Zusammenfassung:Some aspects of the disclosure provide various techniques for tunneling a Universal Serial Bus (USB) packet using cut-through techniques in a USB4 system. The disclosed cut-through techniques can avoid the use of store-and-forward (SAF) operations to tunnel a USB3 packet (e.g., USB 3.2 packet) through a USB4 link so that the latency of the tunneled USB3 packet can be reduced. Furthermore, the disclosed cut-through techniques can reduce the need for a large data buffer in a USB controller/adapter when SAF operations are used to tunnel USB3 packets.
