I am design a kind of USB3 vision camera, and use NI VBAI as the testing host application. after the U3V device is clicked, the xml is transmitted to host, and necessary registers are all set correctly. if I start image acquire command, the leader packet and data packet are transmitted to host by USB3.0 bus.
the image buffer has size of 0x4000 bytes for a tranport. if I tranmit 0x4000 bytes in a packet, only the first leader packet is found in usb too busHound, no image packet is found; if I tranmit 0x4000-4 bytes in a packet continuously, the first is leader, then 0x4000-4 bytes; 1024 bytes a packet, and 14332 bytes follwed.Indeed, I continue transmitting packets in seize of 0x4000-4, why the third is divided into 2 packets;why the packet with length 0x4000 can't be transmitted successfully, the packet with length 1024 bytes is also not able to be transmitted? it is the issue from device firmware, or the requirement of USB3 vision in the VBAI?
