5329EVB, LTIB and USB Hubs,  error -71

I have two USB devices, a USB stick and a USB serial adapter.  Either seems to work okay plugged directly into the USB port of the 5329EVB.  But if I plug both in via a USB hub, I get a long series of error -71 messages. 

I've tried two different hubs, and different cabling.  I've tried the hub as both self-powered and bus-powered.

Threads elsewhere seem to point to a conflict between the EHCI driver and the OHCI driver, which doesn't apply here, yes?  They suggest removing the EHCI driver, which in my case disables USB altogether.

Boot messages attached.
