Whenever I successfully connect my LG VX9200 to my PC, just after few seconds it suddenly disappears. Then the message pops up that device is removed even though I hadn’t. The after few seconds it will again get connected. What is this all happening? Why is my LG VX9200 often getting disconnected for few seconds from my PC when I had already connected it successfully? How can I fix this problem? By the way I am using Mac. Please help. Thanks.
