"Power off device with the console" with Series X

[phero]

Hi,

I currently use the Titan Two in the following setup:
- A via USB to DualSense
- B via USB to Xbox One controller
- Output via USB to Series X

It works great and I'm happy with the device. However, the "Power off device with the console" has an issue. When I power off the console, the Titan Two successfully turns off as well. However, when I check the next day, the Titan Two is powered on again, even though the Series X is still off.

Not sure what is causing this. Perhaps the Series X pings the USB devices occasionally, even when standby? I use the "Energy-saving" power mode on the Series X (not "Instant-on").
