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.

Tony
