Ah, yes, as a quick test I can. They keyboard works fine if it's connected
to the computer instead of the hub.

The problem is probably the hub.
Also, I tested the same keyboard with another hub, the keyboard works.
Also, I tested with the original hub, but another keyboard, and it worked
too.

The problem is this hub+keyboard combination...

But, infortunatelly, changing the HUB or the keyboard isn't an option
here. I MUST make it work, even if it's an ugly solution, with this
hardware... (and it's not just because I "want to make it work"... I
really can't change...)
Isn't there a way I can tell the keyboard to "be usb 1.1" and tell the hub
"be usb 1.1" ? Will it work?

Thanks a lot for helping me!!!!
