[SOLVED] MSI B550M PRO-VDH - USB wake-up events - do these work ?

[lejeczek]

Hi guys.
I've recently changed my mobo and cannot get USB keyboard to wake up my Linux - all my previous hardware did not have this issue.
I've fiddled with BIOS settings but to no avail - does USB wake up your (Linux) system on this mainboard?
many thanks, L.

I'd check to see if your BIOS is pending an update. Following that, have you made sure your wake events option is enabled;

? Wake up event by OS option enabled? Disregard the OS part.

Hi L.,

This issue is pretty common after a motherboard change, especially if the new board handles USB differently or has stricter power-saving modes. Here's a checklist to help you troubleshoot and hopefully get USB keyboard wake working on your Linux system tellpopeyes

Findings: when set to BIOS controlling wakup, USB wake must be enabled - even if keyboard & mouse wakeups are enabled - which kind of make sense but is not 100% clear - to me - for who, nowadays, uses keyboard/mouse different than USB(ps/2). I was thinking - obviously keyboard/mouse enabled would include USB keyboard/mouse, setting USB to enabled, would meany any/all/other than keyboard/mouse, USB devices. It all works now.
thanks.
