U430 powered USB 2.0 port charges devices but does not recognizze

I just got a U430.  I noticed that any devices plugged into the powered USB port on the right side of the computer will charge, but the computer does not recognize them.  I tried disabling/enabling all the USB hubs in the Device Manager, unselected the option to have Windows turn them off to save power, and did the same in the BIOS.  I can't seem to update the drivers as it says they are all the most recent ones.  Any thoughts?  This seems like a recurrent problem with other Lenovo products, and I don't see a real solution in most of the threads.  The OP just stops replying.  
Thanks!

hi turtl631,
Welcome to the Forums.
Just to verify, what are the devices (brand/model) that you've tried so far? Also, is the machine running Windows 8 / 8.1?
If a flashdrive won't work and you're running Windows 8.1, kindly check this thread for a possible resolution. 
Let me know how it goes.
Regards

  • TS3253 Is my original iPad compatible with iHome DM12 wireless speaker.  I am having trouble with pairing.  The iPad sees the device but does not connect

    Is my original iPad compatible with iHome iDM12 wireless speakers?  I am having trouble pairing.  iPad sees device but does not connect.

    It should be it the iHome supports the bluetooth profiles that the iPod supports. See:
    iOS: Supported Bluetooth profiles
    Try resetting the iHome if it was previusly paired to another device.

    I just purchased a new Linksys E2500 router.  It will connect to all my other devices, but does not recognize the password when sent from the PowerBook G4.  When I try it responds that the password is invalid.  I have connected my MacBook Pro, iPad and iPod Touch with the same password.

  • Elitebook works on battery and charges it - but does not start with it (only starting on AC)

    Hey,
    my 8460P only starts up when connected to AC power. Even with a fully charged battery it does not boot, i also have tested this with a replacement battery - but batteries are working on another Probook.
    Strange: If I unplug the AC directly after powering ON, the 8460p continues running on battery.
    What exactly happens:
    I have fully charged battery and no AC connected. I press the power button, the CPU fan makes noise (full throttle), LEDs are glowing: Wireless, Power and HDD. The DVD drive is initializing... and then after 3 seconds device shuts down - BUT the power LED keeps glowing.
    If I then press the Power button once again, nothing happens.
    But when I connect the AC back, the SCROLL LED glows for about 3-4 seconds and then turns off.
    What I did already: The well-known hard reset (disconnect everything, hitting power 30seconds): no success.
    Latest BIOS is installed. Factory defaults loaded... nothing. Played around with different BIOS settings (everything which sounds for "power" or "AC" tried...) nothing.
    This is not OS related - so updating any drivers or software does not make sense. 
    Further remarks:
    Also from the sleep modes (hibernate or S3) it will not wake up from battery... again only when connected to AC!
    Any solution/idea? please support. 
    Thanks a lot!
    regards,
    G

    Hi Rebeccaegan,
    Welcome to the Support Communities!
    Try the specific steps below for your iPhone first:
    iOS: Device not recognized in iTunes for Windows
    http://support.apple.com/kb/TS1538
    If the issue is not resolved, you may need to uninstall iTunes and all of it's components, and reinstall the latest version as explained in this article:

  • When I connect my iphone 5 to charge, repeated again and again the charge sound, but does not turn! HELP!!

    help with iphone, you may not start and repeat the sound over and over again that the screen is broken?

    Hello obrunaga,
    Thank you for providing the details of the issue you are experiencing with your iPhone.
    I recommend following steps 2-6 below for an issue like the one you described:
    If a single application is not responding or stops responding when it opens, you can force it to close.
    If the device is unresponsive or if certain controls aren't working as expected, restart your device.
    If the device remains unresponsive or does not turn on (or power on),reset your device.
    If there is no video or if the screen remains black, verify that the device has enough charge to turn on:
    If you are using an iPad, ensure that it's connected to the USB Power Adapter supplied with the device.
    Let charge for at least twenty minutes, then see if it starts normally.
    If there is no image on the screen, press the Sleep/Wake button to attempt to wake the device.
    If the screen displays a red battery icon, continue charging the device until the battery is fully charged.
    If the above steps do not resolve the issue, or the if the screen remains black or shows a persistent Apple logo, try restoring with iTunes:
    Connect the device to your computer and open iTunes.
    If the device appears in iTunes, select and click Restore on the Summary pane. Learn more about restoring iOS software.
    If the device doesn't appear in iTunes, try to force the device into recovery mode, and then restore it.
    If the above steps do not resolve the issue, contact Apple.
    You can find the full article here:
    iOS: Not responding or does not turn on
    http://support.apple.com/kb/TS3281
    If you get to step 5, I recommend backing up your iPhone before performing the restore:

  • Windows Phone 8.1 Universal: VS 2013 deploys app to device but does not delete data file in roamingfolder and roaming is not activated.

    I am using VS 2013 to develop a Windows Phone 8.1 Universal app.  When I deploy to the device (my phone), the old data file that I had stored in the roamingfolder previously continues to be used.  I have uninstalled the app after being deployed,
    I put code in the app to delete the files individually from the roamingfolder and used ClearAsync(). That worked until I deployed the app again and then the old files came back.  I have not associated these apps with the store yet so roaming should
    not be working. The desktop app does not have this problem, when I uninstall it the files are deleted.
    In the phone app properties debug tab, I have the Uninstall and the reinstall my package checked for all configurations.  I have looked everywhere I can think of for these old files: laptop c:, phone tempfolder, localfolder, etc. thinking VS is reinstalling
    them from somewhere when deploying the app but I cannot find them.  If I change the phone app to use the localfolder, the old files are not used.
    Is this just the way it is if I use the roamingfolder or is there a way to delete these old files?
    Any help would be greatly appreciated.  Thanks.

    Hi MV12,
    >>When I deploy to the device (my phone), the old data file that I had stored in the roamingfolder previously continues to be used
    Yes, it is designed to work like that, please refer to this document for details:
    #Accessing app data with the Windows Runtime (Windows Runtime apps)
    https://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh464917.aspx#roaming_app_data
    Roaming data for an app is available in the cloud as long as it is accessed by the user from some device within the required time interval.
    If the user does not run an app for longer than this time interval, its roaming data is removed from the cloud.
    If a user uninstalls an app, its roaming data isn't automatically removed from the cloud, it's preserved. If the user reinstalls the app within the time interval, the roaming data is synchronized from the cloud. The current policy specifies
    that this time interval is 30 days. Location is available via the roamingFolder property.
    >>Is this just the way it is if I use the roamingfolder or is there a way to delete these old files?
    No, you will have to wait.

  • HT1320 My Laptop doesn't recognise my iPod nano. When I connect to laptop it charges it but does not recognise it as a storage device or iPod

    I have tried all of the online help topics and still cannot get it to work. It use to be fine on my old Laptop, but just will not connect to my new laptop.

    Try:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
    - See if another computer sees the iPod in iTunes
    - Restore from backup. See:                                 
    iOS: How to back up           
    - Restore to factory settings/new iOS device.
    If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

  • Anker Powered USB Hub (7 port, usb 3.0) often won't light up (function) after waking Mavericks from sleep

    My iMac is  27" (mid-2010) with 8 GB RAM. My only problem is that my new Anker Powered USB Hub (7 port, USB 3.0) often does not wake when computer does. In other words, the power lights remain off following waking the computer from sleep and I must unplug and replug the HUB. I called Anker and they told me that Mavericks has a new "energy saving power mode" that may turn off power to a USB hub. This is most annoying and I hope that Apple can update Mavericks power management to fix this USB issue. Has anyone else experienced this problem? I've seen similar posts from D-Link USB hub owners. Perhaps if this "question" has a response trail, Apple will see it and create a fix.

    Hopefully, Apple will monitor this issue and correct the USB power management issue. We'll see what happens with Yosemite.

    I have a honda civic with USB port which allows play back of my old iPhone 4 and 4s.  With the new iPhone 5 the radio shows the phone is conected but does not show any music content.  Any Suggestions?

    You should be syncing your contacts with an app on your computer or cloud service (iCloud, Gmail, Yahoo, etc), and not relying on a backup.  If you haven't been doing this, start now and then restore your old backup.  You will then be able to sync the new contacts back into the phone.  However, you will lose all messages, etc newer thant the backup.
