For a large part of yesterday continuing into today my USB mouse kept on disconnecting and reconnecting rendering it unusable. It seemed to work for longer depending on how it was placed in the USB drive but it still disconnected eventually. Whilst looking around online it suddenly started working again without me doing anything and has continued to do so for a good while now. However occasionally it still makes the noise as if it is disconnecting or reconnecting though it doesn't seem to change the mouse working. Any idea what has gone wrong?
