USB Mouse & Keyboard freezes with USB KVM after a while

Looks like connecting and disconnecting USB keyboard & mouse using USB hub causes some processes to freeze - the mouse and keyboard stop responding and you cannot log out or restart the OS X. Anybody else has the same issue?

I found what the issue was - it was not Apple or KVM, but logitech software that I installed to handle my trackball. Uninstalling the software fixed this issue. So the conclusion is - USB KVM works great with MacBook, but Logitech software is junk.

Mouse & Keyboard freeze

Please help... my G4 and my mouse & keyboard are not communicating. I have 2 other Macs in the house & the mouse & keyboard work just fine on those computers. I also have a wireless Mighty Mouse that doesn't work with my desktop Mac either...works fine on my laptop.
I can turn the G4 on & off, but cannot use it. I am stumped.
Thank you.

First, try lugging your keyboard into your other USB port. Try a USB device in that port. Is the port good?
Are you using a wireless mouse & kb? New battery?
Try starting up in Safe Mode

[Safe Boot takes longer than normal startup|http://docs.info.apple.com/article.html?artnum=107394]
Safe boot mode runs a directory check command similar to that used by Disk Utility's repair. In Tiger it ignores some stored information (cache) that is normally read that speeds up the boot process, and it moves some other caches to the trash. It also uses only System fonts and disables all Startup Items and any Login Items.
If that doesn't help then boot from you installer disc to run Disk Utility to repair your drive and permissions.

From BDaqua (couldn't have said it better):
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer (Edit: Do not use this disc if it is not the same general version as what you have currently on your computer, e.g. use a Tiger disc for a Tiger drive, not a Panther disc), then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
Then Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes."

VISA Read over USB Problem: After a while the xBFFF0015 Timeout Error occurred

Hi,
I have trouble using labview with my non-NI USB device:
The device is an analog input DAQ board. I was able to setup communication with the board using a VISA driver specifically created for this board and direct FW calls using the product's firmware specification provided by the manufacturer.
This method has been working pretty good so far, but when I try to get large amount of data (64k samples @100ksps), the VISA Read returns the 'VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.' error.
Please see the attached screenshot of the block diagram for details.
First, an 'analog input scan start' command is sent to the DAQ device, and then the vi tries to read all collected data from the device, once the right amount of data retrieved, or no more data is available the data collecting process (the while loop) ends and an 'analog input scan stop' command is sent to the DAQ device.
The data collection starts with no problem, but after a while, in loop# 400, the VISA Read hangs and then returns the error mentioned above.
I tried to increase the time out value, but it didn't help, the error occurred after the same number of loops, the VISA Read got hosed and the error occurred after the longer timeout expired.
I also tried to add some delays in the loop, but it didn't help either.
I am not sure what do I miss here and I would highly appreciate if anyone could give me some guidance how to solve this issue.
Thanks,
John

I just wanted to specify that this is not an NI board avoiding to make people think this is a hardware issue. And I think that the rest of the code is irrelevant in this case.
I believe that I don't use the VISA functions correctly. I assumed that someone who used these functions before would be able to point out the obvious steps missing in the data collecting process using the VISA functions.

Mouse not working with Boot Camp after 10.5.7 update

I upgraded to 10.5.7 recently, and now my mouse doesn't work on Boot Camp. It doesn't seem to register, and I can't move the pointer. I tried this with two mice that worked just fine on the Mac OSX side. Any ideas? Has anybody else noticed this?

I have a new (July 2009) iMac24 and neither the wireless mighty mouse nor keyboard work with Boot Camp XP Home Edition SP3. They install OK with the Bluetooth control panel, but then after five or ten seconds, drop out of the control panel and have to be discovered again. I spent two hours today with a Mac support expert, but no joy. We both gave up. It seems the wireless mouse/keyboard does not work with Boot Camp. If anyone hears of a solution, please let me know.

Macbook Pro Retina Mouse/Keyboard freeze

Hi there,
I have a 2013 macbook pro retina that's less than a month old. I have experienced a number of trackpad/mousepad freeze issues while using the computer. They occurred in close succession while using 10.93. I update to 10.94 and had not experienced the problem again since then(a week or more) but today it crashed. this is a big problem as i am a dj and use this laptop to play live gigs. I was hoping that you could help me isolate the problem. What happens is I will be working away and suddenly the mouse will freeze and the computer will become unresponsive, the keyboard doesn't work except for the power button.... also, the desktop background disappears upon forced restart.... any ideas? what may be causing this? Thanks in advance, Richard

If your machine is less than a month old, you should use your warranty and call AppleCare (you have 90 days of phone support) or take your machine back to the Apple Store (make an appointment with the Genius Bar first) and let them deal with the issue.
If yours is the 13" model, there is a thread on here (somewhere) about trackpad and keyboard failures when also using Bluetooth, I think (don't quote me on that - I don't have the affected machines so I don't follow the thread too closely).
But I do believe that Apple is aware of the issue and had 'fixed' it in either a patch preceding 10.9.4 or in 10.9.4 itself.
Give them a call...

Mouse cursor freezes a few seconds after start-up? Need help!

Laptop: Samsung Series 9
OS: Windows 8.1
Problem: since booting up my computer today, my cursor will freeze about 30 seconds after boot-up. Prior to this, I'll be able to move my cursor for a few seconds as I normally would, but then I will inevitably see the blue loading circle next to the cursor
and then my cursor will be frozen in place. I can still use my keyboard/everything else functions regularly. I decided to boot up my computer in safe mode and my cursor works fine. Clearly then, there must be some software/start-up issue?
I should note that I used my laptop fine yesterday night. When I booted it up today my cursor froze and I saw the restart prompt that said windows will restart on its own in 1 day to update. So I updated/restarted and the problem persists.

Hi,
Mostly, this issue is caused by third party services or programs conflict problem.
Please use Clean Boot to troubleshoot:

Keyboard freezing with new upgrade

I have had my phone upgraded for 24 hours, and the keyboard freezes every time I try to type something. It is not app specific. I have restarted my phone many times, along with syncing it with my computer. Syncing has resulted in an even slower phone and my apps not even loading. I really do regret the update and want iOS 6 back! Anyone else having issues with their keyboard, or know how to fix it? My phone is pretty much useless at the moment, and it's only 2 months old!!!

i upgraded my iphone5 to ios7 - experncing the same issue. keyboard freezes on all apps. it takes about 4 to 5 seconds for the text to appear and then freezes again.....
should not have upgraded... it is annoying.

Mouse/Keyboard issues with Mountain Lion

Has anyone had issues with mouse and keyboard functionality with Mountain Lion? I have two iMacs and a Mac Book Pro, but this iMac is the only one I'm having trouble with. First, ML somehow prompted Razer Nostromo drivers to stop functioning(just for macros). I just figured I had to wait until an update was released(which btw hasn't happened yet ) However, I also use the Razer Naga and I don't believe that the Naga is the culprit, but I could be wrong. For the past week or so when I single click, it registers as as a double-click. It is SO annoying. Has anyone experienced this? I have gone over all mouse and accessibility settings and nothing helps. I have downloaded the updated drivers and nothing works.
Thanks in advance for all responses,
Ashley

I didn't think of doing that, but I tried it and the problem does not occur when the right mouse button is primary. However, when I switched it back to make the left button primary, the problem returned. Would this indicate that it is a hardware problem or could it implicate the drivers as well? I suppose the mouse would make sense since I do not use this mouse on my other two items with Mac OS X. What do you think?
Thanks,
Ashley

Mouse+Keyboard Freeze and LOUD fan noise...

Hi,
Seems to be a few similar threads, so here we go...
Just got my iMac G5 20" 1GB Ram (OS 10.4.3) 2 days ago. All went well and suddenly, mouse + keyboard froze. About 10sec later, the fans kick iun, VERY loud. Never stopped for 2 hours.
If I reboot, shutdown and restart, do all the kind of troubleshooting you can read, it always starts again int he grey screen with the Apple and the fans at max revs, VERY nousy.
Eventually it goes away. But about 1 hour later, same story.
I ran the Apple Hardware test and all tests came PASS but there was originally a memory error POST/0/2048 notice. But the 1GB memory test passed...
Had a chat with the Apple Agent support, said this code shows a hardware component failure.
Have to bring back 10KG of EXPENSIVE Apple HW to the store tomorrow.
Great way to spend Xmas indeed
Any comments or suggestions?
Thanks,
JP

Hey,
When does this happen exactly? On Toshiba screen or Windows startup screen?
Are you running factory settings or another OS?
I think its hard to say why this happens. It could be software or hardware malfunction
Fact is you can test the RAM modules using Memtest86 or another diagnostic tool. You can ask Google to find it, its freeware. Just download an iso image and create a bootable CD/DVD. If you boot from this disk you can start the test.

Mouse/keyboard freezing machine around same time every day

Using a silver tower G5 here and around the same time every day for the past week I've had to power down the machine. The mouse and keyboard just freeze. About a week ago we did put this on a KVM to switch between this and a G4 connected to a SCSI scanner. The KVM has only PS/2 ports so we're using the Belkin Y PS/2 to USB adapters. The problem seemed to have started a day or so after starting to use the KVM but I'm not sure if this is related to the freezing problem. Here's what's in the Console around the time of the freeze:

Rob Kudyba-
Too many adapters. For troubleshooting purposes can you go with a mouse and keyboard connected as directly as possible?
Do you know what Adobe LM is? That seems to be buggering things up a little.
If you still have the errors after trying it with as few adapters as possible, try repairing your startup disk.

Imac freezes with gray screen after mavericks update

I was updating my imac system and it is frozen in a gray screen, like it is restarting.
It's been twenty minutes and it didn't restarted.
What can i do if it don't restart anymore?
All my work data is on that imac.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
     a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Mouse & keyboard freeze at startup

Hallo, sorry for my poor English, I hope made myself clear.
I've a problem with my mouse and keyboard (Logitech S 530 Mac cordless). They used to work very well, but from one day to the next, they work in login screen, where I can move the mouse pointer and write down my login password, but they freeze when the computer loads the start screen. Nothing happens forcing a boot. I can use them only if I unplug the power and then I plug it in again. I've set up the restart after an electric fall, so it powers up and all work fine. Could you help me? Thanks a lot

Your English is quite good by the way!
I's starting to sound like Hard Drive failure or at least severe HD corruption, see if it even shows up here...
"Try Disk Utility

Mouse/keyboard freezes?

Two questions. 1- does anyone else experience their mouse freezing? I was watching a movie and when I finished I closed the dvd player and the mouse was froze, and the keyboard wouldn't eject the cd? I then had to use ea shortcut. 2- is there a shortcut way to reboot the computer?

Do you have the Intel model? It is in one of your posts, but not the other? If it is, try posting over in this forum.
If not, try updating to 10.4.6 using the Combo updater instead of the delta update through software update.
Obviously backup all your data first, preferably by cloning the internal drive to a FireWire drive using SuperDuper. Then download but don't apply update yet. Repair permissions, unplug all USB and FW devices - except keyboard and mouse - apply update, restart, and repair permissions again.

Thinkpad Yoga Mouse / Keyboard freezing

Hello,
On my new TPY 20CD001UK the keyboard and trackpad seem to freeze very often. All dirvers are updated. The digitizer and touchpad continue working when the trackpad and keyboard become unresponsive.
Occasionally the keyboard will lag and dump all entered text after it unfreezes.
Is there any fix for this?

Okay... so lets focus back on the question. Why are we having lockups? I'm on a model with the SSD. It happened again, shortly after I posted my comments. It happened after coming out of sleep. Since there is no HDD indicator, one has absolutely no idea if there is HDD/SSD activity consuming CPU. So, you wait, and hope eventually the system will begin responding.

Bluetooth remote freezing with PowerPoint on MacBook Pro while idling

I am experiencing problems with bluetooth remote controls (3 different brands) freezing up when used with MS PowerPoint on a MacBook Pro running Snow Leopard (all updated). It is intermittent in nature and appears to be related to idling when giving presentations. It can freeze as quickly as within one minute to not freezing until 30-40 minutes later. This may not be a remote control issue as the arrow keys on the keyboard will not advance or backup the PowerPoint slides as well. However, when using my iMac computer without the remote, I have not observed the freezing (although, I may not have waited long enough since the nature is intermittent and variable in time).
When frozen, the mouse centered on the slide with a touchpad click awakes the computer to work properly (quick, but not ideal solution). However, when two screens are utilized (LCD projector or another monitor) via VGA connecion in "Presenter View," the touchpad click does NOT awake the computer, regardless of where the arrow is placed on screen. During this situation, the "presented slide" can be advanced by clicking the forward and backward arrows below this "subwindow" of "Presenter View," and even clicking on the image itself will advance it forward (but not backward). When this happens, the keyboard arrows do not work in advancing or backing up the slide sequence.
When in this frozen mode with a LCD or 2nd monitor, the only way I have found to get it working again, is to "Exit Show" and pulling down the "Slide Show" tab and selecting "Play from Current Slide." This takes me back to the slide where the computer froze and allows the bluetooth remote to start working again (obviously not an optimal solution, as the software should not disengage). Again, it appears if I keep changing to another slide within a few seconds to a few minutes, the PowerPoint does not freeze up. However, it is intermittent and variable as to the length of time before it freezes up.
NOTE: I have run these same PowerPoints, with the same remote controls, without any problem for hundreds of hours over the past 3 years. I have updated MS Office 2011, from 2008, last fall and have also run these same items without problems for about 40 hours. I have run Mac "Disk Utility" and just installed a MS Office "Update" released yesterday, which has not corrected the issue as well. Is this issue a MicroSoft problem?
Bless whoever who has an answer to this complex situation. Thank you!

I am having the same problem with a minister's MacBook Pro at my church. It started about 2-3 weeks ago. We at first thought it was a remote issue and found out that it is not. He is running a vitually new MacBook Pro with Mountain Lion 10.8.2 OS. He has Microsoft Office 2011. He has only had the computer since December. He runs powerpoint presentations all the time. He never had a problem until about 2 1/2 weeks ago. When he runs powerpoint in Presenter Veiw it would freeze up on him. You can still move the cursor over to the arrows on the presenter view slide windo and phisically click the mouse on the arrows to move forward or backward but none of keys on the keyboard work at all. It won't even let you escape. You have to move the cursor over the "Exit Show" button and click there. We thought that it might be just a presenter veiw issue so we tried running it in "Mirror Mode" and that seemed to work for a while but now we are having the same freezing problems.
We have taken the laptop to the Genius Bar and talked to the guys there and they did not tell us anything that helped us. They found this thread that you all started with our same problem. It looks like all of us had it happen at the same time. I find that very interesting. My minister said that he had not run any updates so we don't think that was the issue.
I have tried uninstalling Office completely and reinstalling it with all the updates and that did not help. I was thinking that I have a copy of Office 2008 here in the office and I was going to uninstall 2011 and install 2008 but one of you said you were having the same issue with 2008. Maybe I can uninstall 2011 and reinstall it without doing any updates and see if that does anything. We are very baffled and can't seem to get an answer about any of this from Mac or Microsoft. All we get is one blaming the other.
Let us know if this is helpfull or if you have any luck.
