critical communications services have failed to start

[reglyj]

I have tried a lot of roms, but I still got this error message when synchronized with pc.
I'm sure the firewall is closed.
And I have try to change the usb connection mode to "serial", it didn't work.

about 1 or 2 minutes after I connected miniusb to xv6700, I got a "cannot obtein a ip address" error from the xv6700.I tried to set the ip address by myself, but still "critical communications services have failed to start"

Thanks.
