* Input Parameters:
* class - The USB host class entry previously obtained from a call to create().
* configdesc - A pointer to a uint8_t buffer container the configuration descripor.
* desclen - The length in bytes of the configuration descriptor.

* Returned Values:
* On success, zero (OK) is returned. On a failure, a negated errno value is
* returned indicating the nature of the failure
