* Quirk to work around issue generated by the SN65LVPE502CP USB3.0 re-driver
* that causes ports behind that hardware to enter compliance mode sometimes.
* The quirk creates a timer that polls every 2 seconds the link state of
* each host controller's port and recovers it by issuing a Warm reset
* if Compliance mode is detected, otherwise the port will become "dead" (no
* device connections or disconnections will be detected anymore). Becasue no
* status event is generated when entering compliance mode (per xhci spec),
* this quirk is needed on systems that have the failing hardware installed.
