It seems that you created the patch against the ti-psp release, there is another way to achieve this (one port as host and other port as device). Please refer to release/user's guide. Moreover, you should create a patch against mainline, where the musb_dsps.c is used instead of ti81xx.c, where there is no host-only or device-only mode, by default OTG mode is used. > It was fine if I configure both as device or both as host or > enable only one port, but configure both in different modes > lead to a not working configuration. > After a bit of debug I've found that probably the problem is inside > ti81xx_musb_set_mode() because this configure the controller > but does not set musb->board_mode.
