Greg,
Thanks for confirm my thought.
I tried with a kernel 3.16 builded by Ubuntu guys, http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16-utopic/linux-image-3.16....
And the same behaviour, the Roboot lego kit can't establishes the communication with the PC.
Do you think that with 3.18 kernel I will have a chance to resolve this ? or there aren't significantly changes related tu USB between 3.16 and 3.18 version.
I guess that the problem is on SDK library usb communication, (libusb) i'm going to make a research to this side.
There should not be any difference between USB 2 and USB 3 from your userspace program's point of view, so something is wrong in the kernel. libusb should be fine. I suggest posting the real problems you are having here on the linux-usb@vger.kernel.org mailing list and the developers there can help you out. thanks, greg k-h
