AB350 M pro 4 can't detect nvme!

I am really struggling to get my mother board working, there's no way the nvme (mp500 240 gb corsair) gets read by the system, also windows doesn't show me the drive.
I tried to look in the bios and using the method explained in the forum, but it doesn't work.
I have updated the bios to the 4.5...Also, the pc wakes up with key pressure, even if i disabled this function in the bios and the usb ports are always on even when i shut down the pc.
I can't really get out of this situation and it's beginning to be frustrating. Please help me.

Cpu: Ryzen 1300 x
Ram: ballistix 1x8 gb -2400

Do you have another drive in the SATA3 port on the motherboard?

Toffus, what does not work to show the NVMe drive in UEFI/BIOS?  Here is an screenshot of mine.

All my SSDs are in a RAID, so you cannot see the individual drives here, but this should direct you to where to look.  Please post a more complete list of your specifications, including your power supply and Windows version and UEFI/BIOS version.  I suspect the USBs are using 5 Volt standby and there may be a way to disable this but why?  Please look in your Device Manager and see if you have any yellow ! Enjoy, John.

EDIT:  vazma, please open a new thread.

Toffus, can you post the same screenshot as I have.  Navigate to the BIOS/UEFI page and push F12 with a FAT formatted USB stick plugged.  Thanks and enjoy, John.

Thanks, Toffus.  At this point you need to talk to ASRock and/or test your SSD in another system or a known working SSD in your system.  Good lock and enjoy, John.
