Also, in terms of throughput this change has the same effect to interrupt endpoint as 290ba200815f "Bluetooth: Improve USB driver throughput by increasing the frame size" had for the bulk endpoint, so users of the advertisement bearer (e.g. BT Mesh) may benefit from this change.

I upload two traces from usbmon module. One from a kernel without the fault commit. So it is working fine. And another from a kernel with the fault commit. It fails when is plugged.
