Yes, use CURRENT :-)

That is the way it should be done. I have a PCI card here with a hub
included to make 4 out of 2 ports :-)

Pitty it does not list the interface descriptor. It might have given
some more information on the class/subclass/protocol in use.

(hub/serial/parallel)

Looks like they glued the hub, serial and parallel simply together.

Sorta very much unlike the mac. It's one device with 2 interfaces
(compared to 3 devices: a hub, a keyboard and a mouse :)

HID keyboard

HID mouse

The HID keyboard/mouse is supported under 3.2 supposedly. There are
people using it on a daily basis, with some limitations as in not
disconnecting the things.

thanks a lot!
