+-Drivers need not be concerned about balancing changes to the usage
+-counter; the USB core will undo any remaining "get"s when a driver
+-is unbound from its interface. As a corollary, drivers must not call
+-any of the ``usb_autopm_*`` functions after their ``disconnect``
+-routine has returned.
++Drivers must be careful to balance their overall changes to the usage
++counter. Unbalanced "get"s will remain in effect when a driver is
++unbound from its interface, preventing the device from going into
++runtime suspend should the interface be bound to a driver again. On
++the other hand, drivers are allowed to achieve this balance by calling
++the ``usb_autopm_*`` functions even after their ``disconnect`` routine
++has returned -- say from within a work-queue routine -- provided they
++retain an active reference to the interface (via ``usb_get_intf`` and
++``usb_put_intf``).
+
+ Drivers using the async routines are responsible for their own
+ synchronization and mutual exclusion.
