Aspects of the disclosure relate to a protocol for communication of information. The protocol can be a non-standard universal serial bus (USB) protocol and can guarantee bandwidth and latency for information communication between a USB host and a single USB device. In one aspect, the non-standard USB protocol can employ a repeating message sequence that is fixed, or static, and preconfigured, the sequence comprising alternating transmission of messages between a first device (e.g., a host device) and a second device (e.g., a peripheral device). |

1. A method comprising:
transmitting, by a first device via a serial communication link, a first message to a second device, the first message having a first fixed length; receiving, at the first device via the serial communication link, a second message from the second device in response to transmitting the first message, the second message having the first fixed length; transmitting, by the first device via the serial communication link, a third message to the second device in response to receiving the second message, the third message having a second fixed length; receiving, at the first device via the serial communication link, a fourth message from the second device in response to transmitting the third message, the fourth message having the second fixed length; and performing, by the first device, a repeating cycle of transmitting an additional first message, receiving an additional second message in response to the additional first message, transmitting an additional third message in response to the additional second message, and receiving an additional fourth message in response to the additional third message wherein the repeating cycle is performed for communication between the first device and the second device thereby fulfilling a bandwidth requirement between the first device and the second device based on the first fixed length and the second fixed length. |
