USB drives aren't recognized in Windows after Yosemite update.

On my Windows partition, my flash drives aren't recognized anymore. I've tried installing the Windows Support Software. That doesn't seem to do it.

1. Your hardware seems to be functional since OSX can see USBs.
2. Do you have iTunes installed on the Windows side?
3. Can you remove all Apple software and just install the Bootcamp drivers, nothing else and test?
4. This is what I see on my Yosemite DP6 (not GA version) and have a USB2 plugged in which is detected.

  • IPod not recognized by windows after iTunes update

    After my iTunes 6.0 update, my computer (running on Windows XP) suddenly won't recognize my iPod. It says "Does not recognize USB device," and "no driver found". When I connect my iPod to my laptop (which still has iTunes 4.0 installed) it is recognized fine. What should I do? There are some songs on my PC that I do not have on my iPod, and I don't want to lose them by completely uninstalling iTunes. Help!

    Oddest thing happened...I have actually redownloaded iTunes and clicked repair before, and it didn't work. But I just did it again and suddenly my computer recognized the iPod again. It did give me some kind of error talking about how the playlist count was corrupted, but that doesn't bother me very much since I can connect and update again.

    I have the same problem when I updated to OS X 10.10 I lost both my USB ports as far as they will not recognize anything that I plug into them.  The power part of the USB seams to work since it will recharge my Striiv Touch but nothing shows up when you connect anything to the ports.
    I have tried a number of things from rebooting, trying other usb devices that work on other systems with no problems but will not work on my Macbook Pro.
    Any Help out there?

  • My MacBook Pro's internal SuperDrive has stopped recognizing CDs/DVDs after Yosemite install

    After upgrading to Yosemite, my MacBook Pro's (early 2011) internal SuperDrive has stopped recognizing CDs/DVDs after Yosemite install. It takes them in and will eject them with the keyboard button, but they will not mount. Disk Utility shows the SuperDrive and shows the inserted media, but will not mount the disk. That button is grayed out. Please help! I still have training libraries and music I access on such media. Thx!

    UPDATE: I discovered some forum posts about a similar issue with Mavericks that recommended re-installing the system to fix the problem. I realized that I rarely restart my computer unless there's an update that requires it, and decided before undertaking a full re-install of Yosemite to simply restart my computer again. THIS WORKED! The SuperDrive is now mounting CDs and DVDs. Not sure what the issue was, but if anyone else has this issue I hope this will save you hours of frustration.

  • Lacie Rugged external drive will not show up after Yosemite update.

  • Macbook pro - iPhoto keep prompting to update after Yosemite update. Error message when trying to update -This update is not available for this Apple ID either because it was bought by a different user or the item was cancelled

    macbook pro - iPhoto keep prompting to update after Yosemite update. Error message when trying to update -This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled. 

    I only have 1 apple ID and the same was used to set up this early 2011 macbook pro and iPhoto app. I don't want to loose out on any photos. I tried logging out of app store and back in but no luck. PLEEAASEE HELPP!!!
    This problem has been reported by quite a few forum members, who skipped the update to iPhoto 9.5.1 while running Mavericks. In that case try to purchase iPhoto again instead of updating.
    After making your backup try the following:
    Uninstall iPhoto by deleting it from the applications folder, but do not empty the Trash.
    Launch the App Store, click the "Store" menu, and sign in with your AppleID.
    Open the main page of the App Store and search for iPhoto.
    If iPhoto is listed as "Free", click the "Free" button to buy it with your current AppleID.
    If it is not showing as free, there is no help but contacting the App Store Support, as Niel pointed out: http://www.apple.com/support/mac/app-store/contact/

  • My early 2008 Macbook Pro is suffering from black screen after Yosemite update

    My early 2008 Macbook Pro is suffering from black screen after Yosemite update. It ran beta 5 great but failed on restart after beta 6 install. There is no cursor but I can hear the HDD spooling up. I have tried booting in safe mode, PRAM reset and SMC reset but nothing works. After the first 5 days of every now and then trying to start it, it started fine. I used the machine all day with no problems, it had rolled back the install and was back on beta 5. I decided to try the update again, the same thing happened and it has stayed black for over a week now. It wont work with a monitor either. Help!

    Hello Adam,
    I would try instead of installing the beta software, to install the official build of OS X Yosemite from the Mac App Store to see if that gets you passed the no video issue when updating the beta software.

    The program is completely unusable and crashed after update.
    Computer is less than 1 month old and can't run a basic mail program
    I REALLY HOPE APPLE FIXES THIS BUG ASAP    
    Without fix I will return the computer

    True,
    I also have AppleCare, but unfortunately, after calling them they can't determine what is creating the problem either.
    Other forums have shown other troubleshooting steps which didn't solve my problem, but may help others:

  • After yosemite update I'm unable to type in word

    After Yosemite update I am now unable to type in any of my word documents. Any suggestions?

    Sorry for hijacking your post -
    I have had an issue with my Lumia 820 too after installing the Amber update.
    The phone once updated displayed " restarting " and from that point on has failed to go beyond the screen that displays the Nokia logo.
    Spoken to Customer care guys and tried hard resetting the device but to no avail.
    Unfortunately for me i haven't made a back up of the data i have on the phone and I have extremely important business contacts and other relevant info that I can't afford to lose, hope I am provided with a solution. 

  • MSI Z87-GD65 USB Razer Megalodon not recognized by windows!?

    Hi guys, I recently just upgraded my PC and everything is okay except my USB Headphones are not recognized on this system oO I had to reinstall windows to get the motherboard to be compatible with my setup and after updating windows and looking up the problem, I haven't found an answer.
    The Headphones work 100% sure because they worked on my old mobo and my laptop that is right next to me.
    Says its an unknown device and has a ? next to it. Also these headphones use the Windows USB Generic Audio Driver but for some reason its not working.
    Any help would be appreciated alot

    Try the latest Bios: >>Beta BIOSes<<
    I will check for a newer version as well right now.
    Edit: .141 is the latest.
    Might want to check for a firmware update for the usb device as well.
    Edit#2: Install the ram properly and see if that changes anything. Locking this topic as it is a duplicate.

  • My external USB drive is not recognized by Win XP

    Hi!
    I have an external USB drive that is HTF+ formatted. It is not recognized by Windows XP. If I start the windows disk manager it gives me the option to initialize the drive. Do I dare to do this? Will it not erase the information on the drive?
    Thanks for any help!

    Hi Anders and welcome to Discussions,
    I have an external USB drive that is HTF+ formatted. It is not recognized by Windows XP. If I start the windows disk manager it gives me the option to initialize the drive. Do I dare to do this? Will it not erase the information on the drive?
    Yes it will !!
    Although with the BootCamp 3.0 Drivers (from the OSX Snow Leopard DVD) and the 3.1 Driver update (downloadable) Apple has introduced read-access to HFS+ partitions from Windows this feature seems to have some serious problems for some people.
    Personally I see this feature as "experimental" at the moment.
    XP itself knows nothing and therefor can not use/see HFS+ partitions and GPT (GUID partition table) harddisks.
    You might wanna have a look (or buy) at MacDrive http://www.mediafour.com/products/macdrive/ which right now is the better solution.
    Thanks for any help!

    Hope it helps

  • USB drive access issues when using Windows Backup Win7Pro

    I've run into a similar issue. I'm using an RD1000 USB drive which uses hard drives as removable media.  There's an alert which states "Windows backup  needs a CD/DVD or USB Drive to continue."  It then states I
    can continue the backup on the existing media or insert blank media.  By simply selecting Continue the backup will proceed but this interrupts the backup every night so the backup won't automatically run until that challenge is responded too.  I checked
    permissions and reloaded the MS windows driver for the drive.  I tried exFat and NTSF formats. Not sure how to force it to automatically proceed.  The backup is only a tenth of the size of the total available drive space. Any
    ideas?

  • Satellite A300 - Cd/Dvd drive is not recognized by Windows

    My cd/dvd drive has ceased to be recognized by windows (7). I'm not sure what has caused this because it was previously working and allowed me to install office 2010.
    There appear to be no restore points shown around the time when it was working.

    Hi Robert Crockford,
    In your case I would try deleting the upper and lower filters in registry for CD/DVD drive. This is described on official Microosft website how to do this, so just read the knowledge base article and follow the instructions:
