Well I've got usbmon compiled into the kernel and wireshark running but it
didn't give me a whole lot more to go on than what you had found. It's been
a long time since I've had to decode USB traffic so I'll have to dust off
the cobwebs. I do see the GET DESCRIPTOR request coming from the host
Thanks Jon but that wasn't the easy answer I was looking for! Everything
seems fine on the hardware side but obviously I've missed something. Off to
the linux-usb list...

Try posting to the linux-usb list. That's where the experts are.

You are failing in hub_port_init() in usb/core.c. But something is
really broken. That is not a normal failure mode. Error -32 is
-EPIPE. That's the error you get when a USB transaction fails.
You can use Wireshark to sniff the USB ports.

Still working on my USB Hub design and am getting the following errors when
a USB device is plugged into the hub. If nothing is plugged into the hub
when it enumerates I'm not seeing any errors.
