I checked what you said with kernel 2.6.26 rc9. I set num_ports to 5. It
worked quite well until I tried to connect to a non-existing endpoint.

However, the problem is that the Yakumo Delta needs to connect to the 2nd
endpoint. You can connect to the first one but you don't get any data.

Is there any good way to tell the ipaq driver to use the 2nd endpoint? Maybe
one could provide a different struct usb_serial_driver ipaq_device depending
on the usb id or an option which tells the driver to use 2 endpoints.
