Comments
A SET_INTERFACE request appears on the bus.
All pipe handles associated with the interface will be unbound and all
pending requests will be cancelled. If this request returns with success,
new pipe objects are available. The operation
IOCTL_USBIO_GET_CONFIGURATION_INFO (
) may be
used to query all available pipes and interfaces.
