That's not surprising, because usb-storage doesn't know anything about what's happening on the mass-storage device it connects to. All it does is send the commands that it gets from the SCSI subsystem to the device and receive the results back. It has no idea whether there is a mounted filesystem on the device, if the filesystem contains any files, or whether a scanning operation is running, A better place to look for fixing this might be the filesystem code. That's where the information about mounting, files, and scanning can be found. Alan Stern
