So I am back with more tests on this problem.
Intel itself told us it is a problem on the driver for the XHCI host
controller. I will put some stuff here now what I goo from Intel:
Let me explain why I came back to you with this problem.
We have already tried the same thing with an echo device

Does my log means it has nothing to do with kernel itself ?
Maybe you're experiencing a problem with link power management. Some
changes were just merged into Greg KH's development tree (the usb-linus
branch), and they should appear in the next 3.14-rc release. You could

Hello Peter,
one short remark
Application-specific or vendor-specific are often frowned upon in
other contexts but if the protocol is documented publically then it
is a great way to take advantage of all that USB offers, and it is
explicitly supported by the specification. Use bDeviceClass
Hello Peter,
many many thanks for your long and detailed answer.
On the protocol design:
First, using CDC-ACM means sacrificing all structured communication
offered by the USB packet bus and settling for such primitive use of
USB is not a decision that should be made lightly. Almost all
