* Name: usbhost_enumerate
*
* Description:
* Enumerate the connected device. As part of this enumeration process,
* the driver will (1) get the device's configuration descriptor, (2)
* extract the class ID info from the configuration descriptor, (3) call
* usbhost_findclass() to find the class that supports this device, (4)
* call the create() method on the struct usbhost_registry_s interface
* to get a class instance, and finally (5) call the configdesc() method
* of the struct usbhost_class_s interface. After that, the class is in
* charge of the sequence of operations.
*
* Input Parameters:
* drvr - The USB host driver instance obtained as a parameter from the call to
* the class create() method.
* funcaddr - The USB address of the function containing the endpoint that EP0
* controls
* class - If the class driver for the device is successful located
* and bound to the driver, the allocated class instance is returned into
* this caller-provided memory location.
*
* Returned Values:
* On success, zero (OK) is returned. On a failure, a negated errno value is
* returned indicating the nature of the failure
*
* Assumptions:
* - Only a single class bound to a single device is supported.
* - Called from a single thread so no mutual exclusion is required.
* - Never called from an interrupt handler.
