Mass storage doesn't work over USB

Hi,
I've got at weird problem. My hackintosh refuses to recognise mass storage USB-devices. Mouse, keyboard and external audio card works fine, but it refuses to mount storage devices. Every once in a while I can get a flashdrive to mount, but never a HDD/SSD.

I've tried disabling XHCI in UEFI. Also I'm using the InjectAllUSB kext.

Help?

I'm on Mojave btw (version 10.14.5 (18F132) )
