I could resolve the problem in part; for some reason (which I have to
bring up in the SHR mailing list) the interface 'usb0' in the Linux has
no IP addr: when I do in addition in Linux

# ifconfig usb0 inet 192.168.7.2/24

I can ping and ssh into the phone fine;

the question remains: what does the above error 

Apr 16 05:50:17 tinyCurrent kernel: cdce0: No valid alternate setting found
Apr 16 05:50:17 tinyCurrent kernel: device_attach: cdce0 attach returned 6

means and why device_attach returnes 6?

Thanks
