  Step 1: Please do all the same underneath if you did some before as is often total
  a process that solves the problem.

  Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
  Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
  RESTART this will refresh the default driver stack. Even if the reader does not appear to continue

  Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
  ends. Remove and replace, do not just tight. For laptops, you can often clean power and

  Some DVD players do not use the Windows default drivers so check with the manufacturer of system and

  Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD

• ADE does not recognize the Samsung Galaxy Tab 10.1

  I have Adobe Digital Editions on my computer and have been able to load books from my library on my corner and the nookcolor.  I recently bought the Samsung Galaxy Tab 10.1 and attempted to load a book that I just got from the library on ADE but ADE does not recognize the Galaxy Tab as a device.  It does not at all appear in the library.  I checked the files tab as recommended by another post on this site.  The Adobe Digital Editions file is not on the tab.

  I would have given you a little more in detail.  Sorry - who knows?

  I do not have a Galaxy, but I 'assume' that he has some installation instructions

  that came with it, and one of those is to go online to Samsung and register

  the device with them.  Implementation of applications will be a part of this process.

  The ebook app connects you to the Google Bookstore, where you'll probably

  must create an account with a user ID and password.  A small file will be

  put it on the shelf with this information, which ADE will use in interface

  with your tablet.

  I do not have a Galaxy, but when I went through this process with SONY, to

  one time they asked me if I wanted SONY to handle epub files and I

  said no, because I had to use ADE.  You may be faced with the same

  with Google - or not.  I think that the reason why they asked, was that they wanted

  set up an exclusive link with my ereader, which would have kept me

  their ebookstore for all my downloads.

  I hope this helps!

• Portege Z930-118 does not recognize the external USB CD/DVD drive

  My new Z930-118, with windows 7 64 bit home, does not recognize the external CD/DVD drive when I plug it into the USB port.

  The CD/DVD device does not even appear at all in Device Manager.

  The reader is a SE-S084 Samsun and works well on another laptop.

  I already checked for the "upper_filter", "lower_filter" with the regedit, but entries are not there, so no help.

  Hello
  I m not very well how to help you.

  I found some information about this WEIRD disc and it seems that he didn't need an external power supply. Its USB bus powered so I guess around 500mA power since it is the default value provided by a USB 2.0 port.

  I don t think that there is a problem of missing software. It is a plug n play device so you need to connect it to the USB port and the system should automatically recognise.

  From my point of view of the few you try to connect the external USB ODD two ports to aid a * Y * Cableusb.
  I think the reader needs more power provided by a single USB port.

• Windows 7 64 bit does not recognize the USB external drive HARD Stor E art 3.5 "

  I buy the art external disk HARD Stor E 3.5 "and spend a few days in windows does not recognize the HARD drive. Try to connect the drive to other USB 2 ports and nothing happens. Use a USB to see if has been a problem with the USB ports, but all 3 are OK. Try it on the laptop Asus and windows 7 recognizes the HARD disk. I formatted the drive in NTFS FS. In managing records do not show the external HARD disk. What can I do to fix this?

  My laptop is a Qosmio F60

  This is a really silly situation. It can be recognized by other laptops but not your Qosmio.
  According to the description of your HARD drive when connected simply doesn t exist for your Qosmio laptop.

  Some other HDD is recognized correctly?
  What you can try is to reinstall the chipset driver, restart the laptop and test it again.

  Since when you have this problem? Some installed updates of the last days?

• DreamColor LP2480zx does not recognize the USB for calibration

  Hello

  I have a DreamColor LP2480zx, which does not recognize the USB connection to the computer during calibration.  I have my eye HP connected through this monitor, so I know the connection and the cable is good and mouse, keyboard.  My setup is like this:

  Reference Dell 690 running 64 bit + Windows XP

  DreamColor LP2480zx

  Apple Cinema Display 23 "

  I bought the DreamColor used, and in all other respects, it seems to work very well.  The original owner didn't have it calibrated within a certain time, but said that having had no problem with the previous calibration.  I installed the last APS (version 2.0) and updated to the latest firmware.  These updates produces no change in recognition USB problem.

  The interesting thing is, I was able to calibrate the Apple Cinema Display, using the same configuration of connection (mouse, keyboard, and HP eye connected to the computer via the LP2480zx) APS was able to see the USB connection and this very well calibrated monitor.

  I had trouble with this problem for a few days.  I've looked around quite a bit online and found a few others who have this same problem, but I did not yet find someone who can point out a solution.  If anyone has had this same problem, or has heard of results that correct it, please let me know, because it's very frustrating.

  Thanks for any help

  Clay

  An update to my previous post, I realized a work around for this problem.

  Apparently, this problem has to do with the Dreamcolor screen and/or software APS do not like working with 64 bit systems.  I'm not saying that it is always the case, but I saw the other posts on this problem on 64-bit systems, and I spoke with two other people personally who told me that they also had the same problem, try to calibrate its Dreamcolor monitor when it was attached to a 64-bit system.  HP does not seem to be concerned about this problem, because they do not even recognize its existence, but since I'm far from being the first to report this problem, he's obviously not a one-time problem.

  My solution was this: I had connect the monitor to a regular running XP 32 bit system.  After I did, I could re - calibrate the monitor without the problem of USB connection.  This isn't a very good solution because not everyone has access to several machines, running different operating systems.  But it's a work around, and it worked for me.

  Hope this helps other people who have this same problem with their Dreamcolor monitors hooked to their 64-bit systems.

  Clay

  PS- I posted this as resolved, only because I was able to calibrate my monitor.  It's not really solved the problem, but it gets the monitor working again.  Maybe HP will address this problem in the future, but I'm not holding my breath.

• Satellite A200-1AE does not recognize the USB 2.0 flash drive

  I have a problem because my satellite A200-1AE with Microsoft Vista does not recognize the USB 2.0 flash drive. He asks me a program/software!
  The same USB works without problem on other computers with vista!

  Someone knows what to do?

  Hello

  First of all, you must disconnect all USB devices and must remove the USB ports and controllers in the Device Manager.
  After this procedure, you must restart the laptop. After a new restart the Vista operating system should recognize the USB ports and should reinstall USB drivers again.

  Then you must update the Vista to the State! All fixes and patches must be installed. Please note that you will have to visit the MS Update site for all patches

  Notes; MS has released a beta of Vista SP1. I installed it on my laptop and it has solved several problems.

• Aspire One d255 does not recognize the usb connected external ssd drive

  I want to replace the original HDD 160 GB with a 120 GB Samsung ssd 750 evo but bios and win 10 does not recognize the ssd drive as an external drive connected via a usb connection, so I couldn't create an image of my internal hard drive.  Is there a way to clone my hard drive SSD, so I can exchange the disc later?  I need to update the bios, install a missing driver, etc. ?

  I used two different connections: one is a 2.5 "SATA case disc that I used with a disk 2.5" HARD and works very well with the HARD drive and the other is SATA/IDE connector combination with cables for SATA and power and none of these works.  I read in another forum during my research that the Aspire One d255 doesn't recognize any external SSD connected through a USB either.  Since my netbook has no data, and I had just a pure 10 Windows installed on his drive HARD internal, I removed the 160 GB HARD drive and replaced by a 120 GB SSD and installed another Windows own 10.  It worked and my system boots now in less than 20 seconds.   We can close this thread now since I now have a faster machine fully function.  Thank you!
