USB mouse and keyboard not working

Any advice/thoughts/suggestions appreciated:
All 3 USB ports at the back of my iMac have stopped working. This means I can't use either a keyboard or mouse, so have no way of logging in. I turn my iMac on, it boots up as usual, but when it gets to the login screen, the mouse and keyboard don't work and I get a message about bluetooth set-up. (Both my mouse and keyboard are wired, not bluetooth).
I have tried an SMC reset (by turning the iMac off, unplugging all USB devices and the power cable, leaving the iMac for a few minutes and then plugging the cable back in a turning it on again). This didn't work.
I've also tried a different version of the SMC reset where I hold down the power button whilst all the cables are unplugged and also as I plug the power cable back in. After doing this, the fan turns on at full speed (v loud), but the mouse and keyboard still don't work.
I've also checked my mouse on a different computer and it works fine.
Has anyone got any other suggestions / workarounds?
Note I can't do a PRAM reset because my keyboard doesn't work.
Is it probably that the USB hardwear has failed? If so, is it possible to repair this? It is worth repairing given it is a 5/6 year old iMac (the white plastic one) which is probably on its last legs anyway?
many thanks!
Jez.

Try the SMC reset again, only this time wait 5 minutes in set 3 instead of fifteen seconds.
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds. 5 minutes.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.

the setup that works to me now is
automatic xorg.conf with the AutAddDevices False (disable hotplug) lines
dbus and hal enabled in deamons
this lines instruct xorg to use xf86-input-mouse/keyboard instead of evdev. ie it looks like with evdev there is no point in xf86-input-mouse/keyboard

Bluetooth Mighty Mouse and Keyboard not working in Win XP!

Hi All,
I simply cannot get my Bluetooth Mighty Mouse and Keyboard to work in Win XP via Bootcamp! The bluetooth icon appears in the tray and even shows that they are connected but they do nothing at all. One thing to note is that they show up as connected but with no password. Could this be the problem? If I reconnected the two with new passcodes for XP, would they still work when I reboot in OSX?

USB mouse and keyboard not responding

I had a power outage yesterday and my iMac was on. I have since tried to start it and my keyboard and mouse are not responding and I get a message that the date on my computer has gone back to before March of 2001. I need help, my hardware warranty just expired and I really don't want to take in it and have to pay $100! Also I put in my start up CD and now I can't get it to eject. Please HELP!!!!!

Does the keyboard and mouse work after the computer boots up? Try unplugging them and plugging them back in. Make sure to plug them in directly to the computer. If it still is not working try the mouse and the keyboard separately one at a time. Look to see is the caps light comes on the keyboard and look to see if the mouse lights up. To set the date and time go to your System Preferences/Date & Time and put a check in the box that says Set date and time automatically(assuming you are connected to the internet). If you can get this far go to System Preferences/Startup Disk and select the install disk as your startup disk and click restart. When it boots up to the disk, instead of going through the installation, click on Utilities at the top and run Disk Utility on your hard drive.

Bootcamp, Mighty Mouse and Keyboard not working

Hi All,
I just install yesterday Windows 7 (Ultimate 64bits) by Bootcamp in my iMac 21" (bought in 2013).
During the installation, the Mighty Mouse and the keyboard were not working (except the first W7 screens, selecting partition and language), and now, installation finished, i got to use an external keyboard to select username and password, because Mighty Mouse and Wireless Keyboard are not working with Windows.
I restart the computer using OSX and both are working fine.
Could you please help me?
Best

LENOVO Z51 MOUSE AND KEYBOARD NOT WORKING AT SAME TIME

I know this question has been asked before, but those solutions do not work for me. I just got my new Lenovo z51 80k60030us and I quickly put a game on it just to test out the waters. ran well. However, I can't move (use the keyboard) and look around (use the mouse) at the same time. I looked all over the internet and understood that it has something to do with "palm tracking" however no one had the solution for my specific mouse/keyboard issue. when I try and change the options under the lenovo mouse, it is grayed out. I tried everything to ungray it, but I have yet to succeed. help please??

Huawei e220 hangs on Mac Mini G4 and USB mouse and keyboard slow way down

I have a Mac Mini G4 running os10.5.8 My mouse and keyboard are a creative wireless combination that go to a USB hub then to the USB port on the mini. When I use my Huwei e220 wireless broadband modem, it frequently hangs when disconnecting, and the mouse and keyboard barely work. Activity monitor shows the CPU load is not very high at all, yet the mouse is almost stuck. If I put the computer to sleep, then it comes back and works fine. Its a bit of a hassle, and seems to be specific to the USB on the mac mini.

Is the modem connected via USB?

Touchpad and Keyboard not working (including external devices)

Hi,
I am using an rmbp with win7 and macosx.
Win7 on my bootcamp partition was working perfectly(4 months+) until now .I restarted my system and realized that the touchpad and keyboard are not working(inluding external mice/keyboard).I can boot into Macosx and the mouse and keyboard are working perfectly so its not a hardware problem.I havent set any restore points and have tried all the other recovery options (using f8 before booting) but to no avail
I have read some other solutions which involved opening the device manager but I cannot press anything when I login to windows.Does anybody have any idea except reinstalling windows? I would really appreciate any help !
Cheers

I have even loaded my Bootcamp partition in parallels ,in hopes of repairing the installation from there but Parallels give an error about mouse coherence and I cannot use my keyboard and mouse there .
Does anyone have any other idea except reinstalling windows ? .Thanks !

Apple wireless mouse and keyboard stop working ... now says OS X version and bluetooth incompatible

For no apparent reason my apple wireless mouse and keyboard stopped working. I was not upgrading or installing anything, the batteries are good, nothing was changed as far as I know. Now bluetooth discovers the paired devices, connects for about 30 seconds, the disconnects ... or stays connected but doesn't work.
What's happenned ... I'm rushing to finish a big job ... any ideas? I've tried re-pairing but doesn't work ... says that OSX version may be incompatible with device bluetooth ... I'm using Lion so maybe there is another lion problem?

Hello:
Barry: What do you mean with "making devices favorites"?
This is the method:
Go to system preferences>bluetooth. Highlight an item in the sidebar. If detailed information does not appear, click on the little gear and select show more info. Then click on the gear again and select favorite.
And how could an hardware-related problem be (temporarily) solved rebooting the OS?
Intermittent problems are, IMHO, most often caused by hardware. Restarting will occasionally "fix" problems - why, I do not know.

Brand new IMac 27 bluetooth mouse and keyboard not connecting for eight minutes after start up.

I have a new imac 27 that has worked flawlessly for three weeks.
All of a sudden, when starting up the mac boots fine but the bluetooth mouse and keyboard are non responsive. This state is maintained for between 7 and 8 minutes then both mouse and keyboard start working and continue doing so for the rest of the day....until the next restart and the whole saga repeats itself.
Both sets of batteries are fully charged.
I have scoured different sites and tried any suggestion that made any sense, to no avail. All I am able to do at the moment is to do the time, wait the 7 to 8 mins. and then all's good.
My first Mac and this is very annoying especially as Apple must be aware of this issue but no solution is forthcoming!
Any suggestions/workarounds would be great.
Thanks

if you are using rechargeable batteries sometimes they don't stay charged for as long as they should try using alkalaine batteries and see if the issue still persists.
also try doing an SMC reset, the following article tells how to do this:

Usb composite device is an older usb device and might not work in USB 3

I recently bought one Lenovo Yoga 2 11 laptop running Windows 8.1 (64 bit).
When I try to connect my old Brother MFC-3240C printer using USB (2.0), it doesn’t work.
Below are the steps performed:
Connected the printer to USB 2.0 port on laptop (on the right side). Automatically installed the printer driver (no exclamation mark beside printer icon)
When the printer didn’t print, I tried to use troubleshoot as below:
Control Panel->Hardware and Sound->Devices and Printers->Right Click on Printer Icon->Troubleshoot.
It came up with USB composite device is an older usb device and might not work in USB 3.0
Removed the printer and re-installed the driver. It is all the same.
Any help will be greatly appreciated.
FYI – the same printer works fine with my older laptops running Windows 7.

Already checked Brothers website for the printer drivre for Windows 8.1 (64 bit).
It says ... The built-in driver is already included with Windows® Operating System or is available through Windows® update.
So, installed the default driver for the printer that is available with Windows 8.1.
Even connected the printer with USB 3.0 port on the laptop, but it is all the same.

Are you connecting your iPhone directly to your PC or to a USB hub?

[SOLVED] Xorg and keyboard not working after upgrade.

Any hint?
How do you recover a system once it's gone like this? Many thanks in advance.

Just my 1.46¢
You're right, problem wasn't actually solved. In fact, yesterday I upgraded the whole system again and the same problem showed up, but I got it fixed.
Same scenario: after a boot (shorter than usual), what I had was a tty, but I noticed something that I hadn't noticed the last time: the prompt said "Arch Linux 3.11.[?]".
The kernel version was supposed to be 3.12.[?] so I started investigating and after several attempts, this is how I got the system working again:
1. Chrooted into the system
2. Wiped /boot
3. Re-installed grub
4. Re-installed linux kernel
5. Re-created grub.cfg
6. ???
7. Profit
I'm pretty sure that what originated the problem wasn't a "kernel issue" as I pointed out in my previous post, but it was an incorrect installation of grub: in fact, the grub prompt never showed up before yesterday, the system used to boot straight, ignoring the 5 seconds timeout.

USB mouse and keyboard don't work on HP Pavilion g7 2203sd, Windows 8.1.

It is not possible to use a USB mouse or keyboard on the HP Pavilion g7 2203sd notebook running Windows 8.1.
A wireless mouse used to work (already some time ago), but now wired or wireless mouse and keyboard don't work any more.
I have tried removing USB devices in the Windows Device Manager and let Windows detect them again, but it does not work.
I read somewhere that it might have to do with the xHCI USB controller that is installed.
I tried removing that and connecting the USB mouse but no succes.
I also looked for driver updates or something to disbale in the BIOS (like xHCI), but nothing found for that.
Can anybody help me with this problem.
Thanks!

IMac not recognizing bluetooth nor USB mouse and keyboard

The iMac I use has suffered a pretty annoying problem. I typically use a wireless keyboard and magic mouse with the iMac (I could be wrong, but I believe these both use Bluetooth technology). First, the iMac stopped recognizing these. They kept losing connection last Friday and then suddenly stopped recognizing them at all. Yes, they both have full batteries and blink to show me they are on and searching for the iMac.
Second, I tried using a USB mouse and a USB keyboard to get into the iMac and fix the problem. But neither are recognized by the iMac as well. The mouse is a Dell model that has a red light on the bottom, and it glows red for less than a second when I plug it into the USB port before going dark again and not working. So, I can't get into the iMac to fix the problem.
I've read a few other things on the community boards. I restarted the iMac. I unplugged it completely for several minutes and held down the power button for fifteen seconds while the power was unplugged. I've tried multiple mice and keyboards, all to no effect.
Is the iMac not recognizing the USB keyboard/mouse because it's still searching for the bluetooth versions that it will no longer recognize? Is there a way to fix this without setting up an appointment with the geniuses?
Thanks!

I'm having the same problem. It started happening on my Late 2012 model iMac 21.5" after applying the latest update.
What I found was that nothing seemed to work connected directly to the iMac. However, if you attach an externally powered USB hub, then all devices attached to the hub will work. It seems as if the USB ports are still working, but without power.
After I was able to get my USB keyboard to work, I was able to zap the PRAM (hold command-option-P-R while powering on) and then magically everything was back to working again. Unfortunately, this was short lived as the problem has resufaced again for me today, but you could give it a try anyway.
