Mac OS 5.8 usb external keyboard not recognised

I ordered a new mac keyboard and hooked it up with my Kensigton Trackball but they are not being recognised by my macbook.
any clues?
Thanks,
Steve

From searching the web, I am tempted to say the Iso Gear is quite an exotic device.
It's up to Astone them to deliver a firmware upgrade for their device to work with Mac OS X 10.5, as Apple probably follows USB 2.0 standards when accepting (or not) an external hard drive.
diskutil became more picky in 10.5 (been bitten myself) but still, I am not sure whether this is due to Apples development teams faults or due to to Astone following standards.
There has been an issue in 2006 with LaCie drives on OS X 10.4 which were resolved by their firmware upgrade.
I know this is of no help to you, but consider not just talking on Apple forums about this but also on Astone help channels.

  • Mac Mini first boot and bluetooth keyboard not recognised

    Hi Apple Support Community-
    I have just purchased a brand new Mac Mini and App Wireless Keyboard.  Unfortunately upon first boot, the Mac Mini is requesting I connect my bluetooth keyboard by switching it on, however even though the green light flashes, after the 5 second startup acknowledgement, there is no response from the Mac Mini.
    To confirm the keyboard is working, I have successfully paired it with my MacBook.  I do not have a USB Keyboard or Mouse and without purchasing additional hardware, do you have any suggestions to work around this problem?
    Thanks, Julian

    Hi Julian,
    Sometime a Mac can't pickup the connection of a bluetooth keyboard or mouse is normal. Whatever your Mac is brand new or not.
    I will do the following if the brand new Mac can't pickup the bluetooth connection, but make sure the bluetooth keyboard and mouse is not yet paired with other computer, that means you have to un-pair the keyboard and mouse from your MacBook before you perform the follow step:
    - Switch off the Mac
    - Switch off the Keyboard and Mouse which not yet paired with other computer, remove its battery, and re-install the battery after 10 seconds
    - Switch on the Keyboard and Mouse first, make sure both devices have a green light flashes (the light flashed at intervals, like a pulse **...**...sorry my poor English), that means the devices is discoverable.
    - Switch on the Mac asap if all the bluetooth keyboard and mouse is ready, and let the Mac pair both device (according the screen instruction)
    If the method still doesn't work, the worst case is: i'm afraid you have to connect wired keyboard and mouse to finish the Setup Assistant, and pair both bluetooth devices by Bluetooth Preferences. Once both bluetooth devices connected, disconnect wired keyboard and mouse.

  • USB External HDD not recognised in OSX 10.5.4

    Hi,
    I am attempting to use an ISOGEAR250 2.5" IDE external HDD on my iMac.
    This deviceis advertised as 'compatible with OS/X', which is in fact only true up until version 10.4.9.
    The device is not detected on any OS/X version with the IOUSBMassStorrageClass.kext or IOUSBfamily.kext kernel extensions of any version of OS/X past 10.4.9.
    The only way to get this device to detect on Leopard is to revert the specific kernel extensions to earlier versions, and use the USB Prober utility. This is quite a dangerous exercise, and can lead to operating system instability.
    I have tried the device on numerous Apple computers, and it only works on the ones with OS/X 10.4.9 or earlier installed. I have also experimented with many different file system formats. This device works fine on Windows machines, including Windows in Bootcamp, and Windows using VMWare or Parallels.
    For your information, the device does turn up in the System Profiler with the following info, but will refuse to mount with kernel extensions past version 10.4.9:
    USB4500 FW1.04:
    Version: 0.001
    Bus Power (mA): 500
    Speed: Up to 480 Mb/sec
    Manufacturer: DATAST0R Technology Corp
    Product ID: 0x4500
    Serial Number: 1966XXXXXXXXXXXX (I added in the X's)
    Vendor ID: 0xed06
    If I plug the HDD in while my iMac is sleeping, it will wake up the iMac.
    I have tried the device on both the iMac's built-in USB ports, as well as with a powered USB hub.
    Numerous other users have had similar of the same problem
    (see: http://discussions.apple.com/thread.jspa?messageID=7835455), and yet Apple has not yet rectified the problem, which is clearly arising from the update to the operating system, and not the device itself.
    Does anyone have a fix for this problem, aside from reverting the kernel extensions and using the USB prober?
    Thanks for your help,
    Cal

  • USB external drive not readable by mac but readable by windows

    Hi, I have a usb external drive (Seagate FreeAgentDesktop Media) which works fine with windows xp but cannot be read by the mac. I reinstalled the mac a couple of days ago because it was being very slow and I had a bunch of junk on it. Anyway, after that, it won't read the external drive. It will give me an error message saying that the disk is not readable by the computer. Sometimes it will give me the message saying that the drive was unmounted improperly by windows and for me to unmount it correctly. When I go back to windows, it's there, then I restart and go back to mac, it'll give me the message that the disk is not readable. I have 2 of these drives and both of them have this issue. I also tried disk warrior but it says that the file system cannot be rebuilt. I tried USB flashdrives and they work. I got all the data off of one of the external drives into the other and I couldn't format or even erase the drive because it says that the permission was denied. However, I could format it and erase it with the installation DVD. But I had the same result no matter what format they were in. I have very important data on these drives and I really need to be able to use them with both operating systems. Thanks a lot!

    Hi Schmerz Meister;
    If DiskWarrior say it can rebuild the disk about your only other alternative it to reformat it.
    This will of course destroy all data on the disk so make sure you have copies of the data elsewhere,
    Allan

  • First time starting up iMac, USB keyboard not recognised

    i have tried to set-up my imac, however the keyboard is not recognised and says that i have to turn on my bluetooth keyboard when i have  a USB keyboard and it will not go on to the next step.

    Hi manocchio1994,
    Thanks for contacting the Apple Support Communities. I understand your keyboard is not recognized when connecting if for the first time and I know how frustrating that can be. There is a fantastic article available for USB keyboard troubleshooting I would recommend.
    None of the keys on my keyboard work
    http://support.apple.com/kb/TS1996
    Troubleshooting your Apple USB Keyboard Step-by-Step
    If your keyboard keys still aren't working after trying the steps in USB Basic Troubleshooting, try these steps, in order, until you've come to a resolution.
    ▪ Unplug all devices from your computer, including your mouse and keyboard, as well as your printer, scanner, cameras, iPod, external hard drives, and hubs. (Warning: Some devices, like iPods, may require you to perform steps before it is safe to unplug them.) If you have a hub, don't forget to unplug it as well.
    ▪ Plug your keyboard and mouse back into your computer firmly and securely. Take special care to make sure that the connector is completely in the port. (USB plugs fit into ports one way only, and won't plug in if you try to plug them in upside-down.)
    ▪ If that still doesn't work, try plugging your keyboard in to the other USB ports. Be sure to try them all. Check to see if the keyboard's Caps Lock light turns on when you press it, and try typing in one of your applications, such as TextEdit.
    ▪ If your keyboard works in one of your USB ports but not all, your computer may need service to resolve an issue with its USB port or ports.
      If your keyboard doesn't work in any of your computer's USB ports, it appears that your keyboard isn't functioning properly and needs to be replaced. You can order this part online. Order a replacement keyboard.
    If needed, I suggest resetting the System Management Controller as well. Those steps can be found in the following section of this article.
    Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve

  • Maxtor USB external drive not displayed anywhere. How do I navigate this?

    The drive is plugged in the USB port, however it does not show up on my MacBook air. It is formatted for PC and I wish to download music files then reformat it to use with my MacBook. Thanks for the help in advance.

    Howdy matthewjh,
    It sounds like you have this USB external HDD that does not appear anywhere on your Mac. Assuming it is formatted as FAT-32 I would use the troubleshooting information for USB devices not working in Yosemite, named:
    OS X Yosemite: If a USB device isn’t working
    If your USB device isn’t working, there are several things you can try to solve the problem
    If a USB device isn’t working properly, make sure you connected it to your computer correctly, plugged it into a power outlet if it has a power cord, and installed any software it needs. 
    Check power and cables: 
    Make sure the USB device is turned on and its cables are properly connected.
    Check for missing software: 
    Make sure you installed the latest software for your device. Visit the manufacturer’s website for any updates.
    If the device is connected to a USB hub: 
    Make sure the device and the hub are the same speed. Connect USB 3.0 SuperSpeed devices to a USB 3.0 SuperSpeed HUB, USB 2.0 Hi-Speed devices to a USB 2.0 Hi-Speed hub, and so on. 
    If the device doesn’t have a power cord and is plugged into another USB device that doesn’t have a power cord: 
    Try plugging the device directly into your computer’s USB port  or into a USB device that does have a power cord. You might need to disconnect and reconnect the other device as well, if it has stopped responding. 
    If you have many devices connected to your Mac: 
    Disconnect all USB devices except the device you’re testing, an Apple keyboard, and an Apple mouse. Make sure that the device is connected directly to the computer, and that any hubs or extension cables are disconnected. If you can use the device now, the problem may be with one of the other USB devices or hubs you had connected to your computer. Try reconnecting them, one by one, to your computer. When you find the device causing the problem, review its documentation for further troubleshooting steps. 
    Verify that the device appears in System Information: 
    Choose Apple menu > About This Mac. In the window that appears, click Overview, then click the System Report button to open System Information. 
    In the window that appears, see if the USB device is listed below Hardware in the Contents list. If the device appears but does not work, review the device’s documentation for further troubleshooting steps. 
    Restart apps: 
    Quit and restart any apps that use the device. 
    Restart your Mac: 
    Choose Apple menu > Restart.
    Thank you for using Apple Support Communities.
    All the very best,
    Sterling

  • USB External HD Not Working

    Lately my computer has been crashing a lot.. different things such as just randomly freezing andnot being able to move the mouse or even click... another thing is freezing and showing a screen with white text and a black background giving different errors in code.. sometimes it also says i need to restart my computer. its also freezing in safari and other applications. i reinstalled everything and its still doing it. now im trying to hook in 1 of my 2 usb external hd's and wired keyboard & mouse and only one of them works. ive tried changing ports and cords and what not, but i think theres something else wrong with my computer. can anyone help?
    PowerBook G4   Mac OS X (10.4.5)  

    Have you run the Apple hardware test? Insert your OS X disk, hold the option key down while rebooting, and choose Apple hardware test. Does it show anything?
    Have you recently made any hardware changes, like adding new memory? When you click on the blue apple and about this mac, does your total memory show correctly? Have you reseated your memory?
    Have you created a new user on your system, through the account prefernce pane, to see if you have the same issues? If you have the same issues, then you know it's a system-wide problem (hardware or software). If you don't have the issues, then you know the cause is related to something specifically associated with your other ID.
    Have you done a safe boot? Reboot your system, holding down the shift key. This does some housekeeping and bypasses loading some startup items. After a successful safe boot, if you reboot normally, do you still have the problems?
    Do you run a program like MacJanitor or OnyX to ensure system maintenance is taking place? I use OnyX, which is available here. Run the cleaning and maintenance tabs.
    The above steps will cover alot of troubleshooting ground. You should also view the kernal panic guide by Dr. Smoke here.
    Let us know what you find out.

  • External USB Hard Drive Not Recognised / Seen

    Hi,
    I have a WP 250 GB External hard drive which was working fine until recently and now is not recognised by my 2007 Intel Macbook. When I plug in the hard drive, a light comes on solidly and it begins whirring. Then, it continues to whirr as if it was going to work, but the light starts flickering.
    It is not visable as an external hard drive in finder. 'View Hard Disk' is switched on under Finder / Preferences. On System Profiler, when I click 'USB' fom the list on the left, the computer displays the circular "thinking about it" spinning thing, and system profiler freezes, and nothing else happens. The same thing happens with disk utility.
    I tried plugging the hard drive into a windows computer, and it worked fine; all the files inside it were visable. It is formatted to my mac and I have successfully used the hard drive many times before. A logical next step would be to try it on another mac but I don't have access to one.
    I have tried to to a PRAM reset, but couldn't do it, even following the instructions on the MAC website (turn off computer, turn on and hold the mac button, ctrl, p, and r simultaneously) it wouldn't do a PRAM reset.
    I am not a computer expert, but I am not completely green either. Why is it that doing the simplest thing on a computer requires a minimum of a 4 year computer science degree or equivalent.... somebody please help me crack this, I am close to smashing the whole thing to pieces with a hammer (which would be satisfying but counterproductive and expensive...)
    Thanks in advance for your replies

    Did you allow Windows to upgrade the formatting on this drive from FAT to NTFS recently? You should be able to check the formatting on the volume from within Windows. It would also be worth trying to repair the drive under Windows if it allows you to.
    Note that NTFS is not readable under OS 10.4.x without special software. NTFS is read-only but not writable under OS 10.5 and later.
    If the volume isn't NTFS, and repairing it doesn't help, you may need to just backup the data and try to reformat it.

  • USB Keyboard not recognised on launch of iMac

    Have just purchased iMac with Maverick OS pre installed.
    Purchase with Apple USB extended keyboard and Apple USB mouse.
    On first day when iMac turned on mouse and keyboard functioned. Then when turning on iMac on day 2 (!!) the launch window displayed message - Bluetooth Keyboard setup / There isnt a keyboard connected. Looking for wireless keyboard..... etc etc.
    The wheel in bottom of window spins for ever.
    Only way to turn off machine is hold down power button.
    No bluetooth keyboard was ever connected to iMac ...
    Have tried connecting the USB KB directly to back of iMac on launch and via USB hub.... neither option works.
    Mouse does functions when connected to laptop (Macbook pro) ...
    So iMac is not working... what to do now? Anyone else face this problem?

    Go to: Apple > System Preferences > Bluetooth and if you do not use any Bluetooth devices, turn Bluetooth Off.
    If you have and use other Bluetooth devices, leave Bluetooth On, click on Advanced... uncheck the Setup Assistant box or boxes and click OK.

  • Keys on external keyboard not working

    Hi folks,
    I recently purchased a USB keyboard (extended numeric) for my MacBook Pro, and all has been good until this morning, when the V and Y keys (both lower and upper case) have stopped working, i.e. when I try typing with them, nothing appears. With the V key, the Edit button flashes, and nothing happens (that I can notice, anyway) when I try the Y key. (Thankfully my macbook keyboard is all okay.)
    I wondered if the keyboard might have shorted, but all other keys are working okay.
    Any thoughts?

    Yes, the built in keyboard works perfectly well, both with the external keyboard connected and disconnected. I'm hoping the external one isn't beyond help... it's such a pain to have to replace!

  • Macbook air stuck in No bootable device, external keyboard not working.

    Hello.
    Yesterday tried to install Windows 7 via Bootcamp. As everyone else got to "No bootable device - insert boot disk and press any key."
    After few seconds I realized that keyboard is not working. Googled it and found out that I need to buy an external keyboard.So I did.
    Guess what,external keyboard is not working too. Tryed with different PC, it worked with them.
    So what now?

    The Formatted test drive did not have Any OS on it. I just thought that since that was how I installed it originally, that it would work.
    I put in SSD straight out of package, connected Firewire drive with SnowLeopard install, and it booted to it and asked me for to install to which drive, I choose SSD and it took off..
    So what your saying is, do the same thing but hang SSD from broken Mini onto working Mini and boot up with same Firewire drive, and have it install OS back onto Broken SSD drive.
    Assuming all of this works correctly, why would plugging it back into broken Mini work? Wont the Broken Mini still be looking for BootCamp to finish what it started? (just seems that way from what I've experienced so far)
