Hi @Excel
Tinker board 2 supports 3x USB 3.2 Gen 1 TYPE-A ports and 1x USB3.2 Gen 1 TYPE-C OTG port. The TYPE-A and TYPE-C ports are each in a separate USB 3.2 Gen 1 group.
Since the three TYPE-A ports of Tinker Board 2 are implemented by USB HUB. When each TYPE-A port is used individually, each port can support up to 5Gbps; however, when all 3 TYPE-A ports are used simultaneously, they will share 5Gbps of bandwidth.
If you have a requirement for two 5Gbps USB ports, it is recommended that you use TYPE-A and TYPE-C to implement your requirement, respectively.
Thanks.
