I found this fix in -mm:   gregkh-usb-usb-rmmod-pl2303-after-28.patch
> It did *not* fix the problem.
That should fix the memory leak after getting that error and let you
unload the module, right?
Nope.  No difference here.

If I plug the 1.1 hub/dock into another external hub, no problems.
I recommend doing that :)
It's not like you get _any_ speed differences by using a USB 2.0 hub
with this device...
I suppose not!  ;)

But the USB2.0 "hub" is built-into my notebook,
and the "cascading hubs" solution is likely to stop
working when we begin enforcing per-port power limits
on these devices.

I'm rebuilding to try the suggested patch now.

Cheers
