Hi I am having a problem to with the MTP device. Bottom right corner of my screen has the window that says found new hardware...MTP device. I can not close out the window because it keeps coming back. Then I hear this like bubble sound when it's on the screen. Any suggestions? I think its for my new phone that I downloaded on the laptop. I am going to uninstall it and reinstall it and see what happens. Any other suggestions please let me know thanks...

Here is the solution:

MTP: Media Transfer Protocol (MTP) is a protocol with an accompanying set of drivers developed by Microsoft to connect portable devices to a Windows XP PC and synchronize digital media content between those devices and the PC. MTP is geared toward portable devices with hard drives. With regards to your issue, what do you mean by all of your memory of your device is empty? Does all the songs are all deleted?
