Hi all, I recently started compiling the 5.4. kernel starting with rc3 and noticed that both my keyboard and mouse aren't working when connected to the motherboards USB ports (they work fine when connected to an xhci extension card) and they work fine with the 5.3 series up to 5.3.6 Cheers, Benedikt Output of dmesg when unbinding/binding ehci: [ 4699.013556] ehci-pci 0000:00:1a.0: remove,
