When I plug in the phone into the computer and answer the prompt on the phone to give permission for the computer to read the information on the phone, the files window opens, but it is constantly loading, with no files or folders every showing up.
An lsusb at the command line generates this output:

Edit: I just discovered that if you wait long enough (maybe an hour?) the files and folders finally show up. Surely this must indicate some abnormality in connection? Also when navigating into a folder on the phone to see the contents it seems the long wait begins again.
