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

it's a safe passage so they can once again reintroduce a new plug

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!

Open it up, look at the microswitch - it'll have a part number on it. Type that into Fleabay and they will sell you a new one for maybe 1 ~ 2 euro. Desolder 2 or 3 connections, drop the new one in, solder it up.
Double clicking is normally a switch bounce problem, and a new microswitvh will probably fix it - I've done it a few times now.

Gracias. Like fixing a finicky remote. Probably a better switch than those blister switches. A lot less annoying than the rotary switch on a clothes dryer, too, I'll bet.
A good thing about mice is that, unless it's a real specialty or real piece of junk, one gets used to a new one very quickly. Glad that it's not the old days of US$100/each for a (serial) mouse.

Or just buy a new mouse for $10.

And you get a ... $10 mouse.
Spend more, you get a better "feel", better plastic, better "weight". Better "click" as well, if you know what I mean.
I use trackballs, and you spend more to get 'em, but they last forever - except microswitches, which get clicked a humungous number of times ...

Actually, the $10 mouse has always worked great for me. I don’t get those weird shaped expensive mice.

You fixed your mouse a few times? So you're one who slams his mouse!

I did that several times in the days of the Atari ST. The old mouse still works fine to this day. microswitches wear out. You don't have to slam the mouse.
I have lived with several Zen masters - all of them were cats.
His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

Sounds like the microswitch for the mouse button took the hit. They are not expensive and easy to replace. How are your (de)soldering skills?

They used to be very good. Now, with many items not designed for any sort of attention other than replacement, how this will turn out is a good question.

A mouse should not be too hard to disassemble and put together again. I have the opposite problem at the moment.
There is a 3D printer model of the old Star Trek shuttlecraft and I am trying to convert it to a case for a little 8 bit computer that I have on the breadboard.

Opening a mouse is no problem - screws typically covered by the small slide-pads, and occasionally, also in the battery compartment.
The mouse was part of a refurb package with a nice keyboard (it was the may interest). Aside from the interest of what's inside this particular mouse, fixing it will compete with replacing it with another refurb (final cost of new switch and shipping costs). It has, after all, been replaced with a backup already.
Interesting: There are shows I like, including Babylon 5 probably the top; classic Dr. Who; I watch various Star Treks, which not only stream but also are broadcast 6 nights a week on a local stations (9-4). Except, of course, I never watch Captain Mommy and Voyager. That being said, I never had the urge to decorate via clothing or objects with their representative images and such. So many others do, and of course, they go to conventions and dress up and all.
Different strokes (as often said).
