USB keyboard issues

I'm running Mac OS X Lion v10.7.2 and have bought an extended USB keyboard, although I can't get all the keys to work properly (none of the function keys, end, etc)
I'm running the lastest software so what's the issue?
Thanks

first of all....thx for the help Xmad
ok...just to clarify...I am not using a usb headset...they are analog with a usb power connector actual model is Turtlebeach x12's..
I think I have found the culprit. I unplugged all my usb devices from the back of the pc (nothing is hooked up to the front usb)....The sound stopped when I unplugged my NVidia 3d emitter.....I plugged it back in and the sound started again...looks like it is doing something to my head phones....the sound was still coming out of my headhones even though I had pulled out the analog connectors from my sound card. so the sound is coming from the usb connector somehow...any ideas what is causing this of if I can stop it
thanks.

Bootcamp and iMac Thin USB keyboard issue....

I work at a university where we have several labs that are setup with iMac's that have been made dual boot for obvious reasons. Everything has worked without a hitch, until the upgrade from Leopard/Vista to Snow Leopard/Win7. Since upgrading, most of the computers still work, however we are having issues right now where the Mac keyboard will not respond until the computer is up and running. We can no longer do ANY key commands prior to loading into the bootcamp OS Picker. Beyond that, whenever we try to run Win7 on a handful of machines, the computer goes to a black screen asking which OS we would like to run with only showing the valid Win7 option. Normally choosing this option would cause Windows to load, however, the Mac keyboard still remains unresponsive. If we plug in ANY other branded keyboard, this screen doesn't appear, and Win7 loads just fine.
Upon getting into Windows/Snow Leopard, the keyboard works just fine.
Does anyone have any ideas as to what could be causing this? Is it a setting that we have missed somewhere along the lines? Has someone or something possibly altered the way EFI responds to the keyboard?? What could be happening? It is very puzzling that ANY other branded keyboard has no problem, but any of the Mac Thin USB keyboards we try all have the same results....

After some more testing, it appears to be an issue with the bigger aluminum USB keyboards with the number-pad on them. We have replaced the keyboard with one of the small aluminum ones (sans number-pad), and we now have all the EFI key commands working again. We have also tried a Dell and a Gateway keyboard, and these all work as well, we can even get these to trigger a Net-boot.
Apparently there is something that is drastically different with the "Large Aluminum Keyboard with Numeric Keypad" that is causing it to not work as intended. Everything was fine UNTIL we boot-camp was installed and now this specific "style" of keyboard is not working. We have tried 3 different keyboards of this style, and they all yield the same results of nothing.
Now poses the question what do we do, as EVERY Mac that we own has the "Large Aluminum Keyboard with Numeric Keypad". At this point, it seems like my only other option is to contact Apple Care and see what could be causing the problem....

Solaris 10 x86 b63 USB keyboard issue

Hello. I am trying to install Solaris 10 x86 on a Dell Optiplex SX280. The system uses a USB keyboard and mouse. When asked as to the type of installation to perform (1 - Interactive, 2 - JumpStart, 3 - Text Only), I select 1, then the system start booting and the following messages are displayed:
Configuring devices.
Using RPC Bootparams for network configuration information
ioctl (kbd type): Invalid argument
and hangs at this point. The keyboard stops responding so that a power cycle is the only option. Obviously the keyboard is recognized for me to select option 1 above but something happens after that. Any ideas? Thanks.

At the "1 - Interactive, 2 - JumpStart, 3 - Text Only" prompt the BIOS handles the keyboard. This is before the
Solaris kernel is loaded.
After the Solaris kernel is booted, either the Solaris PS/2 keyboard driver or the USB keyboard driver has
to handle the system's keyboard. For your system it's apparently the USB keyboard driver.
I'm not sure what's wrong with this system. You could try to boot into single user mode with verbose
kernel messages enabled. At the "1 - Interactive, 2 - JumpStart, 3 - Text Only" prompt, type
b -vsAre there any (error) messages from Solaris' usb kernel modules? Look for messages from the modules
"ohci", "uhci" or "ehci". ehci is for USB 2.0, while ohci & uhci are for USB 1.1 devices. I guess your
USB keyboard is an USB 1.x device, so you need either a working "ohci" or "uhci" driver for the USB
port where your keyboard is attached.

Non Apple USB Keyboard Issue

Hi All,
I recently purchased an L3 Systems WristPC keyboard to use with my mac mini.
The problem I'm having is that the NumLock key won't toggle and, as the keyboard shares the number keys with the qwerty row, I cannot type any numbers.
I've confirmed the keyboard works by plugging it into a pc where it functions as expected.
I've been all up and down the net and every forum I could find, but have had no luck with a solution.
Anyone?
Thanks in advance..

Hi Sound Speed-
Greetings and welcome to the Apple boards
Is this a USB keyboard or an adapted PC model?
If it isn't USB per se it most likely won't play nice with any Mac. Does it worked on a PC with the USB adapter?

USB keyboard issue

Hi,
I'm pretty new to *nix and I'm trying to install Arch for the first time but I'm struggling to get past the first hurdle, any help would be really appreciated.
I've written the iso to a USB drive as per the wiki but I cant boot because my keyboard isn't working in the very first menu.
The same keyboard and image on a different machine works fine so I guess this is something to do with the motherboard, 'Asus P877-I Deluxe', yep it's UEFI but it's booting in legacy mode.
I guess it's irrelevant but the keyboard works fine in an ubuntu live image.
These are the options in the BIOS under USB config:
Legacy USB support Enabled
Legacy USB3.0 Support Enabled
Intel xHCI Mode Smart Auto
EHCI Hand-off Disabled
Thanks

Haha no worries pal I know that feeling. I guess I can just workaround this problem by using chroot from an ubuntu live CD, is this likely to make installation more complicated? Like I say I'm not very experienced with *nix. I'll give it a go see what happens.
Thanks

G5 dual 2ghz. Been unplugged for a while. Powers up but no video or power to usb keyboard. Boots up fine in safe mode, restart into normal mode ok. After shutdown, back to same issue. What's happening?

G5 dual 2ghz. Been unplugged for a while. Powers up but no video or power to usb keyboard. Boots up fine in safe mode, restart into normal mode ok. After shutdown, back to same issue. What's happening?

I keep seeing people ask and the advice to replace if it has been unplugged, but really have nothing to confirm that from my experiences.
My experience is that a weak or dead battery can cause much more than date and time issues.
I have seen it time and time again.
Deal with used machines and you will quickly learn....
I'll give no "recipe" or set list of symptoms, but the range of irregularities that can occur make it a quick and easy first line of troubleshooting, especially when the machine has been off the mains for a few months.
Why fight mysterious maladies and troubleshoot with the knowledge that the PRAM battery is beyond it's useful life.
Maybe they recharge?
Not likely. They are chemically nasty, disposable, one way discharge batteries.
They aren't Lithium-ion batteries

ThinkPad USB Keyboard with TrackPoint issues with scroll (55Y9003)

Hi Guys,
I am having issues with this keyboard...
I ordered it to use it on my work where I have Dell Vostro desktops.
However scroll simply doesn't work in all programs and even stops working ... I also using VM and it doesn't work at all in VMWARE even if you point inside it it still operates at host system !? Weird...
I have installed latest drivers 1.01 but nothing... So when I removed all drivers and just keep default scroll work as default but still not in all programs and not in VM Ware, etc... Just to be clear my regular mouse scroll works in all and works properly...
Is it possible that this keyboard will work only on Thinkpads used as external keyboard ?
There are two things to be installed when I start a disk one is driver and second one is some interface driver which can be only installed on Thinkpads ?! Couldn't be that that thing is missing when running on non Thinkpad systems?
Any help how to make scroll work in all programs?
Thanks.
Moderator edit: Removed UltraNav from the title. This keyboard just has a TrackPoint.

I have the ThinkPad USB keyboard on a non-Lenovo desktop, and it works.
Yes the keyboard driver installs, but not the Lenovo System Interface Driver, for obvious reasons. All the buttons and TrackPoint work.
Yes the TrackPoint does not scroll in all programs. Search the community for "trackpoint scroll fix" and you will come up with instructions on how to fix this.

External ThinkPad USB Keyboard with TrackPoint issues with scroll (55Y9003) and hotkeys on a x201

Hello
Once more there is a glitch with the drivers for this external keyboard 55Y9003.
I have the drivers:
16.2.19.13 for the ultranav system of the x201
1.10 for the external keyboard
My system is XP sp3.
The keyboard of the x201is fine relative to the one 55Y9003.
The scrolling is set to standard for both systems.
Please do not advise to select smooth; it is not a solution and the smooth scrolling has been systematically utterly unusable.
The issues:
-the hotkeys on the external keyboards are not all working:
basically, fn+f4 and fn+nmlk work but the rest does not (say fn+f8)
-the scrolling of the external keyboard is not at all identical to the scrolling of the x201.
For instance, in pdfs viewed with foxit for instance, I have not a problem to scroll horizontally with the x201 starting with the hand tool.
WIth the external keyboard, whan I press the middle button to activate the scrolling, it remains the hand tool, I can scroll vertically but not horizontally.
FIrefox as also issues whith the middle button.
-the external keyboard still suffers from the sticky shift key.
I know the x201 and the 55Y9003 are no longer fashionable, but Is there some directly guy working at Lenovo who could help ?

My external Apple USB Keyboard letters doesn't work, but the numbers do. Why and how can I fix this issue?

My external Apple USB Keyboard letters doesn't work, but the numbers do. Why and how can I fix this issue? Also, When I open the Keyboard Viewer, the letters will highlight only if I hold the modifier key(s) "Control" or "Control and Option". I really need help with this. I don't have any other computer to try it on, so I will have to test it on a friends computer sometime. But perhaps solutions that I can try right now? Thanks.

I have a Mac Pro 5.1 and after a power outage my usb ports on the back of the tower do not recognise the apple usb keyboard upon start up. If I leave the plug out and then insert the keyboard after start up it works fine. The same happens with the front usb ports. How do I fix this issue?

USB Keyboard module reset issues [SOLVED]

Hi,
Im on a fresh install of Arch, and had none of these problems on the exact same setup one day ago.
Basically my USB keyboard outputs a message to the console/dmesg every second saying: "usb 1-1.4: reset full speed USB device using ehci_hcd and address 5"
If i "rmmod ehci_hcd" then the problem stops, but this reverts my devices to USB 1.1 mode, as soon as I "modprobe ehci_hcd" again the problem persists.
Anyone got any ideas of the causes/fixes for this issue?
Ive tried moving it to a different usb port, makes no difference.
This is the latest kernel on x86_64, and I get the same problem on the Arch live/install CD. My USB keyboard has a usb2.0 hub in it as well, but on a fully up to date system yesterday I didnt have this problem. This is just a clean reinstall (with LUKS encryption added).
Thanks
Jack

Hi, I am really disapointed over the lack of technical knowledge that you find these days in the internet. Linux was created first with maximum tuning capabilities. Then going mainstream they cut out all options leaving you basically helpless.
There are two problems to slow USB-performence.
1) Wrong configuration -> I assume that is not the case
2) Dumb Linux settings you can't change, because nobody tells you were to change them.
So the usual problem is, that the USB-Stick is mounted as "write-through" and not "write-back". So reading from the USB-Stick is cached, while the writing is not!!! Cache is a technique to speed things up, by not doing them in the order they appear. Especially with small files, there is no alternative. That is why modern harddisk have 8 or 16 MB cache on board. This way preformence of read/write files of size 0,005 or 0010 MB stays acceptable. USB-Sticks don't have an extra cache. The computer is supposed to take care of that.
Linux mounts USB-Sticks as "write-through", so with no caching in the writepart. So if you write many very small files, you can make a coffee break. Advantage is you can take out the stick after writing finishes without having to fear lose of data. With "write-back" you only know if the copy operation finished, that the data made it into the cache. To be sure, that the data also makes it onto the USB-Stick you need to unmount the USB-Stick.
Now everybody understands the problem. The big distributions prefer less speed rather than to have complains of Newbies that Linux corrupted their data - while the truth was, that those Newbies took out the USB-Stick without unmounting it.
So far so good, if those LINUX Expert would have left an easy accessable swith to change the "cache write policy", as windows does.
SO TO ALL THOSE LINUX EXPERT, PLEASE TELL ME WHAT I NEED TO DO TO CHANGE THE CACHE POLICY FROM WRITE-THROUGH TO WRITE-BACK. PLEEEEEEEEASE.

Apple USB keyboard with iBook defeats keyboard inputs - software issue?

A couple days ago I bought an Apple USB (corded) keyboard for use with my iBook G4 running 10.4.10. At first the keyboard seemed just fine, but I think I may have hit some key combination with it that defeats the letter functions of both the built in keyboard and the usb keyboard. The number keys and function keys seem to work fine, but the letter keys are switched to other functions (for example, some of them input blank spaces). It also changes the way the mouse functions - I have to hold down the control key for it to "click." The lack of functionality returns as soon as I plug the keyboard back in before powering on.
The problem persists after I unplug the usb keyboard, and only a cold reboot works to restore normal function to the onboard keyboard. My impression is that this is a software switch I somehow toggled, or the usb keyboard is just bad. I've tried toggling num lock, but that doesn't appear to be the issue.
Thanks for your input.

This is a hardware issue having to do with the USB connection of your keyboard. The mouse could still work as you are plugging in into a seperate USB bus. It would be wiser in my opinion to purchase another keyboard rather then investing any money in potentially fixing it.

How can I use a USB keyboard with my Macbook Pro?

My MBP will not recognize my brand new USB keyboard.
I have tried the keyboard on two other Macbook Air's and it works perfectly.
My MBP:
OS X Yosemite
10.10.1
Macbook Pro (Retina, 13-inch, Late 2013)
2.4 GHz Core i5
8GB 1600 MHz DDR3
Mac HD
Graphics Intel Iris 1536 MB
Thoughts on how I can resolve this issue would be greatly appreciated.
Thanks,
Greg

Brenden,
Thanks for the reply.
I've gone your suggestions in detail and the keyboard is still not working.
From what I can tell this is a known issue with Yosemite.

Someone at Apple must be able to figure this one out.
