* Name: usbhost_findclass
|

*
|
||||
* Description:
|
||||
* Find a USB host class implementation previously registered by
|
||||
* usbhost_registerclass(). On success, an instance of struct
|
||||
* usbhost_registry_s will be returned. That instance will contain all of
|
||||
* the information that will be needed to obtain and bind a struct
|
||||
* usbhost_class_s instance for the device.
|
||||
*
|
||||
* Input Parameters:
|
||||
* id - Identifies the USB device class that has connect to the USB host.
|
||||
*
|
||||
* Returned Values:
|
||||
* On success this function will return a non-NULL instance of struct
|
||||
* usbhost_registry_s. NULL will be returned on failure. This function
|
||||
* can only fail if (1) id is NULL, or (2) no USB host class is registered
|
||||
* that matches the device class ID.

* Name: usbhost_registerclass
|

*
|

* Description:
|
||||
* Register a USB host class implementation. The caller provides an
|
||||
* instance of struct usbhost_registry_s that contains all of the
|
||||
* information that will be needed later to (1) associate the USB host
|
||||
* class implementation with a connected USB device, and (2) to obtain and
|
||||
* bind a struct usbhost_class_s instance for the device.
|
||||
*
|
||||
* Input Parameters:
|
||||
* class - An write-able instance of struct usbhost_registry_s that will be
|
||||
* maintained in a registry.
|
||||
*
|
||||
* Returned Values:
|
||||
* On success, this function will return zero (OK). Otherwise, a negated
|
||||
* errno value is returned.
