You may be right. But the wiki document UsbNet say that if I use a newer
kernel (2.6.17+), I should follow the instructions in
WindowsXpUsbNetworkHowTo, saying I should change usbf to usb0 (among
other things). But yes, maybe it is usbf I should use. (???)

But let me ask one question: do I need to set up the IP addresses for an
interface (usb0 or usbf) on the iPAQ before my Ubuntu will understand
there is an iPAQ at the end of the usb cable? That is, before the
command lsusb will say there is an iPAQ attached? I know I will not be
able to communicate between the units, but at least, shouldn't my pc be
able to see there is "something" attached, even without an IP address?

I ask because, that was the case when there was Windows on the iPAQ.

My point is, does it make sense to give the iPAQ an IP address, if my PC
are not aware of anything attached to the usb cable... ? When there were
Windows on the iPAQ I didn't had to tell Ubuntu what to look for (or
give it an IP address), it just found it. Why does Ubuntu not find the
iPAQ with Familiar on?

My guess is in the area of something with kernel-module-g-ether and
kernel-module-pxa2xx-udc. According to the wiki document
WindowsXpUsbNetworkHowTo, it should already be installed in the image
(Familiar > 0.8.3). 

"However, the new module is not the default yet because it is
incompatible with older Linux kernels (more on that below). To switch
from the old module to the new one, make the following changes to your
configuration"

and then follows the listing I mentioned earlier:

* Delete /etc/modutils/usb-eth so that the old driver doesn't get loaded
anymore 
* Create the file /etc/modutils/g_ether containing the following
contents only: g_ether
* In /etc/apm/scripts.d/usbnet and /etc/network/interfaces replace: usbf
with usb0, usb-eth with g_ether, sa1100usb_core with pxa2xx_udc 
* Reboot your iPAQ. 

I have had no luck with this...

If I look at the list of loaded modules in System Info > Modules, I see
no g_ether. Has things changed since that document was written?
