usb_reset_composite_(9)
NAME
usb_reset_composite_device - warn interface drivers and perform a USB
port reset
SYNOPSIS
int usb_reset_composite_device(struct usb_device * udev,
struct usb_interface * iface);
ARGUMENTS
- udev
- device to reset (not in SUSPENDED or NOTATTACHED state)
- iface
- interface bound to the driver making the request (optional)
DESCRIPTION
Warns all drivers bound to registered interfaces (using their pre_reset
method), performs the port reset, and then lets the drivers know that
the reset is over (using their post_reset method).
Return value is the same as for usb_reset_device.
The caller must own the device lock. For example, itīs safe to use this from a driver probe routine after downloading new firmware. For calls that might not occur during probe, drivers should lock the device using usb_lock_device_for_reset.
