Hi Caesar,

Are you saying that just msleep(25) in that function like this solves
your issue?

diff --git a/drivers/usb/dwc2/core.c b/drivers/usb/dwc2/core.c
index 39a0fa8..e8a9688 100644

                         __func__, hsotg->dr_mode);
                break;
        }
+
+       msleep(25);
 }
 


Although that is still not ideal, it's better than the alternative.
