yeah, that hangs too, and writes nothing to the log file

the phone itself doesn't hang, and i can run any apps as normal, but
they won't download data - i tested tangogps, and it wouldn't get
tiles

so, i tried

sudo ifdown usb0
sudo ifup usb0

and everything worked fine after that, so i figure it's the networking
on the ubuntu side. any suggestions how to fix it?
