The ArmSoM Sige5 has several USB ports: a Type-A USB 3 port (USB2 lines going through a hub), a Type-A USB 2.0 port (also going through a hub), a Type-C DC input port that has absolutely no USB data connection and a Type-C port with USB3.2 Gen1x1 that's also the maskrom programming port. Enable these ports, and set the device role to be host for the host ports. The data capable Type-C USB port uses a fusb302 for data role switching.
