After upgrading to Ubuntu 8.10 my Sony Ericsson phone while it's in file transfer mode. Unlike the other thread I saw about this model, mine will not show up at all. performing the dmesg | tail -30 command got me this:

I have several usb devices fed through a hub at the moment, but it will not work when it's the only usb device connected.
Interestingly, Ibex recognizes the modem function while in phone mode.
