No X Server after configuration

[foobuntu]

Preamble:
Xubuntu 18.04 LTS

Issue:
I followed the installation from the README.md up to where it says put

Section "InputClass"
    Identifier "Tablet"
    Driver "wacom"
    MatchDevicePath "/dev/input/event*"
    MatchUSBID "<VID>:<PID>"
EndSection

in /etc/X11/xorg.conf.d/50-tablet.conf.
First "problem" there was no xorg.conf.d directory. Is that correct?
I created the directory and then the 50-tablet.conf inside the directory, with the appropriate VID:PID of course, restarted the machine and there is no xserver anymore, just a black command line I can log-in to. I then remove the created xorg.conf.d directory, restarted the machine and the xserver is running again.
What am I missing? What can I do to get it working correctly?

X now uses udev to setup, adding xorg.conf.d files overrides this. causing your nonexistent defaults to be used... Is my guess.

here are mine as an example.

So, I created the 50-tablet.conf in /etc/udev/rules.d/, I restarted my machine. This time I have xserver running properly but when I do xsetwacom list like it's said in the README.md to check if my device is handled by the Wacom driver, I get nothing. No output, no error, just nothing. So, I'm still kind of lost with this.
The tablet and pen is working though, I just can't configure it...and the tablet is also recognized as a usb storage. It's a Huion 1060Plus 8192, btw.

@foobuntu, could you please attach your 50-tablet.conf and X.org log to a comment?

[foobuntu]

Sure.
This is my entire /etc/udev/rules.d/50-tablet.conf:

Section "InputClass"
	Identifier "Tablet"
	Driver "wacom"
	MatchDevicePath "/dev/input/event"
	MatchUSBID "256:006e"
EndSection

I'm not so familiar with Xorg logs, so I'm not quite sure if I'm doing it right but since /var/log/Xorg.1.log doesn't seem to log much I only post the content of /var/log/Xorg.0.log.
This is what /var/log/Xorg.0.log logs when I plug my tablet in:

If there's anything else I can do to help debugging let me know, I appreciate.

@foobuntu, you seem to be missing a c in your MatchUSBID option value. I.e. you have:

	MatchUSBID "256:006e"

but should have:

	MatchUSBID "256c:006e"

You're also missing an asterisk in your MatchDevicePath option value. You have:

	MatchDevicePath "/dev/input/event"

but should have:

	MatchDevicePath "/dev/input/event*"

[spbnick]

@foobuntu, also, you should put 50-tablet.conf into /etc/X11/xorg.conf.d/ and nowhere else. Yes, create the directory if it doesn't exist.

Oh man....thanks so much, I was really blind for this. I don't know how many times I've been looking into this 50-tablet.conf, checked and rechecked it so many times, I didn't see it.
Summary:
I corrected the typos so now I got

Section "InputClass"
	Identifier "Tablet"
	Driver "wacom"
	MatchDevicePath "/dev/input/event*"
	MatchUSBID "256c:006e"
EndSection

stored at /etc/X11/xorg.conf.d/50-tablet.conf.
And with that I now have xsetwacom tool and X server working.
I really appreciate. Your work is amazing.
