Parameters
Deactivated endpoints will have a STALLED status. If all endpoints are stalled, it will disconnect
the USB interface from the Host.
Stalls portions of the USB interface: The Endpoints to be stalled are configurable.
Void USB_Stall ( IN char cUSBEndpointStall );
cUSBEndpointStall: Input parameter
Specifies which endpoints are to be stalled by this function. The other endpoints
remain in their previous state. This parameter can be the result of an OR operation
between the following values if several endpoints are to be disabled:
Unstalls portions of the USB interface: The Endpoints to be unstalled are configurable.
Void USB_UnStall ( IN char cUSBEndpointUnStall );
cUSBEndpointUnStall: Input parameter
Specifies which endpoints are to be unstalled by this function. The other endpoints
remain in their previous state. This parameter can be the result of an OR operation
between the following values if several endpoints are to be disabled:
Send data to the Host through Endpoint 1 (BULK IN). When the buffer size is bigger
than the Maximum Packet Size (specified by the Descriptor string initialized in the
USB_Init()

} USB_t;
USBData: Input parameter
Specifies the pointer to the data to be transmitted to the Host.
USBLen: Input/Output parameter
On input, specifies the number of bytes to send to the Host. On output, specifies the
current number of bytes sent to the Host.
