This is what I observe: On the first connect, the musb starts with DEVCTL.Session set. On disconnect, musb_core calls try_idle. That functions removes the Session bit signalizing that the session is over (something that only in OTG is required). A new device, that is plugged, is no longer recognized. I've setup a timer and checked the DEVCTL register and I haven't seen a change in VBus and I saw the B-Device bit set. After setting the IDDIG into A mode and forcing the device to behave like a A device, I didn't see a change. Neither VBUS goes to 0b11 nor does a session start request comes. In the TI-v3.2 kernel they skip to call musb_platform_try_idle() in the OTG_STATE_A_WAIT_BCON state while not in OTG mode. Since the second port hast a standard A plug the patch changes the port to run in host mode only and skips the timer which would remove DEVCTL.Session so we can reconnect to another device later.
