Try attached EFI, basic config for pentium g4400, may work with G5400.

You need to take Shuhung's efi as an example only. I look into his efi, there are many things you may not have or need. You need to know your hardware. Adjust accordingly and take his kernel patch as reference to edit your own. It is hard work, but worth it.

Seems to be caused by BIOS settings, pls verify below BIOS setting.

1,XHCI hand-off = enable
2,Above 4G decoding = enable, or add boot arg npci=0x2000
