My Steel Legend x570 was resuming from suspend/sleep via my wireless USB keyboard flawlessly until I upgraded to BIOS v2.1. Is this a known issue? Is it working for everyone else?

Same problem here, seems something broken in the BIOS as I haven't been able to fix or find the USB power setting anymore.

Same here, I had to disable PS2 keyboard wake to get back the USB power settings, but even with it on it still won't wake from sleep. I have to press the power button on the PC to wake.
I read it may be erp function, is it possible to disable it from the BIOS? |

I think I have narrowed down the problem. Even with "USB Power Delivery in Soft Off State (S5)" enabled in the BIOS, the USB ports lose power when the machine goes to sleep. I have a USB hub with a power LED that goes off whenever it sleeps. I rolled back to 1.9 and had the same problem.
