That is a very interesting finding. I thought the external hubs would
auto-configure to the highest version provided by the host. I would
not expect the machine to hang or crash in that particular
configuration. Do you think it is due to cheap hardware?

I should read the USB spec to try to understand what is happening, but
I am too lazy at the moment...
