when in air is it closer to the resiever

 

Well technically but I'm talking an inch off the desk and it will work fine. Heck, if I just tilt the top half off the desk it will work fine.

 

are you on a hill? I live in a 300 year old house which is on a hill and the house really isn't straight. If I have my mouse on a certain part of the mouse mat it will move by itself.

 

is this mouse under warranty? if not you could open it and clean it out.

 

I'll have to check when I bought it but would dirt be the issue? The ball is on the left of the mouse and the censor is on the inside right. I've taken the ball out and nothing looks in the way of the sensor and I don't think that would explain why it works fine if I pick it up.

 

well i dont know why just lifting it up would make it work right so was thinking maybe it was dirty inside.

 

Yea I don't either. It's super bizarre. I'll try taking it apart.

 

I'd suspect a receiver issue. Many of the new Logitech models use the new "mini receivers" which hardly protrude from the case and thus limits the useability area. I used a USB extension cable to move the receiver from the PC USB port to my desk near the mouse pad.

 

So you run a wire to fix a wireless problem.... niiiiice... Been there, done that, doesn't work for more than 1-5 minutes...

 

So I have tried 5 different m570 units, 7 different wireless dongles, two different OS's and 7 different computers. I have turned off all wireless, have cleaned, banged, tilted, rattled, cussed and replaced with new, and the problem never changes and never goes away. The only common thread is that the problem goes away when I do anything, but it comes back within 1 to 15 minutes.

The problem only happens on computers I own that have usb2, usb2+ and usb3 ports on the same computer. USB hubs make the problem worse. All of my computers are workstation class machines (even the laptops) so there is a fast machine with plenty of horsepower to "keep up" with USB. I think Logitech has a USB bus incompatibility problem, and the problem has been there for YEARS. They are in complete denial as to what the problem is... They blame dirst and wireless interference, but the problem is CLEARLY in the way they talk on the USB bus, as it affects my standard wired keyboard.

Itisnot a wireless problem, I have a spectrum analyzer that shows that when I turn off all of the wireless, no neighbor is visible with enough power to interfere (I'm in a house far from neighbors, and I'm an engineer thatwork s software QA with a background in wireless with all the test equipment to go with it... the only thing I don't have is a USB protocol analyzer).

When the trackball is messing up, it interferes with me typing on my wired keyboard. The faster I type, the more visible the problem is... The typing interference comes in the form of spaces and punctuation characters being delayed while text characters are not delayed, so they appear out of order. like the "Itisnot " in the previous paragraph. That typing interference is constant, and very annoying. The typing interference goes away when I unplug the wireless dongle.

Sure, cleaning the ball and socket fixes it for 1-5 minutes, the same as banging the trackball on the desk, or replacing it with a new one. Anything I do fixes it for 1 to 5 minutes, then it comes back. My wife keeps calling tech support, and they keep telling her to do things that don't work, and she gets mad and buys another new one. We must have $1000 worth of wireless logitech trackballs and keyboards.

So yeah, clean it, replace it, spend more money... The problem appears to be logitech.

 

Ok, so my wifetell s me thatth e M570 works fine on her computer at work.

(all of the above typos are due to the the logitech malware)

And she confirms that the computer she has at work is the cheapest, low end computer her boss could possibly buy... it is a used, low-end desktop system with only one kind of USB port. It was manufactured about 9 years ago. THAT one and only THAT one works with the Logitech unifying crap dongle in a successful manner.

So there is something about the usb2/usb2+/usb3 combination on newer computers, OR computers with big processors like Xeon's. Sorry, that is all I have at home, high-end computers. With LOTS of memory I might add, I have 16g to 64gig in all machines.

Logitech, fix your USB code... it is badly, horribly broken.

 

Funny, I've always liked logitech mice, but the last two I purchased started having problems shortly after buying them.
Latest trouble is a performance MX with the dongle which gets 'stuck' in whichever window I have open at the time. It works fine in the window, but attempting to switch to something else in the task bar, trying to close or minimize the window, moving to something on one of the other monitors or alt-tabbing to something else just doesn't work. If whatever I'm trying to click isn't in the stuck window, it doesn't even highlight when the cursor is on it.
If I plug in another mouse and switch to another window the MX works fine for a while then gets stuck again. does same with or without the unifying software installed and in w7, w10 and XP, in linux it works fine as a generic three button mouse.

 

If the case is blocking the receiver then it won't detect a signal. I currently use, and have used several of the Logitech models and the new receivers aren't even an inch long. They work fine in a laptop or if I put it in a front panel port, so it's obviously an interference issue with the port location on my case. So I used a USB extension cable to get the receiver up under my desk, and the problem went away.

I have several Logitech mice and keyboards and have never seen the problem that you describe. And yes, both of my current computers (my latest is a "high end" build) have USB 2 & 3 ports. I don't know what the problem is that you are having, but I'm not seeing it.

 

My computer actually sits 'backwards' on my desk so all the connectors, ports etc are facing me so it's a straight line of sight to the receiver.
Have to reach around to load a cd or hit the power button, but everything else is a lot easier to get to.

 

If my eyes aren't fooling me, this is a three year old thread that was bumped with a seemingly unrelated post which others have added to. So, I'll add mine.

I have (had) an M570 that just flat died overnight one night. Worked fine one night, dead the next morning. Not just the trackball, but the dongle too. I have another one (using it now) and tried to do some swaps to test the pieces. Nothing would make either the trackball or dongle work.

Tried their 'support' ..... completely useless. Both their forum and their direct support. Absolutely no help at all. Replies didn't even address my question or issues in any way.

I would tell them I tried a fresh battery and turned the power switch off and on, no green light. They'd reply in badly broken English -- 'please to try new battery, then cycle mains switch on and off again while observing green light' or some other nonsense.

I gave up.

 

Wow, you're correct it is an old thread, I saw it in the 'recent discussions' list to the right and clicked.

 

May as well keep adding to it

While playing around with my mouse to figure out how/why it was getting stuck, I uninstalled anything to do with logitech, then rebooted and had the same problem, only then my other mouse would get stuck as well until I turned off the logitech.
So I hit the registry and deleted every single key that had 'logitech' anywhere in it.
Everything on the mouse works fine now, only issue is that I get an unidentified hardware error on boot now.

edit:
it's also listed as a 'HID compliant mouse' now with a microsoft driver, definitely seems to be logitech driver issue.
