Hi Daniel and all,

An linuxmao.org user gave answers to these questions today. Here you go:

maxime at Ubuntu-MAO:~$ lsusb -t

I'll be asking him to try connecting a mouse to one of the hub port and to get a dmesg from there.

Hope that can help in any way. If you would need some more information, please let me know.
