[SOLVED] Thunar (XFCE4) Does not Auto-mount USB Drive

Question

After reading some posts related to USB auto-mounting in Thunar and yet still having the problem, I decided to post this. Thunar used to detect the USB drives and auto-mount them. These days (I GUESS after moving to systemd), It cannot do so. Still, there is the icon of USB drive on the left side panel, but when I click on it to browse it, I get this error:
Failed to mount "USB_LABLE".
Error when getting information for file
'/media/usbhd-sdc1': Transport endpoint is not connected.
I am still able to use "sudo mount..." and get the job done, but I would prefer the convenient way it used to work. Here are some information about my system:
command> cat ~/.xinitrc
if [ -d /etc/X11/xinit/xinitrc.d ]; then
for f in /etc/X11/xinit/xinitrc.d/*; do
[ -x "$f" ] && . "$f"
done
unset f
fi
exec startxfce4
command> loginctl show-session $XDG_SESSION_ID

I'd rather not edit the /etc/fstab; the way Thunar used to behave, was working with every new USB. I wonder if anybody can shed some lights.

Answer 1

The error looks suspiciously like one I had not so long ago and it turned out I still had an 11-media-by-label-auto-mount.rule in /etc/udev/rules.d.  Once I removed that and rebooted everything was fine again.
