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
The datasheet may be copy-n-paste error (such kind of errors appear
frequently in Allwinner documents).
The endpoint configuration is from the BSP source code [4].

Can you confirm this is correct?
Thanks,
Nuno
