[SOLVED]USB Mounts & Unmounts on it's own

Hey it's great to be here and using Ubuntu Karmic - I'm new at this but have been using it for about 6 weeks now and enjoy it a lot as well as the forums. Haven't had to post anything really I've found the solutions by searching the main forums or the great how-to's on the web if I had a problem.

I have one now I can't sort out though - I've noticed that my USB connections keeps mounting and unmounting for no apparent reason and I can't figure it out. This gets pretty frustrating since my keyboard and mouse are also wireless. Any help will be greatly appreciated.

This happens randomly not when I plug in or unplug the USB device.

Seems to have sorted itself out

Glad to see it was resolved.

How do i mark this as solved? I cannot find the button i used before? Thanks in advance for the help

Of course its not a button it was in the thread tools drop down buts its no longer there??
