usba_hcdi_pipe_reset() entry point is designed to take a pipe in an arbitrary state and return it to the same state it was in after a call to usba_hcdi_pipe_open(9E). While this entry point does some similar things to the usba_hcdi_pipe_stop_intr_polling(9E) and usba_hcdi_pipe_stop_isoc_polling(9E) entry points, there are some notable differences.
This entry point is synchronous. The host controller driver should take the following steps on the pipe before returning:
This entry point is called by the broader USBA framework as part of closing a pipe or in response to a device stall.
usba_hcdi_pipe_reset() function should return USB_SUCCESS. Otherwise, it should return the appropriate USB error. If uncertain, use USB_FAILURE.
