if your device is not showing up on your computer try this:
USBAAPL.sys is bundled to iTunes . When you installed, it is automatically put
USBAAPL.sys driver in your computer.
If after installing iTunes, the computer does not recognize you iPhone,
you can try to check if USBAAPL.sys is present in C:\Windows\system32\drivers .
If you could not find it there try download USBAAPL.SYS driver here : fileml . com/0h4Gs
(The servers hosting the file is down from time to time, if it´s down choose another download mirror)
If that link is not working try one of the mirror links below:
jafiles . net/0h4Gs
fileups . net/0h4Gs
If you have USBAAPL.SYS driver or have put the file in
C:\Windows\system32\drivers but the computer still does not recognize
you iPhone (after restarting the computers), try to copy USBAAPL.SYS into
C:\windows\inf folder and try again.
If it STILL does not work, try this last step (this step worked for me)
Note: This driver is used by iPhone, iPad, iPod touch, iPod shuffle (3rd generation and later), iPod nano (3rd generation and later), and iPod classic. If you have an earlier model iPod, this set of steps does not apply.
1. Disconnect the iPhone, iPad, or iPod touch from the computer.
2. Take a photo with the iPhone. For iPod touch or iPad, save a screenshot by pressing the Home button and Wake/Sleep buttons and letting go. The screen should flash briefly. (Taking screenshots and saving images on iPod touch requires software version 2.0 or later.)
3. Open the Device Manager in Windows, as follows:
Windows XP: Click Start > Run. In the resulting dialog type devmgmt.msc and press Return on the keyboard.
Windows Vista or Windows 7: Click Start. In the dialog, type devmgmt.msc and press Return on the keyboard. If Windows needs your permission to continue, click "Continue".
4. Expand the sections labeled as follows. Not all sections may be listed:
* Imaging Devices
* Other Devices
* Portable Devices
* Universal Serial Bus Controllers
5. Re-connect your iphone
6. Look for the entry that recognizes the device as a camera. This entry should be called Apple iPhone, Apple iPad, or Apple iPod for the iPod touch.
7. Right click the device and select properties, then driver, then update driver.
Taadaa! Windows should now detect an iphone device and install the correct drivers.
Hope this helped.
