• Lightroom does not recognize any of my file types [DNG / JPEG etc] and is unable to import? any ideas for a fix?

  Lightroom does not recognize any of my file types [DNG / JPEG etc] and is unable to import? any ideas for a fix?

  It's impossible. LR is a non-destructive editor and photo management. For her to not see images of the files would make it one of the worst of these programs tyupes.

  So there is a parameter that you have screwed up in the import dialog window that prevents your DNG, TIFF, JPG, PSD, PNG, CMYK and film formats appear in the import window.

  So show us a screenshot of your import window.

  More than likely you have chosen a destination that has all the permissions read/write to your username.

• iTunes does not recognize any of my iPhones (Windows 10)

  I've recently updated iTunes 12.4 and now my iPhone 5s, and my iPhone 4 are not recognized by iTunes. They appear as 'Apple iPhone' in my file Explorer, but are not accessible via iTunes or iFunBox. I tried all the options in the management of the link here:

  If iTunes does not recognize your iPhone, iPad or iPod - Apple Support

  I removed the lockdown folder.

  I tried several cables.

  When I go into Device Manager, there is no "Apple Mobile Device USB Driver" under "In Bus USB controllers", but there is 'Apple iPhone' under 'portable '. If you're looking for an update to this pilot says 'Windows has determined the driver software for your device is up-to-date' "MTP USB device".

  More interesting still, I went down to iTunes 12.1.3, thinking that would take me back to a working version, but in fact it STILL does not recognize my phone(s)!

  What the hell is happening?

  If your iOS device does not appear in iTunes, try the following:

  1. Open Control Panel > Device Manager
  2. Plug in your device
  3. Locate Bus USB Controllers > Apple Mobile Device USB Driver.
     It is also possible that the device may appear under imaging devices, portable devices or other devices or as a device USB of MTB.
     
  4. Right-click and select software update of the driver...
  5. Click Browse my computer for driver software
  6. Go to C:\Program Files\Common Apple Mobile Device Support\Drivers or
     C:\Program Files (x 86) \Common Files\Apple\Mobile Device Support\Drivers
  7. Click on let me pick from a list of drivers for devices on my computer
  8. Click on Apple Mobile Device USB Driver
  9. Click Next, then close and exit the Device Manager

  To step 3 above, open the Device Manager. Expand one of the articles that are listed.

  • USB Bus controllers
  • Imaging devices
  • Portable devices
  • Other devices

  Plug in the appliance. You should hear the telltale Windows sound device connection and a Division must acquire a new entry. This should be your device. It cannot be labelled properly at this point. If you do not hear a suspicious noise cable damaged.

  Or try If iTunes does not your iPad, iPhone or iPod - Apple Support

  If not try a complete tear down and rebuild iTunes in accordance with the resolution of the problems with iTunes for Windows updates.

  Or try to go back to the last version of iTunes that has worked for you. See the programs installation of iTunes to download links. If you roll back to 12.4.0.119 to 12.3.3.17 or 12.3.2.35, for example, then you will also need restore the database of the library in the manner described in the empty/corrupted after upgrade/crash iTunes library. The tip makes suggestions to reintroduce recent purchases, so at worst, you lose a few meters or a newly created playlist.

• HP Envy 15 - q47002 i7: laptop overheating, does not recognize any USB. Even in the Bios.

  Hello

  I bought this product last year, so my warranty wore off.

  My laptop is overheating and it is very slow at this point (even videos are not working well). I tried to clean it up but it was without result.  I want the game and computationally intensive applications, but I'm afraid of the motherboard or hard drive failure.

  Now to the point. I can't install the new OS, any OS because this laptop doesn't have a DVD player and it doesn't recognize any usb 2.0 or 3.0.  I tried to change the options in the Bios and I tried to uninstall and install the drivers (they are up to date).

  What should I do? I can't install a new system because of this problem, and I can't use anything more demanding than youtube which is really annoying since this laptop has good specifications.

  I am currently running Windows 8.1 which I got when I made a purchase.

  I hope someone answers!

  Thank you.

  EDIT: In the Device Manager it says device not installed with yellow exclamation point. By Usb or ext hdd. And it will not find the device-specific drivers. As I never need them on another PC or laptop.

• Satellite Pro U300 OS does not recognize PS/2 Port TouchPad

  I have a similar problem.

  My system doesn't recognize that the PS/2 Port TouchPad exists on my Satellite Pro U300. He acknowledges that it no longer works but when I go to Control Panel then mouse it does not appear in the list of devices.

  Help!

  Hello

  I m do not know what problem describe you exactly.
  Do you mean that your notebook computer touchpad no longer works, or did you mean the USB mouse?

  If you mean touchpad, so you should try to reinstall the driver for the touchpad.
  The European driver Toshiba page provides Synaptics touchpad drivers series Pro U300 for Win XP and Vista.
  But generally the operating system should automatically recognize the touchpad and touchpad should work even using the common internal Windows driver.

• Vista does not recognize any disk in the disk drive

  Vista crashed when I was loading photos on a cd.  Since then every disc I put in - music, software, data are not recognized, it turns but no program starts automatically.  If I go in via Explore and click the drive the disc turns, then I get the message "Please put in a disc.  Any help gratefully received

  Hello

  Please make all below even if you have done some before as it is often the set of operations which solves
  the question.

  Try this - Panel - Device Manager - CD/DVD - double-click on the device - driver tab - click
  Update the drivers (this will probably do nothing) - then RIGHT click the drive - UNINSTALL - REBOOT
  This will refresh the default driver stack. Even if the reader does not appear to continue below.
  
  Then, work your way through these - don't forget the drive might be bad, could be a loose cable or
  slight corrosion on the contacts (usually for a laptop) and other issues.

  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
  contacts data with a pencil eraser.

  Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
  manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

  Hope these helps.

• Mac Pro does not recognize the Ethernet ports

  After a reboot for my end of 2013 Mac Pro OS x 10.11.3, the two Ethernet ports are most recognized. Suffice to say not 'connected' is one of them.

  I have:

  • rebooted a couple of times
  • Reset the PRAM
  • the power disconnected for several minutes left
  • tried two different terminals
  • tried two different Ethernet cables
  • tried the two Ethernet ports

  The light of the end device will blink.

  WiFi works fine.

  What should I do before I decide that there is a hardware problem?

  Bob

  There was a recent post about the same problem and found a solution. Give it a try: Re-built-in ethernet disappeared.

• DVD Sony player appears installed but does not recognize any CD or DVD

  I just bought a Sony Optiarc AD7260 DVD RW drive and installed in my system. I am running Win XP Pro sp3. My Bios says the drive is recognized by the latter and in the Device Manager in Windows, the drive shows up and says that "this device works properly." However, any disk I put in the drive (self burned cd / self burned dvd / retail music cd / dvd retail game / virgins DVD) never presents itself as being accessible. When the drawer goes in, I get the icon of the cd spinning for about 15-30 seconds, but then it goes back to the usual pointer. If I try to access the drive in Windows Explorer or any other program, it does not appear. I tried to use ImgBurn to get media info I had placed in the drive (blanks & with data) but it still says "incompatible medium installed" in the drive. The Optiarc is my 4th Sata device, 3 others are hard drives. The system is a dc7100 HP Compaq with 3 GB of ram. Any suggestions?

  Hello.

  Do you have the old disk, or access to another drive, try in the computer?  If these work then you will have a faulty drive.  It is possible to have a defective out of the box.  Also try a different SATA cable.  These can sometimes be problematic.

  Hello

  Close all programs and Skype.

  Double-click Control Panel / Device Manager - Imaging - writing down of the brand and model of camera.
  on this subject and on the tab of the driver is version. Now, click on update drivers (who are unable to do anything as MS
  is far behind the pilots of certification). RIGHT click on the camera - UNINSTALL - REBOOT - it
  will update the driver stack.

  Now, go to the system manufacturer's website and download the latest driver for the camera and the other related camera

  Just you'd go to Toshiba Support and get the driver for your model laptop.

  Go to your model.

• Why google does not recognize any of the keywords that I put in my page properties?

  In my site built in Muse, I put all the relevant keywords in properties on each page and when I checked the keywords in Google Webmaster tools none of them words are supported. What I am doing wrong?

  Hello

  Some keywords are very competitive. Make sure you check the competition for the search term that you want to classify. In addition, you must check the sites Web which are located upstairs for that keyword. Analyze, observe their optimization tips and try to use these techniques in your optimization process.

  Also, do not rely on keywords or not to optimize your website for keywords, optimizing for users and it will automatically be a higher rank in the search engine results Page (SERP). Also take a look at the official Google blog, which says, is no longer the key words are

  Official Google Webmaster Central blog: Google does not use the keywords meta tag in web ranking
