 /************************************************************************************
+ * Name: sam_getdevinfo
+ *
+ * Description:
+ *   Get information about the connected device.
+ *
+ * Input Parameters:
+ *   drvr - The USB host driver instance obtained as a parameter from the call to
+ *      the class create() method.
+ *   devinfo - A pointer to memory provided by the caller in which to return the
+ *      device information.
+ *
+ * Returned Values:
+ *   On success, zero (OK) is returned. On a failure, a negated errno value is
+ *   returned indicating the nature of the failure
+ *
+ * Assumptions:
+ *   This function will *not* be called from an interrupt handler.
