[pkg-fso-maint] works, don't know why Re: No USB connection to NEO with Debian

Dear Luca, dear Joachim,
to start with the end: I cannot reproduce what I have originally reported for the moment.
My latest symptom is a long delay for the ssh login prompt that seems invariant of the
modules already added and does not go away with subsequent attempts. I cannot recall to
have observed this afternoon when I first reported that is works. Maybe the delay with the
login also disappears soon again. I apologize for the apparent noise.
Some more details on what I tried I have summarised below. I'll summarise my experiences
in a few days again.

I was unclear in my original report. The ifconfig line was executed on the host machine,
the one that is directly connected to the internet. And maybe worse, I have not seen it
for a while. Maybe because I had tried it with the OpenMoko kernel first (to change
seetings in the mounted Debian SD). I'll investigate.

My first report referred to the host machine, my later report about ifconfig -a referred
to the neo.

I executed the install.sh script, chrooted into Debian's root, then installed the openmoko
kernel via apt-get.
That Debian kernel version is 2.6.24-20081103 from Dec 17 2008.

Explained above: first host, second neo.

I have googled them in the meantime. And am surprised. In one of my last sessions I had
installed ping on the neo (which might also be nice to be installed via the install.sh
script ?) and found that I can ping the host. And (no idea why) the converse from host to
neo also worked. Still, ssh just stalled, while it was immediately up on the other system.
And just by sheer frustration, I tried sshing from the neo to the host, and it worked
immediately. But from the host to the neo, it only go up to
ssh neo -v

this point. Then I started writing this reply, while I was busy writing this email, all of
a sudden, ssh continued. And with some more reboots down the line, I can confirm, it still
works with none of the modules added.
