Dear Icenowy, In ae49ba1 [1] you list endpoints 1 to 4 for H3, but on the datasheet I read: Support High-Speed (HS, 480-Mbps), Full-Speed (FS, 12-Mbps) in device mode Supports bi-directional endpoint0 for Control transfer in device mode Supports up to 8 User-Configurable Endpoints for Bulk , Isochronousl and Interrupt bi-directional transfers (Endpoint1, Endpoint2, Endpoint3, Endpoint4, Endpoint5) in device mode Supports up to (4KB+64B) FIFO for EPs (Excluding EP0) in device mode Can you confirm this is correct?
