Unknown error 9 ipod touch, iphone, itunes


Error 9:

This error occurs when the device unexpectedly drops off of the USB bus and communication stops.

This can occur if the device is manually disconnected during the restore process.

This issue can be resolved by performing USB isolation troubleshooting, using a different USB dock connector cable, trying another USB port, (DO NOT USE HUBS) restoring on another computer, or by eliminating conflicts from third-party security software.

Hello,

This sometimes happen when static hits your system. Try this next time, hold the ipod/camera usb cord in one hand and the touch your pc with the other. (This will ground you to the pc) Then plug in your equipment. Good luck

USB Troubles


How To Refresh and reinstall USB Ports Of Your Computer Hello there, the other day i tried refreshing and reinstalling the USB ports on my PC, as some of my connecting devices are not recognized. I present the detailed procedure on refreshing the USB ports.
Let’s go!!

Here are the steps to refresh/reinstall/uninstalling the USB ports on the computer.

The USB port needs to be refreshed to make sure that no other device has captured the USB port of the computer. The Mouse, video camera, your external USB hard disk; what ever it may be.

Follow the steps given below to refresh USB ports.

1. Right-click My Computer icon on the desktop, and then select Properties.
2. Click the Hardware tab.
3. Click the Device Manager Button.
4. Click the plus (+) sign to the left of Universal Serial Bus controllers.
5. Right-click the device listed under Universal Serial Bus controller and select Uninstall.
6. Click OK to confirm the removal of the device.

Please note, repeat Steps 5 and 6 until all the devices under Universal Serial Bus Controller are removed.

7. Shut down the computer.

CAUTION: Ensure that the Shut Down option is selected, instead of the Restart option.

8. Wait for 5 seconds and then restart the computer. When the computer restarts, a "Windows has detected new or added hardware" message window will open.

The above steps will refresh the USB ports.

Now connect the USB devices like mouse, video camera, your external USB hard disk...USB hubs...whatever you like and the drivers should install automatically.

Tip: It is always recommended to connect the main USB devices at the rear end USB port. As they require more power to initiate.


The above steps are for XP operating system. When coming to the matter of Vista, please note the changes below:
===========================
1) Right-click Computer icon from the desktop , and then click Properties to open the System Properties window, and then select the Device Manager tab.

2) Click the Plus (+) sign next to Universal Serial Bus Controllers/Root hub.

3) Click the USB Composite Device entry to highlight it, and then click Remove. If a screen appears to confirm the deletion, confirm the deletion.

4) Disconnect the USB cable to the all-in-one, wait a couple seconds, and then reconnect the cable. This should restart Windows device detection (Plug and Play).

5) A New Hardware found screen may appear, click next through all of the screens that appear for the Wizard to install the USB Composite Device. Click Finish once the wizard completes.

My USB ports no longer detect devices when plugged in.


Updating, or in some cases reinstalling, the drivers for your computer's USB interface should resolve this issue.
Locate the iPod in Device Manager
  1. Connect iPod to the computer.
  2. Quit iTunes if it launches.
  3. On the Start menu, click Control Panel.
  4. In Control Panel, open Administrative Tools. Note: If you don't see Administrative Tools, look at the left column in Control Panel for a link that says, "Switch to Classic View," and click it.
  5. Double click the Computer Management shortcut.
  6. In the left column, click on Device Manager.
  7. In the right column, click the plus (+) icon next to Universal Serial Bus controllers to expand this selection.
  8. Locate the iPod in this list. In some cases one of the entries will have "iPod" in its name. If no such entries are present, the iPod is most likely represented by "USB Mass Storage Device."
  9. Note: A red "X" appearing next to the iPod's entry in Device Manager indicates this device is disabled. To enable this device, right-click its entry in Device Manager and choose Enable from the shortcut menu.
  10. Update the USB driver
    1. Right-click the iPod's entry in Device Manager and choose Update Driver from the shortcut menu.
    2. In the Hardware Update Wizard that appears, select "Yes, this time only" to allow Windows to connect to the Windows Update Website. Click Next.
    3. Select "Install the software automatically (Recommended)" and click Next. Windows searches for updated drivers and installs any it finds. If Windows is unable to find updated drivers on its own, continue with step #4.
    4. Click Back.
    5. Select "Install from a list or specific location (Advanced)" and click Next.
    6. Select "Search for the best driver in these locations."
    7. Select "Include this location in the search" and type the following in the field below: C:\Windows\INF
  11. Click Next. Windows searches this location for drivers and installs any it finds. If Windows is unable to find updated drivers on its own, you must reinstall the USB drivers as shown below.
  12. Note: During installation, if a message appears stating that the software you are installing "has not passed Windows Logo testing" click Continue Anyway to continue installing the drivers.
  13. Reinstall USB driver
    1. Right-click the iPod's entry in Device Manager and choose Uninstall from the shortcut menu.
    2. In the resulting dialog box, click OK.
    3. In the Device Manager window, right-click Universal Serial Bus controllers and choose Scan for hardware changes from the shortcut menu.
    4. Windows automatically reinstalls the necessary USB drivers and attempt to remount the iPod. Regards...

Power surge on hub port


Try this to find out which one of your components has an issue. Turn off your machine then unplug all of your USB cables. Turn your machine back on and plug in one of your USB cables. Verify the component you just plugged in works correctly and if it does plug in another cable and verify that component is working. Continue these steps until you have the one component that displays the error you have seen. That component is most likely the cause of your issue and should be replaced.

Good luck, Greased.

Where do you connect a digital camera on your computer?


how old is this "older computer"
It may not matter, what im thinking is that you could pick up a card reader from any electronics store and plug it into your usb. Then your computer will see the reader as a removable device in my computer. This would be the easiest way.

The other way is to first install the software that came with the camera. Then plug the camera into the usb ports and transfer the pictures thruough the program that came with the camera. Sometimes this can be tricky and not work 100% the first time.

Also what kind of camera do you have ?
What kind of OS are you running XP,Vista,etc.?
What kind of card are you trying to get the pictures off of?
