I kept trying, rebooted, tested, again, again, unplugged USB,
replugged... and TADA, at some point it magically worked ! 

I've typed-in a few commands, got networking (opkg update completed),
did a few more things... and ... it's now gone :(

# ping 192.168.0.202
PING 192.168.0.202 (192.168.0.202) 56(84) bytes of data.

no kernel message on desktop side : usb not unplugged...

I guess it's pretty flaky :( But still I see some (slow) progress ;)

I guess screen will be my friend.
