 The option ''nosuid'' is missing for usb0...usb3, which prevents the normal user to unmount it.
+I've uninstalled ''usbmount'' without any obvious problems so far.
+According to (([[https://community.linuxmint.com/software/view/usbmount]])) ''pmount'' is used instead, which is installed on my Linux Mint 19.1 handles the automatic mounting of USB drives, which results e.g. to such a line in the output of ''mount'':
+  /dev/sdc on /media/karl/E2A3-F90D type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)

-Flash drives should not be mounted with the mount-option ''sync'', since this could cause such issues.
