Tunneling USB2 data using USB4-based configurations

A Universal Serial Bus (USB) device for processing tunneled USB2 data, the device comprising:

• a Universal Serial Bus (USB) Type-C connector;
• and
• a first routing circuit communicatively coupled to the USB Type-C connector, the first routing circuit configured to:
• decode USB2 data received from a USB2 device;
• packetize the USB2 data received from the USB2 device together with timing information into a plurality of USB4 tunneled packets;
• and
• encode the plurality of USB4 tunneled packets for transmission to a second routing circuit via an upstream tunneled path between the first routing circuit and a USB controller of a USB4 host system based on the timing information, the upstream tunneled path including the USB Type-C connector, the transmission being dynamically adjusted based on a size of the USB2 data.

A method for tunneling USB2 data, the method comprising:

• configuring by a first routing circuit of a Universal Serial Bus 4 (USB4) host system, a downstream tunneled path between a USB controller of the USB4 host system and a second routing circuit;
• packetizing outgoing USB2 data received from the USB controller together with timing information into a first plurality of USB4 tunneled packets;
• and
• encoding the first plurality of USB4 tunneled packets for transmission to the second routing circuit via the downstream tunneled path based on the timing information, to initiate processing of the outgoing USB2 data by a USB2 device associated with the second routing circuit, the transmission being dynamically adjusted based on a size of the outgoing USB2 data.
