When I boot up my computer the USB "remove hardware" icon loads in the tray, even though there isn't a devise plug in the USB port. I'm usually able to get rid of the USB icon by going thru the procedure as if there was something plugged in. I believe this started months ago when I was having problems with a MP3 player. The USB port still works fine, as I use it for my camera and memory stick all the time. Any ideas on how to remedy this problem? Thanks for your help.
