I don't know if gspca uses ISO endpoint to transfer stream data. If it uses bulk to transfer video data, it will share the usb bandwidth with other devices. thanks, -- Ming Lei -- 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
