TI中文支持网TUSB8043是USB3.1接口的，我们处理器I.MX8是USB3.0的，想问一下能否很好的兼容？
谢谢！
Kailyn Chen：
可以的，在TUSB8044 EVM user's guide中有这样一段描述：
The USB ports can be attached through a standard USB cable to any USB 3.0 or legacy USB host, hub, or device. The TUSB8044 will automatically connect to any upstream USB 3.0 host or hub at both SS and HS. Using a legacy USB cable between the TUSB8044 EVM and a USB 3.0 host or hub forces it to HS operation。
