* usb ports working only with pci=noacpi (bugzilla 94261)

Here all details (dmesg, lspci etc):
https://bugzilla.kernel.org/show_bug.cgi?id=94261

The machine is:
LENOVO 90BX0018IX/Aptio CRB, BIOS O07KT49AUS 12/18/2014

OS is a Debian Wheezy amd64.

The issue is that USB ports work only starting the kernel with 
"pci=noacpi" parameter.
Without it, nothing plugged into usb ports is detected.
In particular, "lsusb" returns "unable to initialize libusb: -99".
The same happens with a 3.13.11 kernel (same config).

I've tried newer kernels (3.18.8, 3.19) and they show the same issue. With 
the difference that, with "pci=noacpi" they don't start at all.
