usb_reset_device — warn interface drivers and perform a USB port reset
|struct usb_device * udev|
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).
The caller must own the device lock. For example, it's 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
If an interface is currently being probed or disconnected, we assume its driver knows how to handle resets. For all other interfaces, if the driver doesn't have pre_reset and post_reset methods then we attempt to unbind it and rebind afterward.
