Parameters
- endpoint
- 
            Type: guint8The address of a valid endpoint to communicate with. 
- data
- 
            Type: An array of guint8A suitably-sized data buffer for either input or output. The length of the array is specified in the lengthargument.The data is owned by the caller of the method. 
- length
- 
            Type: gsizeThe length field for the setup packet. 
- actual_length
- 
            Type: gsize*The actual number of bytes sent, or NULL.The argument will be set by the function. The argument can be NULL.
- timeout
- 
            Type: guintTimeout (in milliseconds) that this function should wait — use 0 for unlimited.
