Strangely the user manual of this board shows

USB Keyboard/Mouse Power On
Allow the system to be waked up by an USB Keyboard/Mouse device.

Under ACPI config.
But there's no such option under the BIOS I have.]]> Mon, 21 Apr 2025 15:33:13 +0000 https://forum.asrock.com/forum_posts.asp?TID=106949&PID=191606&title=b550m-pro4-wake-by-usbpound#191606 https://forum.asrock.com/forum_posts.asp?TID=106949&PID=191511&title=b550m-pro4-wake-by-usbpound#191511 Author: user81

Hi,
I have Asrock B550M Pro4 motherboard with BIOS P2.30. AMD Ryzen 5 3500X CPU
Everything is working fine.

However I was just wondering if it's possible to Wake this system from USB?
I have a USB to Rj45 adapter that can wake this system from Sleep(S2) but not from S3 shutdown.
Of course I can always wake this from S3 by sending magic packet to onboard Ethernet.
But if it's possible via USB, do let me know.
I am not too sure exactly what setting come into effect in BIOS.
Thanks and regards.]]> Sat, 19 Apr 2025 23:40:18 +0000 https://forum.asrock.com/forum_posts.asp?TID=106949&PID=191511&title=b550m-pro4-wake-by-usbpound#191511
