I had the misfortune to get an iPhone4 for work, so I have to deal with it too. And I ran into exactly the same symptoms as the original reporter...
Hopefully this will help: I and usbmuxd by hand to get some more debug information out of it: hawking:~# usbmuxd --verbose --verbose --foreground [20:13:11.790][3] usbmuxd v1.0.4 starting up [20:13:11.791][4] Creating socket [20:13:11.791][5] client_init [20:13:11.791][5] device_init [20:13:11.792][4] Initializing USB [20:13:11.792][5] usb_init for linux / libusb 1.0 [20:13:11.794][4] 0 devices detected [20:13:11.794][3] Initialization complete [20:13:12.010][4] New client on fd 8 [20:13:12.011][5] Client command in fd 8 len 16 ver 0 msg 3 tag 2 [20:13:12.011][5] send_pkt fd 8 tag 2 msg 1 payload_length 4 [20:13:12.011][5] Client 8 now LISTENING -- At this point usbmuxd went quiet, so I plugged in the iPhone...
