The Enable Slot command timed out when a USB device gets plugged: [ 212.156326] xhci_hcd 0000:03:00.3: Error while assigning device slot ID [ 212.156340] xhci_hcd 0000:03:00.3: Max number of devices this xHCI host supports is 64. [ 212.156348] usb usb2-port3: couldn't allocate usb_device AMD suggests that a delay before xHC suspends can fix the issue. I can confirm it fixes the issue, so use the suspend delay quirk for Raven Ridge's xHC.
