What USB ports are available on the reServer Industrial and what are their limitations?

The reServer Industrial provides 4x USB 3.1 Type-A ports (split across J3 and J4), one USB 2.0 Type-C for device mode, and one USB 2.0 Type-C for debug UART and RP2040. Each pair of USB 3.1 Type-A ports shares a current-limiting IC with a maximum total output of 2.1A — exceeding this will trigger over-current protection. All USB 3.1 Type-A ports support only Host mode (not Device mode) at 5Gbps and are hot-swappable. (Page 14-15)
