Usb mouse constantly disconnects/reonnects

After the boot camp update to provide audio support for ear phones, I have noticed that my wired usb mouse occasionally disconnects and reconnects with a "de-dunk" sound. Any thoughts? Also this is happening on windows 7.

Greetings Beth,
Wireless devices are susceptible to interference. Review this article for common sources: http://support.apple.com/kb/TS3048#5
They are also very sensitive to low power. Make sure you are using VERY fresh batteries. If they have been sitting on a shelf for months they don't count as fresh IMO.
Troubleshooting steps to try after you read that article at the top:
Remove the following to the trash: Macintosh HD > Library > Preferences > com.apple.Bluetooth.plist
Restart the computer and re-pair the mouse and keyboard
If issue persists reset the SMC:http://support.apple.com/kb/HT3964

Magic mouse constantly disconnects and can't get it to connect without rebooting the computer. Anyone else have this issue

How do you solve the problem of the magic mouse constantly disconnecting? I have changed the batteries and turn it on and off, but the only way to get it to reconnect seems to be re-starting the computer. Any thoughts? Thank you.

USB Mouse Keeps Disconnecting on 13" 2011 MacBook Pro

Hello!
My Logitech M100 USB mouse keeps freezing up and/or completely turning off - constantly! About every 5 minutes, the mouse just shuts off (the laser at the bottom even turns off) and it becomes no longer operational. To fix it, I have to unplug it and plug it back in. This solution is good for another 5 minutes.
Every time my mouse disconnected, I noticed this pop up in the console:
1/15/12 8:27:32.000 PM kernel: USB Optical Mouse::terminate(kIOServiceSynchronous) timeout
And, if this is relevant at all:
1/15/12 8:29:10.000 PM kernel: 0 0 AppleUSBCDC: start - initDevice failed
I am running Mac OS X Lion.
Any ideas?
Thanks a ton in advance!

Does the mouse work on other computers?

USB mouse keeps disconnecting

My USB mice keeps disconnecting under Mavericks. It cuts out for so long that the only solution is to unplug it and immediately plug it back in. That solves it for a short while. If I am in system preferences it will intermittingly say no mouse is connected. It is a Logitech mouse and I have even removed the Logitech drivers as these were having the same problem.

I uninstalled the Logitech drivers and it still did not fix the problem. So I guess I will have to wait till there is an update to Mavericks. With the the problems with iTunes not detecting app updates as well, it will probably be a big update.

USB Mouse Constantly Freezing

With more and more frequency my Logitech MX-Laser cordless USB mouse is freezing.
It seems that when I have it connected via my powered USB hub, freezing occurs regularly. If I connect directly to the computer the problem seems to disappear.
I know that this problem existed in previous versions of the OS, has it been solved with 10.4.8? In other words, am I the only one having these types of problems?
Any help/suggestions would be appreciated.
TIA,

Hey Barrett_killz,
Welcome to the forums
I would suggest you trying out a different USB mouse and see if that helps
Cant suggest anything else as you have already uninstalled and installed the Drivers

G570 USB mouse cursor freezing constantly

The problem will be explained lower but let me tell you how this was.
So I've had this problem like 1,5 years ago, after I bought the laptop. So I bought a cheap mouse for it back then, and I noticed that the laptop had problems with the USB mouse, fine, I thought it was the poor mouse, so I bought another cheap one, and it worked fine. Then I bought a gamepad, and again, this problem.
Today I bought a gaming mouse, and the problem re-appeared. I've been searching through the internet all day long.
Basically, the mouse cursor freezes constantly, also with that "plugged-unplugged" sound, but the touchpad works.
I've been looking all around, tried the mouse on another laptop and it works fine.
I've tried:
- Starting the laptop in safe mode.
- Uninstalling/reinstalling the realtek USB reader or w/e its name is.
- The device manager trick (I think you know what I'm talking about)
- Been changing the OS many times after I bought the laptop, that problem persisted with the gamepad.
- Tried different ports around the laptop.
None of them helped. BUT, I saw that actually it hangs when the CPU is throttling. I've changed my power plan to energy saver and the problem went away. I've changed the maximum/minimum CPU power, the problem went away.
But the frequency sets constantly at 800 MHz. What can I do to keep it at 2200 MHz (i3-2330M clock speed) and also keep the mouse working well?

USB mouse disconnects when laptop on battery

Hello,
I am using Gnome 3.6 on 3.6.10-1-ARCH. Whenever I run my laptop on battery power, my external usb mouse disconnects after some inactivity period. If I plug it to external power source, it again starts working fine.
I suspect there must something in gnome 3.6 (weird optimization) or something to do with laptop-tools which disconnects the usb mouse after some time of inactivity to save power. How to fix this.
I referred this link, but it did not provide me way to fix this.
https://bbs.archlinux.org/viewtopic.php?id=49503
https://bbs.archlinux.org/viewtopic.php?id=149530
Update: I noticed that I had not enabled laptop mode tools so problem must be with gnome3. I have now enabled this and set my USB mouse id in blacklist, so that it does not autosuspend. Still It is getting auto suspend.

I imagine that your usb ports control is set to auto... which will suspend the device after a time of inactivity. The solution would be to have this not set to auto... though I am not sure how to do this with laptop-mode-tools in place. I don't use laptop-mode-tools, and it is my opinion that it actually makes things harder when you encounter things like this. Instead of learning where the configuration for this is within /sys and then creating the necessary configuration to change it, you now learn where it is in /sys, what is changing it automagically for you, then you have to learn the intricacies of that particualr power management tool.
So although I cannot help you with yout laptop-mode-tools, the file that sets this is /sys/bus/usb/devices/usb[1-9]/power/control or /sys/devices/pci0000:00/0000:00:1a.0/usb1/power without the symlinks on my machine for usb1.
Just my opinion, but with the power that comes in computers these days (for the past several years in fact), having something like laptop-mode-tools is pretty worthless. If you just have all the settings set as though it were on "battery" all the time, I bet there would be no discernible difference. I know I cannot tell, and then my computer probably charges ever so slightly faster because it is not set to consume more power when I plug it in.

Satellite L20: Can I disconnect devices like USB Mouse without turning power off?

Hi, all.
I'm an owner of Satellite L20 notebook. I have always turned power of my computer off when i need to connect or disconnect any USB Device. Some devices have a special icon on the taskbar to disconnect them but some doesn't (USB FDD or flash disks). Can I disconnect and connect devices like USB Mouse or Scanner wihtout turning power off?

Hi
Of course that you can do this. Because of that there is Safely remove Hardware option. All external devices connected on your unit should be listed there. If you want to remove some of them click on it and click on STOP button.
When the selected device disappears from the list you can remove it from the port. I have done this many times with different units and external devices ithout any problems.

Why is my USB mouse disconnecting and reconnecting?

Our USB mouse has been disconnecting and reconnecting intermittently. There doesn't seem to be any rhyme or reason for it. We're using a Logitech Optical Mouse. It doesn't seem to matter which USB port it is plugged into. Occasionally when it becomes unconnected and doesn't reconnect, unplugging and plugging it back in will "fix" it. I've been using HardwareGrowler to keep track of this. This was occurring before we updated to 10.7. I may be imagining this but it does seem to occur more when it is running hot.
Thanks

I have yet to try a different USB mouse to see if it is the mouse itself. I did plug in my iPod and there seems to be no problem with connection there. The mouse will disconnect regardless of tempature and it seems to disconnect more during heavy usage (gaming).

Macbook pro Late 2011 13.3 inch i7 keyboard and trackpad not working bluetooth showing a cross sign and no usb mouse is detected. Almost dead keyboard and mouse. Earlier same problem used to be solved by opening the lower cover and closing it.

My macbook pro 13.3 inch i7 late 2011 edition has previously encountered unresponsive trackpad and keyboard. To solve that, I used to open the back cover and then close it. It has been working fine since that. Yesterday, same thing happened, this time I noticed that bluetooth icon is showing a cross sign across it and keyboard and trackpad were unesponsive. After some time , everything worked fine and bluetooth sign was back to normal. Then , suddenly it went back to the problem. I shut it down by holding the power button. When I booted it again, I could not login because keyboard and trackpad were not working. I attached a HP mouse it didnt work. I opened the back cover disconnected the battery and then connected it again, didnt worked. Since then , I have tried many things and nothing has solved the problem.

@sanjampet
As you suggested I reset the smc, in the first boot nothing worked. In the second boot, it all worked like a charm. I thought that my problem is resolved now. To test it, I shut it down properly. Next morning, I powered it on, all things i.e, keyboard, trackpad, bluetooth etc. worked and I thought that problem has been solved. When I was just going to visit apple forum to reply you, the same problem reappeared. A sawtooth cross over bluetooth icon, keyboard not working, trackpad not working,no usb mouse working which worked well when it was fine. I reset smc so many times again and again but same problem continued. Isn't it a problem of the firmware?
Next time when it will work, I will update its firmware.
My macbook was bought in dec2011 so no warranty now.

My external usb mouse no longer works on my dv7-3085dx.

My HP Pavilion dv7-3085dx, running Windows 7 64-bit, is having issues recognizing the external usb mouse. Normally the mouse will work a few seconds to minutes before the computer makes the sound that the usb has been unplugged (even thouugh it has not) I have tested the mouse on all the usb ports and on several other computers to make sure it wasn't an issue with the mouse cord. Furthermore, I have tried using several different usb mice with the same results. I have also tried using other usb devices on my laptop (e.g. usb storage devices and cooling fan) with no issues to their performance and no usb device disconnect sound. Any help would be greatly appreciated as using only the touchpad makes gaming more of a challenge than I'm ready for.

Hi,
As per the issue you have mentioned it seems like the HID compliant mouse had been disabled .
Try to open device manager (Click on start type in device manager in Search programs and files click on device manager ) and that will open new window device manager go to Mice and other pointing devices click on the small arrow next to Mice and other pointing devices check to see if there is a down arrow on HID-compliant mouse if found right click on it and click on enable which will enable the Usb mouse
If you find the above steps help you resolve the issue please click on kudos.

USB Mouse autosuspends after 2 seconds

Hello dear Community
I have a problem with my USB mouse on my laptop. It autosuspends after 2 seconds when my laptop is on battery power. When AC is plugged in, the mouse works without problems normally. But sometimes (I couldn't find any underling rule for this behaviour) the mouse autosuspends also after 2 seconds when power IS plugged in.
First things first:
lsusb yields:
Bus 002 Device 003: ID 8087:07da Intel Corp.
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub

So the Mouse I am talking about has the ID 045e:00cb
After unplugging the mouse dmesg gives me:

I thought that laptopmode tools is the reason for the problems, so tried the advice posted on this blog. I made a udev rule
[nikolai@niko-arch ~]$ cat /etc/udev/rules.d/91-local-rules
# Add rule to turn of autosuspend for specific mouse
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="045e", ATTR{idProduct}=="00cb", TEST=="power/control", ATTR{power/control}="on"
and changed my laptopmode tools settings:
[nikolai@niko-arch ~]$ cat /etc/laptop-mode/conf.d/usb-autosuspend.conf

# For more information, consult the laptop-mode.conf(8) manual page.

LM_AC_SUSPEND_USB=0
NOLM_AC_SUSPEND_USB=0
# USB Auto-Suspend timeout in seconds
# Number of seconds after which the USB devices should suspend
AUTOSUSPEND_TIMEOUT=2
But I experience still the same issue (after rebooting and unplugging the mouse).
Then I tried to completely disable laptopmode tools with
CONTROL_USB_AUTOSUSPEND="0"
and rebooted, but nothing chances.
Maybe I am missing somthing obvious. Thanks for any hints!
Best Regards
Nikolai

Hi!
I got the same problem with my external mouse/keyboard here: https://bbs.archlinux.org/viewtopic.php?id=166517
I tried what you posted, brebs but it also did not work. If I change the power status using powertop my output of your script correctly says:
1-1.6 auto 480 Integrated Camera
3-1 auto 5000 Elements 1042
4-1.2 auto 480 USB2.0 Hub
4-1.2.2 on 12 Microsoft® SiderWinderTM X6 Keyboard
4-1.2.3 on 1.5 USB-PS/2 Optical Mouse
4-1.2.4 auto 480 USB2.0 Hub
but only with my 91-local.rules, which are basically the same as athal postest, the output is:
1-1.6 auto 480 Integrated Camera
3-1 auto 5000 Elements 1042
4-1.2 auto 480 USB2.0 Hub
4-1.2.2 auto 12 Microsoft® SiderWinderTM X6 Keyboard
4-1.2.3 auto 1.5 USB-PS/2 Optical Mouse
4-1.2.4 auto 480 USB2.0 Hub
of course i did udevadm control --reload.
it's somewhat annoying to have to start powertop everytime when you boot your pc with attached external mouse/keyboard.
Note though, I do not use laptop-tools, I do the rest of my powermanagement with udev rules, too.

Mac Mini crashes when connected to USB mouse!

This problem just happened all of the sudden--I came into my office a few days ago and there was the multi-lingual screen of death telling me I needed to restart my computer. Tried numerous times, no success--same message.
Took Mac Mini to Genius Bar--they said it checked out just fine.
Brought it home, plugged everything in--same problem!
Started eliminating USB and Firewire items that I was connecting to it. Narrowed it down to my Verbatim USB wireless mouse. When I disconnected it, the computer booted fine. However, can't navigate anywhere w/o a mouse, so I figured my solution was to just go buy a wired USB mouse.
Bought wired USB mouse. Same crashes! My computer will not boot with any USB mouse connected and when I connect a mouse after it is booted, it crashes the moment the mouse is connected.
Even if there is something I could install or uninstall, I can't do it because I have no navigation w/o a mouse!
Error messages on screen of death have to do with "kernels" and what not--again, if it was something I could replace/reinstall that would be great, but how can I do anything w/o a mouse?
Please help!!!
Thanks,
Phil

I have three 2008 model Mac minis, each with verbatim mice. Luckily one hasn't been upgraded to 10.6.8 because I'd be without a working desktop machine.
The 2010 Mac mini doesn't have this problem.
So far I've tried four different USB mice and all of them lock up the machine, even in safe mode.
I can't afford to go and buy three apple Bluetooth mice - it's the only way I can use these machines.
I hate downgrading machines, so I'm hoping apple supplies a patch soon.

[SOLVED]I can't use my usb mouse after updating kernel to 3.15.5-1

Hi~
I have a problem with using my usb mouse.
Well.. I'm using laptop and there are two usb-3.0 ports.
One of them is worked correctly, but other is worked only with usb storage device.
When I try to connect usb mouse and keyboard, it won't work at all. ( nothing is printed out with dmesg )
I googled about this issue, but I couldn't find o.O...
Is it problem with kernel ? or hardware!? How can I fix this ?

Well.. I executed pacman -Syu, so most system packages have been updated.
Anyway, I got new dmesg when It pasted few minutes after booting system.

I found some articles from ubuntu and they said it caused by usbcore because it tries to use 'new' usbcore scheme.
And the solution in there is
echo Y > /sys/module/usbcore/parameters/old_scheme_first
but it won't work. ;(..
