usb mouse not working with Yosemite, help!

I've been reading theses solutions with great interest as I too suffer from the erratic behavior of my Logitech Nano VX mouse. Here's a solution that I literally just stumbled on that may help someone. My mouse came with a USB extension cable (I suppose any USB cable extension would do). I had originally placed the USB receiver on the left side of my MacBook Pro and when I upgraded to the new MacBook Pro with Yosemite, I put it in the same place which yielded a wireless mouse that just would not behave. so I placed the receiver into the extension, placed it directly in front of the mouse and the mouse is, so far behaving appropriately. I'm hoping that it continues to do so until Logitech or Apple or both can figure this thing out. Hope this helps.

I'm having the same issues with SteerMouse that I'm having with my Logitech Unifying drivers for my M570 Wireless Trackball. Both my Logitech drivers and SteerMouse do what they're supposed to do. I haven't had any problems whatsoever with getting my input devices to work, but they're interfering with a USB digital audio converter (DAC) that I have connected to it. Whenever I use one of the mouse buttons that I have mapped to a keystroke, my audio skips. If is press those mapped mouse buttons a few times in rapid succession, my DAC will crash and I'll have no sound until I either turn it off and back on again or I switch my sound output in the Sound Preferences to something else and back again.

It's definitely the drivers that are doing this and not the devices themselves. I use SteerMouse to drive some high end mice that I have that don't have Mac drivers. Since I started running into problems, I went into my Windows partition to properly configure one of these mice in Windows so I can stop using Steermouse and the audio/USB problems disappeared.

Ok, it dawned on me that maybe SteerMouse alone was the culprit so I disabled it and everything worked fine on my Logictech trackball.

Then it dawned on me that maybe SteerMouse has been updated. It indeed had been so I installed the latest version and my input devices are playing nicely with my DAC again.

All stupidity mine...

very same problem here...

I had the Logitech m705 plugged into a USB 3.0 hub. I was experiencing massive and inconsistent lag, the mouse would work fine for a little while and then become unusable. I removed the unifying receiver and plugged into a side usb port on the MBP and the lag disappeared. The hub only had USB 2.0 devices attached to it. It became very apparent just how much lag there was after the unifying receiver was plugged directly into the MBP.

I hope this issue is fixed since I only use the mouse when the MBP is in its Henge Dock.

Late 2013 27" iMac with OS X 10.10.3

Using Performance Mouse MX

The 'unifying software' never recognized an attached USB mouse, BUT

the Logitech Preference manager functioned just fine

...until just now

It sees the mouse, reports battery status

but WILL NOT configure

Well, everything BUT mouse tracking speed has already been configured - I wanted to bump up the tracking speed as I've gotten used to the higher sensitivity.

Tried restarting (just for the heck of it?)

The Logitech software is at its current level. (not backrev'd)

-shrug-

I have the receiver plugged into a port on my additional Thunderbolt monitor - which I believe are USB 2.0 ports.

Already had tried USB 3.0 previously.

All buttons functioning as configured (Copy, Paste, Select ALL, Delete)

Would be nice if the unifying software would 'see' the mouse, though!!!

I suspect this is Apple's fault - not Logitech's!

Hey I finally found the solution to your problem! What you will want to do is restart your mac and before the screen turns grey, hold down the command, option, p, and r key. Make sure you keep holding down the keys until you hear the start up sound twice and the problem is fixed!

Apple wireless mouse in Yosemite behaving erratically, all of these were factors:

1. Over time, tension in battery terminals diminishes, causing intermittent connection - insert piece of foil beneath base of each battery.

2. Repair disk permissions in Disk Utility.

3. In Bluetooth settings on toolbar, disconnect mouse and reboot.

3. Try alternative mousepad, using solid black neoprene "Steelseries" pad, somehow affects optical signal.

I have OS X 10.10.5 and have this problem as well. I have a Microsoft Natural keyboard and Logitech Trackman trackball connected to a USB 3 hub that is plugged into my mid 2014 15" MBP. I spoke with Apple Genius Bar phone support on Friday, did a full PRAM and SMC reset, and the problem persists. Console logs show USB connection problems. Worst case scenario for me and I loose my laptop keyboard and track pad as well, necessitating a hard-reboot. Some indications that uninstalling the Logitech Control Center (3.9.2 which is the latest) might solve the problem, but I haven't tried that yet.

Console log may provide more insight into the problem: look for events near the point in time when your mouse is plugged in and again when it stops working. For me it works for 5-30 seconds, then stops. I can un-plug and re-plug the USB hub in and eventually it will keep working.

Essentially Apple released this crap OS without even the basics of testing. Wireless mouse does not work? Really, the main interface with their OS and they did not test to see if their customers could interact with their own computers?

Horrible Apple, horrible.

i had the same issue ! My MX Performance doesn't work ! ( first didn't scroll the pages and then doesn't entirely work )

i reinstalled the control center of logitech mouse from logitech.com

Then i visit this pages ! i fixed the mouse issue !
