Then the only likely source is the device.  In theory it could be the
host controller, but that is very unliekely unless you use some

You can easily verify that usbnet can be ruled out by follwing the
earlier usbmon advice.

rx_submit allocates new buffers using __netdev_alloc_skb_ip_align() like
many other network drivers.
