The only hypothesis I can think of to explain this is RF noise originating from the mother board. Any separation from the back panel or port, by even an inch or so, appears to completely eliminate the stuttering problem. So, it appears when the Unifying receiver is either plugged into the back panel USB port or placed flat against the panel with the port, the stuttering problem returns to some degree. I bought a 90 degree adapter only because I could not find a straight one for just extending the port out an inch or so away from the back panel. Third, with the USB Unifying receiver still plugged into the extension cable, I let the receiver hang within a few inches from the back of the motherboard back panel and not a hint of stuttering.įourth, I purchased a 90 degree USB adapter plug and plugged this adapter into the USB port and the Unifying receiver into the adapter. The stuttering problem returned but only to a very minor degree.
Second, I plugged the Unifying USB Unifying receiver back into the extension cable but placed the receiver flat against the motherboard back metal panel just adjacent to the USB port it was previously plugged into.
(The extension cable also used this same port) This inspired me to do some experimenting.įirst, I plugged the USB Unifying receiver back into the USB port it was previously connected to and the stuttering problem returned, just as before. I was curious how far the Unifying USB receiver needed to be separated from the back panel/USB port. The mouse now works perfectly with not even the slightest hint of a problem. I am assuming this distance is enough to get the thing out of the RF noise "Near Field". I took a 36" high quality USB extension cable and relocated the Logitech Unifying receiver about 24" horizontally to the side of the computer. The total energy emitted I believe is regulated by law and indeed very small but, relatively speaking, must be high right on the motherboard as is the location of the USB connectors that are part of the motherboard. I think it is very reasonable to assume any motherboard is an excellent source of a lot of RF radiation at multiple frequencies and a Fourier Transform wet dream of wave forms.
I had the Logitech Unifying mouse plugged into a USB 2.0 port on the back of my machine in a port integral with the motherboard. Coincident with this I stumbled on an article about RF interference and USB wireless devices and the light bulb suddenly lit. This mouse sucks because the two buttons on the left side are so incredibly sensitive I kept inadvertently jumping between browser pages. So, I threw in the towel last week and bought a hard wired Logitech M500 USB mouse. A call to Logitech tech support got a woman in the Philippines with a heavy accent, scripted only knowledge, and chickens loudly clucking in the background (honestly - she verified she worked from home and the noise was indeed chickens). I Googled the problem and found a ton of stuff going back a number of years referencing this exact problem with Logitech wireless devices but nothing I found proved helpful. Sometimes no problem, sometimes the mouse was unusable, but a problem at some level most of the time. I immediately noticed the cursor would momentarily freeze and the extent to which it froze or stuttered varied with no obvious connection to anything else. I've seen older posts about this but none seem to provide a definite answer so I'm trying to ask it once more.I recently started using a Logitech MX Anywhere 3 wireless mouse using their tiny USB Unifying receiver.
Logitech mouse lagging mac#
I can't believe I'm gonna have resort to a corded mouse for the mac when my linux setup can handle it just fine.
Logitech mouse lagging pro#
I'm using a 2019 Macbook Pro 16 running catalina(10.15.6) with a Logitech MX Anywhere 2s wireless mouse and it keeps stuttering every half a minute or so.
