Most welcome.
Be sure to keep tinkering.
Perhaps you could be of help to @kilaueabart in the thread 'Another USB2 hub problem -- sort of solved'
as he is also having some troubles. Might even come in handy for your review/troubleshooting guide.
One of the things I wonder about is the context(?) switching when you plug a 1.1 device into a 2.0 hub.
I mean, if there is a 2.0 data stream moving through the hub and then you start mousing around with a
1.1 device plugged into the same 2.0 hub, , , it all goes down the same wires, , , just sounds messy.
