Many users encounter this specific Hardware ID in their system logs when it starts behaving erratically (e.g., constantly waking a laptop from sleep or spiking CPU usage with "interrupts").

If you are seeing this ID in your logs or Device Manager and suspect it is causing issues, follow these steps to force proper power management:

1. Identify the Problem in Device Manager:

2. The Fix: Disable "Allow Wake": If this device is waking your computer from sleep unexpectedly:

3. The Registry Fix (The "Selective Suspend" Trick): If the device is causing high CPU usage or lag, it is likely failing to enter a low-power state. You can force Windows to manage its power more aggressively via the Registry:

This forces the hub to power down its ports when not in use, saving battery life and stopping CPU interrupt storms.
