Keyboard & Trackpad only work before booting, USB devices also not working
Hi,
Yesterday I installed MacFuse and NTFS-3G because I needed to store some things on an external drive for work. I rebooted as was instructed in the install docs and that's when things got ugly.
When on the login screen I've got no keyboard or mouse. Hooking up an external keyboard and mouse didn't work either, they didn't seem to be powered from the USB ports.
Odd thing is: I can boot to safe mode or single user mode, but after letting it boot I lose keyboard again.
Things I've tried:
- Safe mode: keyb not working at logon screen
- Single user mode: keyb not working at prompt
- Zapping PRAM: Can zap PRAM, but keyb not working at logon screen
- Resetting SMC: keyb not working at logon screen
So at first I thought this was a hardware issue (since USB devices don't get power), but since the keys work when booting up I start to wonder if it's just a software issue.
Any thoughts on this?
EDIT: I now hooked on a mouse befor being at the login screen and it seems to get power right up until the apple logo appears (until OSX is booting I presume?). So definitely a software issue? I'll try the setup disc this evening, but I don't want to lose any data. What's the best way to do that?
Thanks in advance, by the way!

Hi,
Same problem here after a reboot on evening of the 12th, i can boot into hardware test and no problems found, trackpad, keyboard and external USB working ok but when I boot normally, none of the above work.
I'm fairly new to MacOS but could boot as an firewire drive OK to get files off the machine?
Anyone have any starting points re drivers or prefers, I've done the PRAM, SMC reset etc, with no difference.
Thanks
Carlo

Macbook air built-in keyboard/trackpad only work at login screen
The built-in keyboard and trackpad have become unresponsive on my 2013 refurbished macbook air. When I restart it, everything works normally at the login screen, but becomes unresponsive again once I've logged in. The computer works fine with external inputs or a shared screen.
I've recently updated to yosemite. The fact that everything works up until login makes me think this is a software problem. I've tried all the troubleshooting steps listed here, and I've reset PRAM and SMC. Does anyone know what could be causing this?Hi,
I was able to get result from apple store after 24 days not hours days. They said it's my fault and they have found liquid inside of it and when i asked to see pictures of it they asked for COURT ORDER and repair will be cost around 400$.
I am %100 sure that my macbook air never touched with liquids.
I was using it for business and not even fluids there isn't any one scratch on it. I have been very careful.
Did they asked 400$ for you too ?
I am also using mac mini and iphone 5s. I think i will never buy an apple again.
And i will definetly go to court.

My Keyboard and Mouse freeze after connecting USB device
In the past few weeks I got this situation where my MacBook Air (13" Late 2010 model) would stop responding to the keyboard and trackpad after I connect a USB device (like an external hard disk, or even my iPhone).
I found one (quite inconvenient) solution: if I connect an external USB mouse and keyboard they work, and after a while the built in trackpad and keyboard start working again. But if I do not have an external mouse and keyboard around me, I am quite stuck and only a reboot fixes the situation.
Any idea what might be causing this, or if there is any solution? It is clearly a software issue, as the hardware can be returned to normal state after reboot.
Note: I have the latest OS - Mac OS X Lion 10.7.3 (11D50) and regularly update my software.I have the same issue, on the same model (late 2010 13" MBA).
I haven't been able to figure out a solution either. Strangely, I recently bought a USB external drive and it *never* causes a freeze upon connection. Only smaller devices (iPod, iPad, FitBit, USB stick) cause it. I need to reboot the computer with the device attached to be able to access it. -
W520: Unable to boot from USB - device does not show up in boot menu
I have a W520, and I am trying to boot from a USB key. The USB key is bootable, my old T61p boots just fine from it, and so does another computer I tried.
The W520, after pressing F12 on power on, immediately shows the Intel PXE agent and then some blue boot menu, which only shows hard drive and LAN as available boot options.
I have tried all three USB ports but the results are always the same - the USB device does not show up. Is there any trick or BIOS setting to enable boot from USB?
Thanks,
CSHello Neil
Thanks for getting back to me
The issue was that the usb drives were disabled in the bios from the Startup menu.
To enable
1. Enter bios
2. Select boot
3. If you do not see the boot device you require use the down cursor key until the "Excluded from boot priority order" becomes visible.
4. Select the device you require (in my case USB HDD)
5. Save and exit.
You can now boot from a usb stick and install the Linux distro of your choice :-)

G70-250US notebook synaptics mouse pad will not work & keyboard will only work until I log onto pc
I have a G70-250US model notebook with Vista 32. I decided to reload OS due to issues with mouse pad and keyboard. I still have the same problem whereby the mouse pad will not work and keyboard will only work until I log in and then it will not work. External mouse and keyboard will work fine. I tried uninistalling drivers for both and rebooting and letting OS find new hardware and install the drivers and this still did not correct. I even pulled down the synaptics driver from HP site and still not working. I checked the BIOS and it is the most recent. I am at a loss. Any ideas on these issues.
Ok I tested a bunch of different Firefoxes on my pos linux box.

I have an old Dell Dimension 2400 I plan to use as a replacement for the Sony Vaio when it pops. I've held out as long as possible because it lacks a pci or usb wifi and I really didn't want to run 50 feet of cat5 up a flight of stairs to it. [as i type this i think i remember where a linksys stick for it might be]. Yes I guess it's about time I just do that.
Don't laugh but the reason I held off adding a simple usb keyboard was just lack of space in my tiny bedroom. My setup is on two tray tables side-by-side. Sony Vaio is on left one, my lcd monitor and mouse are on the other. I barely have room to put a cup of coffee on the one with monitor and mouse let alone a full size usb keyboard lol.
Anyway thank you again for all your help. -
Are mobile internet USB devices still not working on Snow Leopard?
Are mobile internet USB devices still not working on Snow Leopard? I actually had to go back to my previous operating system to get this to work. I would however prefer to use Snow Leopard...if Apple & HUAWEI have finally got their act together!
There appears to be a problem with drivers for USB wireless modems with 10.6. I upgraded from Leopard to Snow Leopard and now can't connect to the internet with my wireless modem. I hope Apple sort this out soon. Or maybe it's Huawei that needs to put a 10.6 driver into its software.

BACK UP YOUR REGISTRY!!! Editing the registry can be (read: IS) dangerous and can cause no end of pain if done incorrectly.
- To Back Up your Registry: Click START menu and click RUN. Type REGEDIT. Click File, then choose Export and type a name for the Registry Backup, something like REGBACKUP012015 or whatever works for you.
- Click Export and let it export the registry to a file.
- To fix the issue: Follow the folder tree on the left to: HKeyLocalMachine > System > Current Control Set > Control > Class
- Find {EEC5AD98-8080-425F-922A-DABF3DE3F69A} down the LEFT hand side and click on it.
- Under the list on the RIGHT hand side find UpperFilters
- Right-Click UpperFilters and click Delete
- Close the registry editor and restart your PC (without the iphone attached).
- Once restarted and logged back in, plug in your iphone and voila! Windows will actually choose the correct driver. -
hi I recently dropped my ipod touch and now it wont connect to itunes. Everytime i plug it in, i get an error message saying that the usb device is not recognized
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I have a new IPod Nano and when trying to connect to my PC for the first time I get a fault message that says the "USB Device is not recognized by my computer. I have several other IPod devices and have never had this problem. When I go to windows explorer, the device does not show at all, so I cannot manually open it.
Hello JETaylor2015,
Congratulations on your new iPod nano! I would be concerned too if my iPod was not recognized by iTunes or my computer. I recommend reviewing this article for steps to take when your iPod is not recognized:

What do I need to do to get my cannon camera to upload pictures into iPad . When I plug it in system comes up connected USB device is not supported?
Use the camera's SD card instead.
Another way. You can use a USB flash drive & the camera connection kit.
Plug the USB flash drive into your computer & create a new folder titled DCIM. Then put your movie/photo files into the folder. The files must have a filename with exactly 8 characters long (no spaces) plus the file extension (i.e., my-movie.mov; DSCN0164.jpg).
Now plug the flash drive into the iPad using the camera connection kit. Open the Photos app, the movie/photo files should appear & you can import. (You can not export using the camera connection kit.)

the external GPS is used only for 911 but the device will not operate without it...this causes great inconvenience for me, having to run that cable to a window in the two houses I use it..is there a way to disable the GPS if I do not care about the 911 functionability..? this is the only downside I have with the network extender and it renders my device useless..
Nope, GPS is a Federal requirement for anything operating a cellular telephone signal. You don't ever plan to call 911 until you are in an emergency. I don't see that requirement changing any time soon.
If you are truly inconvenienced by the VZW network extender then perhaps you should disable you calling features in these areas and swap over to WiFi only. There are many services and apps out there that can route your phone services through internet service providers. -
HELP! In middle of upgrade to windows 8 and keyboard/trackpad stopped working!
Hey all, new mac user here. Just bought a new macbook air 13" 2014 model. I succedded in installing windows 7 via bootcamp via a usb drive and was in the middle of installing a downloadable windows 8 upgrade (at a preferences page when they ask you to select your favorite color) when my macbook's keyboard/trackpad stopped functioning. I plugged in a usb mouse and that would not work either. I have absolutely no clue as to what to do next. If I had to install some driver or thing please tell me how to cancel the windows 8 install and return to windows 7. Thanks for all your help strangers
I was not able to find any drivers specifically for the web cam. I did find software to use the camera, but that was all I could find.
However, I do have a question about the Windows 8 upgrade process that was used.
Did you do an in-place upgrade or a clean install of Windows 8?
Go back to device manager. Is there anything here at all in an other category indicating it is having some type of an issue?
There are certain events that will need to happen.
Go to the start screen and search for uninstall a program. Select this option in the settings category.
This should take you to the Desktop app and show the familiar uninstall a program feature from Windows 7.
Select add/remove Windows Components on the left.
Is Framework 3.5 checked here? If not, enable this and install it.
Then, install the HP framework which is needed for some HP programs. This is a Windows 7 installation, but it should go through.
http://goo.gl/jDI7X
Once that is finished, reboot the system.
Let me know what happens.
