USB keyboard suddenly not working

My A1243 keyboard has suddenly stopped working at all. It also doesn't work when I tried it on another mac. However, the mouse that I attach through the USB port on keyboard still works through the keyboard.
Is this a settings issue? Do they have batteries? Has it just died?

It's possible it gave up the ghost, most USB keyboards do not use batteries like BT devices.
Try a SMC reset:

Follow directions for your machine for a battery you should not remove yourself, or a battery you can remove.
Also try with a different USB keyboard, that will give you a pretty good idea.

Apple USB keyboard does not work with one internal usb port

Hi everyone,
hope someone can help me to solve my problem. I have a MPB13 retina late 2013 since something like 3 months. I have additional screen (dell), usb wired keyboard (apple) and BT magic mouse.
Since a few days, my usb keyboard does not work well. It only want to work properly when plugged to the rights side usb port internal port and not anymore on the left one. It also work on a usb external concentrator. Before, I had no problem, it worked perfectly. There was no problem such as cofee on it...
After searching the web on such problem, I tries a few things such as:
I tried the keyboard on another computer (windows): works fine
I tried usb stick and external DVD reading on the left internal usb ports: works fine
I switch the MPB off and turn it back on: the usb keyboard still does not work on the left usb port
I tried the SMC and PRAM reset : nothing
Any idea ??
Thanks
Guillaume

Hi and welcome the forum!
Try uninstalling all USB hub devices from the device manager and reinstalling them again, particularly the keyboard's.

My Macbook Pro keyboard AND USB keyboard will not work. However, the trackpad and USB mouse will work. Any help?

My Macbook Pro keyboard and USB keyboard will not work. However, the trackpad and USB mouse will work. Any help?
This is quite frustrating, since it randomly occured as I was browsing the web. It seemed to happen out of nowhere. I cannot login to my user account because I cannot type my password.
Any help will be appreciated.

If you have another Mac, boot the non-working one into Target Disk Mode (holding down "T" at startup). Hook up the two Macs via a Firewire cable. The non-working one will mount on the other Mac as an external Firewire HD.
Next, download the 10.5.6 Combo update from here:
http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx1056comboupdate .html
Run it. When it asks you for a destination, choose the other Mac that was mounted via Firewire. When it's done, unmount the computer and restart it. The keyboard and mouse should work now.

Apple USB keyboard does not work

I have the same problem as described by Sweboss on November 15th, 2012. The Apple USB keyboard is working perfectly, but if I shut down the computer, when I switch it on again, the USB keyboard does not respond, and the computer is looking for a Bluetooth keyboard (which I had before). I have tried switching off, unplugging all peripherals, then unplugging the computer, waiting 15 seconds, then plug it in, wait 5 seconds (this is a remedy proposed in other mails). Switch on and the USB keyboard does not respond. It is not that particular USB port, as it works perfectly well with other peripherals like my scanner, or printer, and changing ports does not help. And when I tried it last time, I had no other USB peripherals connected. Can anyone help?

That is definitely some strange behavior, good to finally be working, but does not explain exactly what causes the behavior. Could have something to do with the energy saver part of the operating system, or a miscommunication with the USB bus itself. With multiple USB ports it would be good to test on different ports to see if that is an issue. Anyway, it is working now and that is good.
Another I don't know why but it works: a couple months ago a user was having problems with a wireless keyboard. The keyboard-iMac communication resulted in random charaters, time lag, and other bad behavior. The user finally found by accident that turning the keyboard off, removing the batteries, and then spending about five minutes just pressing keys, placing the palm of the hand on the keyboard and pressing, just pressing and pressing, and then replacing the batteries and turning on the keyboard, it worked fine. Seems like it is necessary to just force the keyboard to discharge all of the key switches. Those keyboards use capacitance switches instead of mechanical switches. So they retain a charge.
While that was a wireless keyboard, I wonder if that was what happened in a way with your keyboard...the unplugging and leaving it for a period of time, any charge may have dissipated and it would work again. If this happens again, try the above procedure and see if it helps.

Airport Express USB printing suddenly not working

Hi, we have an airport express which doesn't seem to be working properly. We've had it at least 2 years now. All has been working fine but suddenly USB printing is not working on it. When I load up AirPort utility and go to the printers tab, it says "USB printers: None". It didn't use to say that! I've checked the printer - it works fine when printing direct from computer to printer over USB (hence both the printer and the USB lead are fine). We use the airport express for iTunes and it works fine. The airport is running version 6.3. We used to print (when it worked) from both Windows computers running XP and from macs running Snow Leopard...
Any thoughts?
Edward

Erm... help!
In a bid to try to sort out the problem myself, I decided to restore the Airport Express (b/g) to the factory default and see if that helped... I did this through the airport utility. The airport reset fine and I then went through the set-up wizard. However, when it then tried to restart as part of the setup process, it said that there was an error and that it could not restart. It said to restart the airport utility and try again. This I did but it cannot see the airport. If I rescan, it says the same thing (unable to find any apple wireless devices). What should I do?
All thoughts and suggestions gratefully received!
Edward

Apple aluminum (USB) keyboard is not working at all in Vista

I just brought a apple aluminum (USB) keyboard. it works fine under Leopard. But when I plug it into Vista. Vista tells me keyboard driver install correctly, and device is working, but none of the keys on the USB keyboard is working. I mean not even "abc".

As I installed Windows on my Mac, I was unable to use my wireless keyboard and mouse (which are the standards from Apple) when i was operating on the Windows partition. I had to call my buddy and use his keyboard and mouse, which were not wireless, and it worked fine. While in Windows, i did download Mac OS X, to make the two OS compatible, but the wireless still did not work on Windows. Is there something additional i need to do to allow my wireless keyboard and mouse to work on the Windows side of things. Please let me know if you have the answer

Sound and USB ports suddenly not working

I have HP pavilion dm3-1103au which i bought about 3 years ago.. Everything was worked fine since the first time I use this notebook until about 3 weeks ago when I used it to watch a film suddenly the sound changed to noise sound and then my notebook sound not coming out at all from speaker and headset.. Then I restarted my notebook and then the sound working normally but after a moment the sound stop coming out again..
I check my sound driver to see any updates but it say my driver are up to date.. Then I go to sound control and test my speakers but it shows a warning that says "the device is being used by another application. Please close any devices that are playing audio to this device and then try again." I dont know what application that is using the sound because it happen when I didnt open any app..
After about several days later, the problem seems to became worst.. All USB ports suddenly have a problem too.. My USB mouse stop working at random time.. Then I try to insert my flashdisk and sometimes it can be recognized but when I try to copy files to my flashsdisk, it disconnected when the process of copying has not finished..
when i go to device manager the 'standard openHCD USB Host Controller' have a warning sign.. I check for updates but it says the driver was up to date.. So I try to uninstall it and restart my notebook.. but it didnt solve the problem..
I have reinstall and upgrade my windows from windows 7 to windows 8 but it still have the same problem and become worst.. now the sound not coming out at all from the speakers and headset from the windows starts.. Please help me.. I have no idea what cause the problems.. I think it's not hardware related..

Hello lynz00,
Did you check out this page to see if your computer has been tested by HP with Windows 8, prior to upgrading to Windows 8?
HP is not going to support hardware for Windows 8 on any system purchased before Oct 1st 2011. I realize your issue began prior to upgrading to Windows 8, but don't think the upgrade is the way to fix it.
Did you backup everything in Windows 7 in order to downgrade, prior to upgrading to Windows 8?

Bootcamp 3.x. USB keyboards are not working for the Windows XP Installer.

I'm running an iMac with OS X 10.6 and bootcamp 3. I am trying to use bootcamp to install Windows XP on a partition. When I get to the windows setup program the USB keyboard is non-functional, which is unfortunate because I need to hit 'enter' to proceed with the install.
I've tried multiple keyboards, and every USB slot on the iMac. I've checked for software updates, but alas I'm stuck.
Thanks.

Got a copy of the WinXP 7 Pro install disk with SP2 (genuine) hoping that maybe the sp2 disk may have better usb support. iMac wont read the disk just spits it back out like it has a bad taste, this is just getting to be comical.
Anyone had luck with Ghost imagineing in boot camp via BartPE?

USB keyboard shift keys suddenly not working

For some reason, when I woke up my MacBook Pro this morning, both shift keys on my aluminium USB keyboard were not working. I'm using the keyboard with a Magic Mouse and LED cinema display connected to my MacBook. When I hold either shift key in combination with any other key, either nothing is typed, or there will be random characters typed, occasionally.
I ran AppleJack on auto to see if there were any problems. There were a few preferences it corrected, but nothing major was wrong. I connected the keyboard to a friend's MacBook Pro, and the shift keys did not work on his machine either. Caps Lock does work. I've tried canned air. I don't remember spilling anything on it.
Any idea about what I can try to get it working, or is it broken? Thanks,
-Jeff

Try resetting the PRAM. Info here:

Wireless keyboard suddenly stopped working - changed batteries still did not help

Hi
I have an Envy 20 all in one touchscreen with a wireless keyboard which has been absolutley fantastic until now. The wireless keyboard suddenly stopped working while composing an email. I replaced the batteries and checked them with a volt meter to ensure 1.5v. They are a name brand alkiline battery. I tried re-booting the computer and pressing the blue connect button under the keyboard. The only keys that seem to work are the volume up/down and mute; the rest of teh keyboard does not. Any idea? I like the factory keyboard so I am hoping it is not a faulty keyboard. After market keyboards will use a USB port.
Thanks
Thor

I understand that your wireless keyboard is not working and you are looking for assistance. I am providing you with an HP Support document: Wireless Keyboard and Mouse Troubleshooting, which will walk you through the troubleshooting process for your wireless keyboard.
Now if this does not work and you have to replace the keyboard do not fear you can replace the keyboard and the dongle without using another USB port as the one that is in can be replaced. I would be happy to assist you further and/or walk you through changing out the dongle from a new wireless keyboard, but first I would encourage you to post your product number for your computer. I am linking an HP Support document below that will show you how to find your product number. As well, if you could indicate which operating system you are using. And whether your operating system is 32-bit or 64-bit as with this and the product number I can provide you with accurate information.
How Do I Find My Model Number or Product Number?
Which Windows operating system am I running?
Is the Windows Version on My Computer 32-bit or 64-bit?
Please re-post with the requested information and I would be happy to provide you with assistance. Thank you for posting on the HP Forums. Have a great day!
