There's a diode (probably infrared) and a receptor, one on either sides of the wheel, soldered directly into the green PCB. Wheel is SPOKED, and by turning it you interrupt light travelling from the diode to the sensor. No magic there.
Oh, and dust sitting in there can permanently block sensor from any light coming from the diode, so there's no way for it ...
To answer your edit and expanding AAronD's excellent comment, the direction is sensed by a microcontroller by the sequence of the codes when the wheel is turned.
For example, the two diodes, when turning the wheel, let's say, counter clockwise will translate to the following sequence:
For the clockwise direction,...
Try pushing down on the scroll wheel, it should click. I just discovered that the wheel toggles between a very smooth scroll and a more precise scroll. In my case, changing to the more precise scroll fixed the problem. It makes the scroll feel more like a gear than a roller ball. I think with the very smooth scroll, it tends to keep rolling and "bounce" ...
Better Touch Tool does what you want.
I've just downloaded it and am thoroughly enjoying it: http://www.boastr.net/
I believe it's also available on the Mac App store.
I had a similar issue with the Logitech M560 mouse on my MacBook Air. I LOVE this mouse! It has 5 buttons plus a tilt wheel, real rubber grips (not that spray-on stuff that gets gummy after a year), 1 year battery life and best of all... weighs a mere 92 grams with a Lithium cell!!! So awesome. But it's not Mac-Compatible at all and none of the third party ...
As the cause can be both hardware and software related, different measures have to be taken to examine the root cause of your cursor lag.
Seeing as your issue affects several peripherals, it is less likely that they are defective. It is however recommended to try to connect them to a different computer to exclude this as a possible cause.
Here's a solution that worked for me - go into Mouse Properties -> Pointer Options and tick 'Enhance pointer precision'. This causes pointer velocity to be consistent across screens with different resolutions.
I had exactly the same problem, just watched this simple video on YouTube.
Basically the steps are:
taking the black cap off
sticking a piece of paper inside making the contact points closer
stick the black cap back on
I tried it and it works.
I figured out a solution. I had Logitech Control Center installed, and it appears that something in either OSX or Chrome changed and broke some kind of interaction between LCC and Chrome (I had not updated LCC previous to this issue). When this began happening the first thing I did was install the latest version of LCC for El Capitan, but that did not fix ...
Since most Logitech gaming mice store the mouse profile and settings on the mouse, you can use a Windows or Mac OS to install the Logitech Gaming Software and configure your mouse how you want it. Once you're done, you can unplug the mouse and plug it into the Linux system, and it will still have the same desired behavior.
If you only have access to a ...
I am also using the MX Master and ran into this issue.
Open up your Logitech Options software and from the "Mouse" panel, click the white circle over the Thumb Wheel Scroll. This will bring up behavior options. Inexplicably, changing the behavior to "Zoom In/Out" seems to fix this horizontal scrolling issue (at least, I can confirm this for SSMS.) ...
Here's my fix, we've done 3 of these mice with this fix and it's worked each time.

Hope that helps.
I had the same problem, so I wrote an application to set mouse speed per monitor. Source code (C#) is available; it's in the same ZIP as the executable. The program works by changing mouse sensitivity when the mouse pointer crosses a border.

To map the thumb wheel to trigger a keyboard button you need to use an additional software.
How to remap buttons on the Logitech MX Master with autohotkey
If you are using Autohotkey you can remap buttons as you like.
A simple way to do remap the thumb wheel on the Logitech MX Master would be something like:
This requires ...
I did some research and found out that there are many types of scroll wheel types. It is not just Logitech , but almost all mouse manufacturers use this type of scroll wheel.The one here is optical scroll wheel. This uses a light shining onto a photodiode through slits in a metal or glass disc. Reflective versions also exist. This is one of the most common ...
The solution turned out to be very simple. As I learned from this Superuser post, Logitech's scroll wheels use a diode and receptor to recognize when the little spokes inside the wheel are turn. Unfortunately, if dust manages to lodge itself inside the spokes, it blocks the signal, preventing the action from being recognized for that particular turn.
I've had that kind of problems before, with a cheap mouse. The problem has to be in the scroll wheel, and opening the mouse with a little cleaning and checking the moving parts would help. Of course, if you are willing to go into that. Depending on the mouse, it may be hard to do, or nearly impossible without inducing damage.
Mouse acceleration is controlled by the Enhance pointer precision option in the mouse settings dialogue. The actual acceleration is controlled by a series of inflexion points along a curve, which are set using the SmoothMouseXCurve and SmoothMouseYCurve settings in the registry. You could try modifying these settings to get the mouse response that you're ...
I had the same issues when moving the USB dongle to the other side of the Mac Book so that the Mac Book was in between the dongle and the mouse. As soon as I moved the dongle closer to the mouse and connected it into a docking station with nothing in between dongle and mouse, lag was gone.
The answer given about the lens and light sensor being dirty solved my wheel issue.
For me the wheel was very lagged and usually took a full spin just to get a single response or sometimes it wouldn't respond at all.
Open the mouse (three screws under the stickers, and after removing the top cover the wheel lifts up and out. Be sure the lens and sensor are ...
Thanks for reminding me about this question by replying to it. It's my fault not providing the answer, which I had indeed found.
I sent the mouse back to the vendor where they tested it and confirmed there was a defect. I was given a new mouse replacement which has served me well for a long time.
It began to behave strangely again now, after nearly five ...
Thanks CharlieRB for suggesting I look through the Logitech support site, which I should have done anyway. I found someone with an unrealted issue to mine, in the fix for their problem, someone explained that by switching the mouse from On-Board Memory to Automatic Game Detection, many of the mouses media features / functions open up. I don't know what they ...
