I would guess it's a PCIe-based USB 3.1 controller (ASMedia ASM3142?)
and some USB chips permanently wired to it on the same board, you could
investigate with 'lspci' and 'lsusb -t' (when everything is working).

Is this a complete log? And the device was really working during those
six minutes before "setup address" failure? Usually, address setup
happens once immediately after device connection, not sure what would
lead to it being repeated later.
