CDROM Motor as a USB Controller - Is it possible? Answered

Thanks for the replies. Sorry, I will try and explain better...I have dismantled a few CDROM drives and stripped out the stepper motors that move the lens around. I wanted these to make a mini laser engraving machine (which I have all the parts to do now, but that's another project)I am also making an arcade cabinet and was looking to make my own 'spinner'. The spinner acts like a mouse but with only 1 axis. I figured that it should be possible to use the CDROM stepper motor as some sort of input controller, but getting it's electrical output converted to a digital signal is completely beyond me. It will require some sort of USB controller board obviously. I would be surprised if it was impossible to do.I asked the question partly because instructables was asking for suggestions/challenges and maybe I posted in the wrong place.Something like this USB joystick controller board in the images is what could be used to get a signal to the computer. It is quite basic and accepts on/off signals from microswitches in a joystick (left, right, up, down, fire etc).The bit I have no idea about would be getting a stepped on/off signal from the motor(generator) to the board when the motor(generator) was being turned. It would also be critical to know whether it was being turned one way or the other.Once that signal gets to the board (assuming the board is fast enough to read the fast on/off signals) then it is down to the program running on the computer to do what it will with that information, and that part is not what concerns me here.As you can probably tell from my terminology, electronics is not one of my strengths :)And yes Jack A Lopez, using a stepped motor as a stepped generator. Basically that's what I'm asking how to do and if it is possible to know when each step happens and in which direction. :)

Maybe you didnt describe it well enough? What exactly do you mean by the name "USB Controller"? I understand by this a chip which controls multiple USB-Ports ("USB-Hub") and that would not be possible with an electromechanical motor.
Another way of understanding is that you want to use a motor as input-Device which is used to control something in a software... Something like the old slotcar-controllers (https://i.ebayimg.com/images/g/JxYAAOSwuVpcyM9N/s-l300.jpg) but with a motor turned into a generator as input-sensor sort of?

Please explain in other words what exactly you want to accieve...

Your topic almost makes sense.

Semantically, it seems like a proposition of the form:

If a dog can wag its tail, can a tail wag its dog?

I am not quite picturing what you mean by, "...possible to use [CDROM motor] as [USB] controller"

Perhaps you are asking about, "motor as generator"

https://www.instructables.com/howto/motor+as+gener...

I mean, that would make sense, if you think "power" and "control" are the same thing; e.g. powering a thing is the same as controlling a thing.

Not possible at all as far as I am aware....
Sorry.
