Abstract:
1. A data transmission system, comprising: a first control circuit coupled to a first device, decoding a first format data packet sent by the first device to obtain a device descriptor; a translation circuit coupled to the first control circuit, receiving the device descriptor and translating the device descriptor into a second format data packet; and a second control circuit coupled to the translation circuit, transmitting the second format data packet to a host, so that the host determines that a second device is connected, and performing an emulation flow for the first device as the second device according to the second format data packet, wherein the second device is not coupled to the first device, and the second format data packet is consistent with the second device, wherein a data transmission rate of the first device is slower than that of the second device, and the data transmission system is backward compatible to the first device.
