Hi stef,

I cannot give you an answer, but I assume the on board 4 port hub is 1 level. connecting one port of it to a second hub is level 2. Maybe the stack cannot support 2 levels. You could test this by disconnecting the on board hub (as if you would do a firmware update) and connecting the 7 port hub directly to the pico,

Also I am pretty sure there will be memory limitations on the total number of ports the pico stack can support.
