The problem isn't USB-C, but B, B SuperSpeed, Mini B, Micro B, Micro B SuperSpeed, and then C. Maybe you want to count in as well the A, Mini A, Mini AB and Micro AB. Anyone who seriously believes that C will be the very last USB connector ever is naive, to phrase it politely.
Yet I'd say that for at least ten years, USB did deliver. Not only did we get rid of COM and LPT and SCSI (with umpteen different plugs) and PS/2 and DIN and 15-pin joystick port, but also several proprietary plugs that required dedicated extension cards plugged into the mainboard.
We could tolerate the Mini B. But it got out of hand with the Micro B. From then on, chaos reigns.

Since the computer mouse requires movement across flat surfaces the USB-C has to be twisted properly into the plug.
This is the expected behavior to support the hardware interface and is a part of USB-C requirement for all computer mouse(s).
Since keyboards are not moved across the surface they do not have this requirement.
A lot of people don't know about this, but the standard is clearly stated in the docs: http://gutenberg.org/cache/epub/10000/pg10000.html[^]

When I got my first USB-C device, I did the unbelievable and looked up the spec. (Yes, I know RTFM is a swear word, and I'm donning appropriate PPE.)
I was staggered at the complexity. The "major" signals, power, etc are "mirrored" (well, skew-mirrored) but some aren't. The device and chip-in-the-cable are meant to figure out between then which way is up. Maybe your extension isn't strictly "all pins 1:1", or its chip isn't playing nice.
Ah, the joys of "smart" cables!

When I got my first USB device (A Schock Flip Phone) I just returned the whole mess - I didn't want to have another device and charger when I've a dozen or so of the microUSB things that are everywhere.
Further reading and I discover that the base-turds are changing over, everywhere, and all the old chargers will require adapters.
So I went and bought back the Schock Flip Phone and go a ten-pack of really cheap adapater (micro USB to USB C) to sprinkle about my world.
The life-changing event suffered by Chris goes a long way in explaining why it sometimes doesn't seem to work. At least the microUSB only goes in one way - depending, of course, on how angry you are.

My USB-C extension cable has this helpful label stuck to it:-
"If there is a problem when connected with your mouse, keyboard, etc (USB 2.0 devices can only support one side), please reverse the female connector of the USB-C extension cable"
USB-C connectors are symmetrical, but this also relies on the USB 3 device detecting which way round the connector is. USB 2 has no such detection, as it's connectors were never rotationally symmetrical.
So I guess it's your USB 2 mouse not being able to detect the connection has been inverted.

Now that's interesting!
I'm actually using the extension so I can gaffe tape my USSB-C hub to the back of my monitor. The hub has a short USB-C cable so the extension allows it to reach my mac. I was assuming the (cheap no-name brand) hub would have all the smarts to handle all the bits and pieces around USB-C to USB 2 negotiations.
Live and learn.

Ah you youngsters. I never had such problems with RS-232.
"If we don't change direction, we'll end up where we're going"

As someone who deals with RS232, still, on a very normal basis, don't you remember the null-modem pin swaps? I still carry several DB9 null-modem adapters around with me in my backpack for testing. There is even a meme about it... something along the lines of "don't panic! swap pins 2 and 3 and carry on!" or something. So yes, even rs232 can be "backwards" (unfortunately).

Yeah, I think we had seven different ways of making null modem cables... That was including those on a full 25-pin RS232-plug with all the signals. On the 9-pin connectors, there were not that many alternatives.
My experience with them is primarily as a college lecturer: If you ask our students who were CS students in the first half of the 1990, they still remember one single group project: That of implementing a (simplified) Kermit protocol between two PCs, after soldering up a null modem cable. This was their first encounter with multi-process (and even multi-machine) software debugging: It gave them the greatest frustrations of their study years, but also their greatest learning experience.

It makes sense if it was dirty... which meant you overloaded the bandwidth but it worked with everything, EXCEPT THE MOUSE.

did you try a different cable?
If different cable works: then cable might not be properly wired up.
If different cable has same issue when flipping: the mouse might not be wired to handle the data and power on the flipped pins.
USB-a only has 4 pins.
USB-c has 24, 12 doubled.
The mouse likely switched from handle micro usb to C, so to save time and a penny cut the need to fully wire up all the pins

I flipped it. It worked. I moved on

I think I've dropped my mouse just one time too often, or once too hard. (LOGITECH M510)
It took a little while to realize it but it now frequently does a double-click for a left-single-click.
This is incredibly annoying - close one browser tab might close two, highlighting can be a major struggle. Many things seem broken because the double click does and undoes the change too fast to see.
In fact, the level of annoyance is incredible. I might open it up to see what's making it tick click, but even something as simple as highlighting a word to modify the font can be a multi-attempt challenge.
Well- now to find a compatible mouse for the multi-device dongle this is linked to.
[edit]
Good - found a working M310. Not compatible with the multi-device but I had it's dongle in the battery compartment so life is good-er

Dropped? Or slammed on the desktop when code didn't behave properly?

No desk here - just a nice rocking swiveling recliner and one 52" TV acting as the monitor.
The drops happen when I stupidly put the mouse on the arm of the chair when I get up and it typically gets thrown when I sit down if I don't grab it first (stupid rocker aspect of recliner).
(My boss uses two 65" or 70" TV's as monitors and relaxes on his couch). Clearly I need a raise in pay!
