Bug#782442: USB3 external HDD not recognized [regression]

I tested that branch (HEAD commit 190f6b0b), and the issue is still the
same. Directly after booting, if I plug in the disk, it doesn't work
(with the "root hub lost power" error). Removing the cable, setting
power/control to "on" for all PCI devices, then plugging it back in, the
disk works fine.

The package says "Seagate Expansion 5TB". But I'm not sure these are all
using the same controller; for example, I also have a "Seagate Expansion
3TB" that works fine.
(I'm removing Wang, Yu <yu.y.wang@intel.com> from the recipients, as I
keep getting bounces from that address.)
Kind regards,
