Missing USB Mass Storage Device driver

I recently bought a new ipod and my laptop was not finding it, so i searched for an anwer and was told to uninstall the apple usb driver and the usb mass storage device, then plug it in. It worked at first, but now both drivers are gone and two have some yellow triangles by them,and when i try to update the drivers it says something about a code 39. How do i get back the 2 missing drivers and fix the code 39's. I have no idea what to do (im not very good with computers). Someone please help!

Hello Clueless96, welcome to the forum

Try this, take your time and work through it line for line, it is not as hard as you may first think;
General USB problems
After a USB device is installed and then removed Windows hides the driver this first part makes all hidden drivers visible.
Remove all USB devices
Click on start orb, Type Advanced System settings in the search box and click to go there.
Click on Advanced tab, Click on Enviroment Variables.
Under the window System variables click on New.
Type " devmgr_show_nonpresent_devices" (without the ") as the variable name and type 1 as the value.
Click ok 3 times to close the windows
Click on start orb, Type Device Manager in the search box and click to go there.
Click on View, Click on Show hidden devices.
Now you can uninstall all old and unknown USB devices. I think it will be best if you uninstall all USB devices
The infcache.1 file is used to store information about USB drivers, the information in this file may have become corrupted or may cause windows to load the wrong driver or cause a driver not found message to be generated.
Deleting this file will force windows to generate a new infcache.1 file
Right click on the start orb and select Windows Explorer,
Select Computer in the address bar and search for infcache.1
Right click on the file infcache.1 (if you have more instances of Windows installed only do this for infcache.1 C:\Windows\System32\Driver Store)
Click on properties, Click on security tab, Click on Edit, Click on Add
Type Administrators In the window with the blinking cursor, Click OK
Place a tick in the box under allow to the right of Full Control, Click Apply, Yes and OK
Delete the infcache.1 file
Connect a USB device, but not the one you were having trouble with to make a new infcache .1
New Start the PC and try your device again.

I thought you needed iTunes installed in order to get the drivers.

All this will do,

Part one makes all drivers visible in Device manager as drivers are normally hidden when you remove a device.

Part two will delete the infcache.1 This file stores the locations of drivers on your PC but it can become corrupted which will cause you to get messages that drivers cannot be found /or installed, even if you point the device to a driver location.

Code 39 means "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)" and one of the remedies is to go through my post.

When you follow my post through to the end a new infcache.1 will be generated hopefully solving your problem.

Nothing else on your PC apart from the old infcache.1 should be harmed.

I am presuming that if you have installed a USB device that is not automatically installed by Windows IE. an installation CD, that you still have the installation media to reinstall these devices when you are finished.

These may help you to decide
System Restore
System Restore Point - Create
It maybe wise to print a copy of the tutorials for a worst case scenario although I have tried my own medicine and it harmed nothing on my PC
