So, after putting ->disconnect stuff to workqueue, what's your suggestion to sync udc with gadget driver? When the vbus is off (disconnection), usually, the udc will put the controller to low power mode to save power, if the udc put the controller to low power mode and close the related code, the defer ->disconnect will hang the system. > Sebastian > > -- > To unsubscribe from this list: send the line "unsubscribe linux-usb" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
