It hardly ever does for me. 360revolution also has a great built in USB explorer. I usually use a plain old 360 usb explorer outside of modio though.
You need to make sure your USB Device has been configured. If you haven't do the following: Go to System Settings. Go to Memory Units. Select your USB Device and then configure it to your desire. If that's not the problem, then do these next steps: On your PC, go to the USB Device Folder. Now click "Tools" on the Tool Strip. Click "Folder and Search Options". Then click on the "View" tab. Under "Hidden Files and Folders", select "Show hidden files, folders and drives". Click "OK". An Xbox 360 Folder should appear, you can now try and open it in Modio. If it doesn't work in Modio, you can download USBxTAF Explorer and alternatively use that.
