Intermittent USB port on Studio 1555

I'm wondering if anyone else has reported a very annoying intermittent connection on the Right USB port of the Studio 1555.  It has been so since I first got this and I mistakenly thought it was my wireless mouse USB however, I've now found that its the internal port which appears to be wiggling.  The port is right next to the power connection and is often hit by the wire.  I'd love to know if this is a common issue and what can be done to rectify it.

Thanks for any replies.
