I was wondering if it is possible to turn off power delivery to peripherals after PC is turned off?
I have a mic and keyboard which both have LED elements and they are quite annoying at night when sleeping.
Only solution so far was either turning off power supply switch or removing USB cables, but I wonder if there is a "more professional" solution, probably settings in BIOS or windows that could be used in this case?
I have B450 Aorus Elite V2 mobo, Ryzen 7 1700 CPU and Windows 10 in my system.
Peripherals: Genesis Thor 150 RGB keyboard and AT-2020 USB microphone.

Funny, but after 15 minutes of more in-depth digging I found a solution, hope it helps others in need.
In BIOS under Power Management there is this option "ErP", by turning it on system stops delivering power to peripherals while pc is shutdown.
