Hub device and control system

A control system comprising:

• a host device;
• a peripheral device;
• and
• a hub device responsible for communication between the host device and the peripheral device and comprising:
• an upstream-facing port coupled to the host device;
• a downstream-facing port coupled to the peripheral device;
• a memory;
• and
• a control chip coupled to the upstream-facing port, the downstream-facing port, and the memory and comprising:
• a first transceiver interface coupled to the upstream-facing port;
• a second transceiver interface coupled to the downstream-facing port;
• a first processing circuit coupled to the first and second transceiver interfaces so that the host device communicates with the peripheral device;
• and
• a second processing circuit coupled between the first processing circuit and the memory,
• wherein:
• in response to the first processing circuit receiving an access command from the host device via the first transceiver interface, the first processing circuit triggers the second processing circuit to access the memory.
