USB Ports not recognizing installed devices

The computer is not recognizing the device because the appropriate software or driver is not installed on the device.

Most of the time when you connect a smartphone into a compatible laptop the device drivers or software automatically install, so the laptop may recognize the smartphone.

Here are some possibilities as to why the device is not recognized.

1) The USB port is bad.
2) The USB port is not activated
3) One of the devices does not support the other

Here are a few possible troubleshooting solutions:

1) Go to the smartphone manufactures website and download and install the updated device driver and software then plug in the device to see if it is recognized.
2) (if Windows OS) Go to the Device Manager to see if the device is showing up when it's plugged in. If you see the device in device manager right click the device and choose to update the driver.
3) (if Windows OS) Additionally, in device manager you can check your device's USB ports to see if there is an issue with the ports that may be resulting in the smartphone not being recognized. You can choose to re-enable the USB ports or update the software for the USB ports.

Hopes that helps resolve your issues.

• Check system requirements. - iPod nano (5th generation) requires the following minimum versions of Windows: either Windows XP (Service Pack 3 or later), Vista or Windows 7. If you have one of these versions of Windows, verify that Windows is fully up to date by downloading and installing software updates from Microsoft. If you have Windows XP with Windows XP Service Pack 1 or Windows XP Service Pack 2, download and install Service Pack 3 using Windows Update.
  
  
• iTunes online? - Confirm that iTunes has been downloaded and installed.
  
  
• AMDS online? - iPod nano requires Apple Mobile Device Support (AMDS), which should be automatically installed with iTunes. To verify whether it is installed, click Start > Control Panel. Open the Add or Remove Programs control panel and verify that Apple Mobile Device Support is visible in the list of currently installed programs. If it is not, remove and reinstall iTunes.
  
  
• Check USB connection. - Disconnect all USB devices from the system with the exception of the iPod nano and any USB keyboard and mouse. Then restart your computer. Verify that you are using a high-powered USB 2.0 port. Test with an alternate iPod USB cable if one is available.
  
  
• AMDS - Re-verify that AMDS is running and installed.
  
  
• iTunes usage - Remove and reinstall iTunes.

hope this helps

Sometimes windows XP doesn't install the driver to recognize your USB ports. For example, a fresh install of XP does not contain any driver for sound or graphics. The best way is to update your windows XP up to Service Pack 3 by installing SP1 and SP2... etc, it will take a looooooooong time, but your PC would be better.
To check whether or not you have any USB drivers install just go to control panel and then device manager. Look for Universal Serial Bus (USB)

If the laptop was "designed for Vista" or "designed for Windows 7", then it's quite likely that the manufacturer did *NOT* create any device-drivers for Windows XP. Thus, you'll be missing support for your LCD screen, your wired/wireless network adapters, your USB-ports, and so on.

Note that Microsoft will stop supporting Windows XP Service Pack 2 as of July 15 this year (2010). So, trying to install an "unsupported" operating-system is *NOT* a good idea.

Stick with the operating system that was shipped with the computer.

This problem mainly occurs because Sony does not support connection though Hubs or for that matter Front Panel USB ports. Try connecting the camera throught the back panel ports (There are usually four to six of these depending on your motherboard.) .

If it still remains unresolved:
1. Update windows XP to atleast service pack two (If you havent already). Uninstall Picture Motion Browser.

2. Uninstall the camera from the device manager.
This is how to do it. Connect the camera, wait for it to show as an unrecognised device. Hit "Windows + Pause/Break" to bring up system properties. (Windows is the key next to alt, that brings up the start menu.). Navigate to the hardware tab and choose device manager. Expand the last tree from the list (One for USB devices) and delete the entry "Unrecognised Device" (Select it and hit delete). Shut the device manager. Disconect the camera.

3. Now, connect the camera the one of the USB ports on the back of your PC and power it on. It should show up as a PTP/Mass storage (depending on your camera settings) device.

4. If it still doesn't work, disconnect all other USB devices from your PC and then repeat from step 2.

5. You can reinstall Picture motion Browser if you like or use Xp's photo transfer utility.

Hope this solves your problem.

check if the usb ports are enabled in BIOS.
check if the driver for your usb ports are installed properly.

if you are runninf windows xp than do an update to service pack 2. that should fix the usb problem..... you can do that by going to www.microsoft.com and clicking on the service pack 3 option than you will need to install the update software whitch only take about a min. than press express and the software will scan your computer for the latest updates. you might need to do this 2 times if ou are running with service pack 1.

Install the manufacturer's drivers not microsoft.
