The ICE40 Host controller driver (ice40-hcd) is registered as a SPI protocol driver and interacts with the SPI subsystem on one side and interacts with the USB core on the other side. It supports only 1 Full-Speed port. The bridge chip does not maintain any port states. Root hub port logic is simulated in the software. Control and Bulk transfers are supported.
