Sony Walkman NWZ-E463 "unknown device".

Sony Walkman NWZ-E463 "one of the USB devices attached to this computer has malfunctioned and windows does not recognize it." It does not appear on my computer, I open Device Manager it shows as an "unknown device", and it does not load. When I use another Walkkman on the computer, it works fine very well. Conflicting drivers because we're a 4 GB model and the other is a 8 GB and require different drivers? I used both successfully in the past, why it suddenly does not work? I tried to uninstall the drivers and nothing seems to work.

  • New Sony Walkman NWZ - M464 MM Player installs (to facilitate file transfer) software taskbar on my laptop. . Were wiped out my media files on PC

    Since last week, after installing the software MediaGo integrated into my new Media Player Digital Sony Walkman NWZ-E464 - which was to facilitate the transfer between the camera and the PC - I've known everything, but a transport seamless music and photos.  Allegedly, the software is designed to simplify the process by using just one application to streamline the effort.  However, my pictures, and my music are in chaos due to this element.

    I lost folders with hundreds of photo files in transfers.  Some are found on the Sony; the other disappeared fronm the laptop.  I have no idea why my Flip videos stills are in past in photos on the device files.   I found MP3 files in some of my document files.  It was last week when I thought that carrying the music from my PC to the Sony.  Now, Windows Media Player will not play CD I insert the optical disc; It does not recognize the artist or the 6 following the statement (I'm connected to the internet at the time).  Tear up or burn?  Out of the question.

    After that the unit stopped and stop in the middle of a transport of pictures, and Windows blinking a Code 43 "Windows does not recognize this legacy", I cleared any activity of this kind.  Occasionally my PC screen open these windows (without the trendy Sony) offer me to download codecs.  I searched for what seemed to be executable files (codecs). It turns out that this one was compared to the Sony - exe SRL, I think.  And the other was a JPG file, which could explain why my JPEG photos. have been bailing out.  Anyway, I can't help but wonder why Sony, if he had not the conversion factor to the bottom for the transport of my Windows 7 OS, it does not tell me that this codec SRL? are relevant to a success - if they were still (to 60, it is difficult to keep in touch with tech pace today, and there is a good probability that I don't even know what I'm talking about).

    I'm reluctant to run again - even if fixable - MediaGo after this experience.  I want to simply move the computer to the MP3 stuff.  So my question, I guess, if I uninstall the software from the laptop how down it the Sony?  And will she try to reinstall MediaGo on the PC?  Also it is not late to send it back to Amazon, but where he was baptized already, I doubt I have would be allowed to return.  Is it possible to clear the taskbar of the device?  Then I could manage it as an «old fashioned MP3 player»

    Please forgive me to babble on... and on... I think that I work only on what could have happened while typing on this subject and arrive at the relevant issues to raise awareness in the light of the situation.  I'd certainly appreciate suggestions raised apart from my point of view of neophyte.  Thanks obstinate by this stroke of mouth and all your relevant ideas and advice will be much appreciated.

    Windows 7 has stopped recognizing my Sony Walkman NWZ - E438F Media Player since the last update. Do you have a system restore, and it did not help. Restored the walkman to the factory settings, and that did not help either.

    The walkman works fine on another computer. I tried all my usb ports - and ports all work with other devices, but do not recognize that there is an external device connected, when I try the walkman. I get power from the usb connection, however.

    Which driver? You plug the USB cable and it shows up as an external drive - computer should recognize pretty good right now.

You can even drag and drop MP3 files into the music using Windows Explorer folder.
