Removing d_WMDM.dll and d_USBMass* from the Plugins folder where MediaMonkey is installed should allow for this. They may return when you update (so repeat the process then).

I'm wondering, and hoping there might a way to prevent or perhaps disable entirely MediaMonkey's [i][b]Portable Device Sync[/b][/i] feature without having to disable a device manually in the options section? I'm not using it all and finding it intervenes with other USB devices I may insert and then trying to eject. Thank you. Just a thought though.
