I finally found time to do a bisect and I found:

USB: EHCI: make ehci-pci a separate driver

This patch (as1625) splits the PCI portion of ehci-hcd out into its
own separate driver module, called ehci-pci. Consistently with the
current practice, the decision whether to build this module is not
user-configurable. If EHCI and PCI are enabled then the module will
be built, always.

As the problem start.

I do have EHCI and PCI enabled so it should be working. Any clue about
why it breaks it?
