Devices that use MSD not having symink removed when disconnected

[deadprogram]

Devices like the itsybitsy-m4 are not having the symlink for their MSD mode removed when the device is disconnected. This causes the device to not be able to be flashed until the symlink is manually deleted.

Is the firmware version of itsybitsy-m4 up to date?
It can be found in INFO_UF2.TXT.
I have encountered some problems with Feather-M4 and others due to out-of-date firmware versions.
Below you will find instructions on how to Update.
