I had similar hunch first, but did not worked. I have tested this patch and did not helped. To be precise this is what I have tried: - boot w/o cable connected - boot w/ board connected to PC (device mode) - boot w/ OTG-A cable with USB keyboard - boot w/ OTG-A cable connected to powered USB hub and the same keyboard w/ and w/o this patch I have the same flood of prints in all cases.
the config I have for linux-next: https://pastebin.com/KixvyiRR
Fwiw I have checked where the is_active is set - which causes the prints: musb_core.c:musb_start() if (musb->port_mode != MUSB_PORT_MODE_HOST && musb->xceiv->otg->state != OTG_STATE_A_WAIT_BCON && (devctl & MUSB_DEVCTL_VBUS) == MUSB_DEVCTL_VBUS) { musb->is_active = 1; } else { devctl |= MUSB_DEVCTL_SESSION; } this was the only place where the is_active was set to 1.Regards, Tony 8< ----------------------- diff --git a/drivers/usb/musb/omap2430.c b/drivers/usb/musb/omap2430.c --- a/drivers/usb/musb/omap2430.c +++ b/drivers/usb/musb/omap2430.c @@ -91,12 +91,6 @@ static void omap2430_musb_set_vbus(struct musb *musb, int is_on) } otg_set_vbus(otg, 1); - } else { - musb->is_active = 1; - otg->default_a = 1; - musb->xceiv->otg->state = OTG_STATE_A_WAIT_VRISE; - devctl |= MUSB_DEVCTL_SESSION; - MUSB_HST_MODE(musb); } } else { musb->is_active = 0;- Péter -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
