near perfect opencore build--could use some help/suggestions

the build is...

mobo: b450m ds3h cpu: ryzen 3 2200g gpu: rx 570 efi: https://gofile.io/d/DnT4Ln

damn near everything is working great besides wake/sleep and some usb problems. it will go to sleep fine but it usually takes smacking the space bar a couple/few times before it decides to wake up. and when it does wake up, usb devices are unmounted--but usb mouse and keyboard seem to be fine? could it be bios settings possibly? any help would be greatly appreciated.

thanks!
