Aluminum Keyboard Sometimes Not Recognized By USB Port

I have an Aluminum wired keyboard that occasionally isn't detected by my Macbook in both Windows XP (Boot Camp) and Leopard. This is an exchanged one because the first one also behaved this way. I'm not using the extension cable. I have a USB wireless mouse plugged into one of the keyboard's USB ports and a flash drive. When the keyboard isn't detected, the mouse doesn't work (no lights on the receiver, can't connect), but the flash drive gets recognized. I've also had the keyboard not be detected without the flash drive so I know that it isn't the issue.
When it isn't detected I have to disconnect and reconnect the keyboard multiple times until it randomly starts working. Once it works, it doesn't stop working, though after going to sleep it occasionally disconnects itself on startup. All the function keys work properly and there's no updates available...is there anything I can do about this?

I've seen the very same problem. In my case I have a wired Mighty Mouse attached to one of the USB ports on the aluminum keyboard. Every time I plug it in -- not recognized first time. Second time -- success. Highly annoying.
Unfortunately I don't have a solution for the problem.

  • Ipod Touch not recognized by USB port on my new radio! PLEASE help?!?!?

    Ok, so I just bought a new radio for my car so I can listen to my ipod touch 2nd gen (with the latest 3.0 software) through my speakers. Ok, that's all great, but the problem is that when I connect my ipod touch through the USB port on my new radio, it reads "device error"...
    My radio is an Alpine CDE-102. It does have an AUX input, and I can easily get a cable to fix this problem... but I'm wondering why my ipod touch doesn't show up through the USB?!?! And I don't know how AUX input sounds compared to USB input (probably less quality than the USB...)
    So, can you help me? I've also connected my ipod touch to my xbox 360 and it shows up as a camera - can't play music... all part of the same problem I guess...
    This is a SERIOUSLY annoying problem especially since I just dropped some cash on the new radio which might not even WORK!!! AHHHHH! A problem with the USB cable? Problem with the Ipod? Problem with the stereo? I'm not quite sure what to think...

    That is the ONLY cable that will work with that radio:
    http://www.alpine-usa.com/US-en/products/product.php?model=CDE-102&view=Specs
    From reading the manual for your iPod I'm pretty certain the connector is on the rear of your unit.
    You can connect an Auxiliary cable to the headphone out on your Touch to the AUX in on the radio but you will have to control everything with the iPod and it will not charge.
    The cable is $30, why don't you ask how much they would charge you to install it?

  • My USB Apple Aluminum Keyboard is not responding during Bootcamp Install!

    I am going crazy, I have had the worst experience with this Bootcamp install which is supposed to be so easy, resulting in Apple replacing my MAC pro, and I still can't get it to work on the new machine.
    My first problem was using a Windows XP Pro disk, which resulted in my continually getting a black screen saying "no bootable device, press any key to restart." I ran into this problem because I overlooked the instructions to use a USB keyboard and mouse, I was using the wireless. This process resulted in Apple replaceing my MAC Pro because some how my start-up files dissappered and the MAC geniuses couldn't even reformat my drive.
    After recieving the new MAC Pro, I tried to run the Boot Camp install, using the same Windows XP Pro Disk, but now with a wired USB Apple Aluminum Keyboard and USB might mouse. I was still running into the same problem, after windows finished the Install and restarted a black screen would appear "no bootable device..." After searching many forums I found that for some reason Windows XP Professional disk skip the step where you would format the drive you partioned for Windows. I found in a forum a way to address this problem by going in DOS and entering commands to tell Windows to format the drive. I was not comfortable doing this, so I thought I would take an easyier route and get a Windows XP Home edition.
    All windows versions I used were OEM, but they were all full installs (fancy hologram CD) w/Service Pack to and certificates of authenticity**
    I thought great now everything should go smoothly, I have Windows XP Home Edition w/SP2, I have a USB wired apple aluminum keyboard, and I have a USB wired might mouse. This has not been the case.
    After I complete the Bootcamp process on my Leopard operating system and Windows XP completes loading all the file prior to begin the Install, the Windows XP Installation asks to press "Enter" to begin Install. This is the point now I can't get past, because I get no response from my keyboard. I tried every USB port on my CPU and still no response when I reach this step in the Windows Installation. I am becoming very disgruntle with Apple because the AppleCare, which I pay for, and the MAC genius will not help me with this problem because it is during the Windows Install. Please help before I flip out.

    That worked after using a generic DELL PC keyboard no extra keys. Apple hustled me into buying a wired keyboard, because I had only ordered the wireless keyboard.
    Thanks

    the keyboard sometimes not appearing until restarting, why?

    Do you use a BlueTooth keyboard? If you do and that keyboard is too close the the iPad the keyboard may not pop up. Turn off the keyboard or turn off Bluetooth if that is the case.

  • 2nd generation ipod shuffle not recognized by usb 3.0 port, 2nd generation ipod shuffle not recognized by usb 3.0 port

    Hi,
    My 2nd generation ipod shuffle will not connect to any usb 3.0 port.  I've tried on to computers -- one Windows XP and the other Windows 7.  Any ideas?

    Hi
    I had the same issue with my Late 2009 Mac mini running Mavericks and iTunes 12. When I connected my 2nd generation iPod shuffle it would blink amber once then do nothing. This seems to be a common problem with the iPod shuffle and newer versions of Mac OS X (10.6 and up) and iTunes albeit with somewhat varying symptoms but the same overall problem syncing the iPod with iTunes.
    The predominant go-to solution is to give the iPod more power by either connecting the iPod directly to a USB port on the Mac or by disconnecting all other USB devices. On paper this makes sense.
    What worked for me, however, was the opposite. After trying to solve this problem for hours (weeks, months), I had success ONLY after adding a low-powered 4-port USB hub to the chain between the iPod and the Mac. I suspect this had the effect of throttling the power supplied to the iPod from the Mac. I was able to perform a restore on the iPod then sync my music over.
    I can't tell you much about the USB hub except that it is running at USB 1.1 speeds (12 Mb/sec). In theory a USB 1.1 extension cable should also do the trick. You might even be able to use the USB hub in old wired Apple USB keyboard. I will attach a photo of the hub I used to this post for greater clarity.
    I really hope this helps.

  • Keyboard not recognized in USB hub after 10.6.3 update

    After updating to 10.6.3 (using combo updater) the keys on my Apple extended keyboard that shipped with my 24" iMac (2008) no longer work when the keyboard is connected through my Belkin powered USB hub. But oddly enough, the wireless mouse that is connected to the keyboard does work. So the keyboard is recognized and connected properly, but the keys don't work! It's definitely a software thing.
    I don't have enough free USB ports on the back of my iMac to dedicate to my keyboard. Any help appreciated. Thanks!

    I have the same problem. I found I can unplug the keyboard and when replugged, everything works OK.
    I just upgraded to OS V10.6.4 and still must unplug and replug the keyboard in order to type.
    WHY?

  • Press any key... help! the usb keyboard is not recognized and I cannot reboot

    Hi,
    I really hope that one of you can help me. I had used boot camp once on my MacBook Pro so, I did not think to plug a USB keyboard on my son's iMac before starting the installation process. As a result, when I am asked to press any key, I am stuck. Obsviously I could not reboot so I unplugged the iMac hoping that it would come back to OS and give me a chance to have the USB keyboard installed and recognized before going back to the installation. Unfortunately, rebooted and went directly to where I was at.
    Thank you for your help

    I would restore the iPod to factory defaults/new iPod on your computer and start over. It appears the iPod is associated with another account.  Any media that came with the iPod does not belong to you and di not transfer with the iPod hardware.

  • Intel iMac with new usb aluminum keyboard will not recognize boot options

    I have a first gen Intel iMac core duo 20". After I replaced the old usb keyboard with the new aluminum usb keyboard, I can no longer boot into single-user mode, select to boot from a different volume (including boot camp), boot from a CD, or boot into target mode. All of the boot key options no longer work. These options do work with an older Apple keyboard. I have all the latest updates including the latest firmware and keyboard drivers. Help Apple, I really need to boot into these different options and with the new keyboard, I can't. I have read several other accounts of this on other sites.

    I have an early 2006 intel iMac and am having the same problem with the new keyboard. Called AppleCare, who sent me to the local Apple Store after trying several minutes in vain to cure the problem.
    One of the Genius's at the Apple Store pulled up Article 306893, Apple Keyboard (2007): Cannot boot to Startup Manager. This is a document that's apparently not available to the public, as I have the printed copy, but have been unable to pull it up in my searches.
    The issue is some intel-based iMacs and Mac mini computers shipped prior to 2007 may not boot to the Startup Manager when holding down the Option key on the aluminum keyboard (2007).
    My iMac is listed among the products affected.
    The solution they offer is to follow these steps:
    1. While starting the computer, point the Apple remote at the computer and hold down the Menu button. The computer should boot into the Startup manager.
    2. Use the Fast Forward and Rewind buttons to select the desired boot volume.
    3. Once the desired boot volume is selected, press the Play / Pause button to continue booting.
    Hope this helps. It works for my system. Still doesn't solve the keyboard issue but offers an acceptable workaround.

  • IPOD not recognized via USB - A lot of trouble shooting already done.

    I got a new 80GB iPOD to replace the 4th gen 40GB that just died (HDD issue). I cannot get the computer to recognize it via USB. I had the same problem with my 40GB via USB, however it would usually work via firewire. This new one will not let me use firewire, so I am forced to try to resolve the issue. I know this has come up before on here and I spent about 3 hours last night going through old 'USB Device Not Recognized' posts, but could never find anything similar. This is where I stand. Any help would REALLY be appreciated, because I am pulling my hair out over this.
    All previous Itunes have been deleted and Itunes 7 has been installed. This is on WIndows XP Pro.
    1. I know it is not a defective IPOD or USB cable because I brought them to work (a non Itunes machine) and plugged it up. IPOD was immediately recognized as IPOD /USB Mass Storage Device.
    2. I know it is not the USB port at home because I plugged other devices (Klipsch Promedia speakers / Mouse / Keyboard) into the same port and they worked. Incidentally, this is a front USB port, however, I get the same result if I use a rear port.
    3. It is not recognized in Itunes or in 'My Computer'. Only recognized as 'unknown device' in Device manager.
    When I plug it up at home, it goes through all the 'new hardware detected' crap and then 'you new hardware is ready to use', but then after about 3 seconds, I get the 'USB Device Not Recognized....USB device has malfunctioned ....'. message. If I go to device manager and uninstall it and then retry. I get the same thing. Even f I reboot between tries.
    So, I have pretty much ruled out a hardware problem. I think I read on here somewhere (or a link from Apple) that there was a Microsoft hotfix issued for this issue last year sometime (I think it was a SP2 compatability issue), however, I cannot find the fix. The link I had talks about the hotfix, but there is no file. Also, since the issue first appeared last year, I would think it has been resolved in one of the updates since then.
    PLEASE help me out if you can. Thanks!

    Here is what worked for me:
      My usb hub, being usb2, was too fast. I moved the wire to a usb port directory on my pc. That is a usb1 port which is slow enough to run your snyc.

  • IPod not recognized on USB hub

    What would cause an iPod Nano to charge while connected to a 1.1 USB hub, but not be recognized by Windows or iTunes?
    My brother connected his Nano to a USB keyboard port, and has lost it's charge. I've been able to get it to charge on my 1.1 USB hub, but not a 2.0 USB connection. The iPod is also not noticed by Windows or iPodServices.
    I put the iPod into Disk Mode and tried all five 2.0 USB ports on my motherboard. It will only charge on the USB hub, but again, won't be recognized by iPodServices.
    Intel Pentium D 320   Windows XP Pro  

    I have the exact same issue. Did you get it resolved. I have a replacement Nano and I think that is messing it up. I was going to send it back to Apple, but they wanted to charge me another $40.00. That would be now $80.00 to repair this piece of crap. So I am asking you if you got resolution.

  • Gen 1 iPod Touch sometimes not recognized by iTunes (error code 0xE80000024)

    Almost every time I connect my 1st generation iPod Touch to my computer via USB, iTunes (version 10.3.1.55) does not recognize and sync the iPod. Most recently, iTunes gave a message saying that the iPod could not be connected due to an unknown error 0xE80000024.
    Without closing iTunes, I changed USB ports, and iTunes recognized the iPod Touch. (I also have the 4th generation iPod shuffle, and I have never had a problem with iTunes sync.
