the USB Selective Suspend state during the trace. Processor power management may be prevented when this USB device is not in the Selective Suspend state. Note that this issue will not prevent the system from sleeping.

This issue occurs when the following conditions are true:

This issue does not affect the performance of the USB device, nor does it prevent your computer from sleeping or hibernating.
