Simply charging by USB does not count as an active USB connection.
You can charge without unmounting the device.

With some creative software you could also remove the need to have
only one side using the MMC card. Doing that would probably require
exporting the card vs NFS instead of as a USB block device. Plugging
in the USB cable could automatically trigger loading/unloading the USB
networking module and start the in-kernel NFS server.

Another way would be to add a simple UI that pops up when an active
USB host is connected. It would just ask if you wanted the MMC
exported over USB and give you a chance to say no.
