A watchdog interface checks if the hardware is still responsive. The ep driver 
uses the old interface, which still works, but is replaced with a new 
interface. The driver should be updated, yet it has not happened and as such 
the driver may stop working in a future major release. I do not know the 
current status of if_watchdog and when it's scheduled to be removed.
