Hi,
I have Buffalo BBR-4MG router, and it use ADM5120P SoC.
I made the patch for AHCI driver *today*.  :-)
This works on my BBR-4MG, so please try it.

Please note: This patch may not correct logically. Just quick-hacks.

(After insert an USB device, the controller receives a port reset from
upper USB sublayer. This cause disabling the ports. So, re-enabling it
before controls.)

And, A Happy New Year! :-)
