Title:
MacBook Pro USB 3.0 Devices Unrecognized

Status in linux package in Ubuntu:
Incomplete

Bug description:
If my MacBook Pro boots with a USB 3.0/3.2 device (e.g., thumb drive)
connected, then those devices are recognized. But if the thumb drive
is not connected when the computer boots then the Linux kernel doesn't
see it or access it. This holds true whether the thumb drive is
directly connected to a USB-C port or via a USB 3.0 USB hub. If the
thumb drive is connected to a non-USB 3.0 port on the USB hub, then it
is seen and recognized and operates correctly (albeit more slowly).
