SOURCE: Cant connect LG Renoir via USB, connection problem

I get this all the time and it is really annoying.
What I do to solve it for me is to is to tern all my mobile application off and then reconnect the USB cable.

To close all open applications: press the white hard key (in the middle of the red and green), and you customisable menu appears. At the top of the screen is a grey tab with a dark grey triangle (like a play button), press this and you see all (if any phone application are open), press the end all button on the screen. Then to confirm action pres yes to stop all tasks.

Hope it solves you problem.

You probably have the USB selection set incorrectly on the phone. Go to Menu, then Connectivity, then USB, then select "Data Service". The should fix it.

You need to change the usb connection type on the LG. By default it is set to "mass storage", if you change it in your "connection" setting to "data storage" when you next plug in your phone, it will have all of the PC Suite settings available without any grayed out non-functionality.

Hey - I'm in the same boat, did you get it working? I connect and get the USB menu up, but the tv says that the file is corrupt, even though the iPod works fine when it's not connected to the tv.
