Apple Mobile Device Usb Driver Windows 7 Code 52
According to: Why does Windows not recognize my USB device as the same device if I plug it into a different port? You may have noticed that if you take a USB device and plug it into your computer, Windows recognizes it and configures it. Then if you unplug it and replug it into a different USB port, Windows gets a bout of amnesia and thinks that it's a completely different device instead of using the settings that applied when you plugged it in last time. The USB device people explained that this happens when the device lacks a USB serial number. Serial numbers are optional on USB devices. If the device has one, then Windows recognizes the device no matter which USB port you plug it into. But if it doesn't have a serial number, then Windows treats each appearance on a different USB port as if it were a new device.
(I remember that one major manufacturer of USB devices didn't quite understand how serial numbers worked. They gave all of their devices serial numbers, that's great, but they all got the same serial number. Exciting things happened if you plugged two of their devices into a computer at the same time.) But why does Windows treat it as a different device if it lacks a serial number and shows up on a different port? Why can't it just say, 'Oh, there you are, over there on another port.' Because that creates random behavior once you plug in two such devices. Depending on the order in which the devices get enumerated by Plug and Play, the two sets of settings would get assigned seemingly randomly at each boot.
Today the settings match up one way, but tomorrow when the devices are enumerated in the other order, the settings are swapped. (You get similarly baffling behavior if you plug in the devices in different order.) In other words: Things suck because (1) things were already in bad shape—this would not have been a problem if the device had a proper serial number—and (2) once you're in this bad state, the alternative sucks more.
The USB stack is just trying to make the best of a bad situation without making it any worse. Windows (as you don't state you OS I assume this is what you are using) associates a device with the port it is plugged into, so it considered 'USB DISK A in port X' to be different from 'USB DISK A in port Y' and it links up the drivers and registry entries accordingly. If you use the 'show unattached devices' option when viewing Device Manager, you will see the device attached to all the ports it has ever been plugged into but greyed out as it isn't currently in them.
When you plug the device into one of these ports Windows will just activate that driver instance, when you plug it into another port it will need to define a new driver instance for that port before activating it (which is the process you see as a user displayed as 'adding new device'. This allows you to have to identical devices plugged into different ports working at the same time. There are other ways to achieve this, with little or no practical difference to the end user which technique the OS uses, but that is how Windows chooses to arrange it.
Hi, I had an issue whereby my iphone 3GS will not appear in My Computer as another drive. It appears in iTunes fine though. Upon plugging it in I see a message 'driver was not installed successfully' and Device Manager just shows an exclamation mark against 'iphone' under Other Devices. It also says:. The drivers for this device are not installed. (Code 28) There is no driver selected for the device information set or element.
To find a driver for this device, click Update Driver. I have reinstalled Windows 7, reinstalled itunes, uninstalled and reinstalled the iphone from device manager, tried to search online for the driver but nothing is working. A few people have reported this but there is no clear fix. Any thoughts? I could take the driver from my windows 7 Starter laptop but not sure which/where the driver is. Hope you can help Thanks Chris. I recently read an article where similar symptoms were occurring but in this case it dealt with USB flash drives.
The user(s) did most of what you did to try to resolve your iPhone problem. The miracle fix ended up being a cold reboot of the motherboard - that is, unplug the PSU.
Apparently the mobo capacitors needed refreshing for the USB ports to wake up again. Like you, the users were experiencing weird issues where some USB devices were fine but could not get the USB flash drives to initialize. Looks like you've done everything else.

It may be worth a try being so simple. Chris3966 wrote: Not 100% on the motherboard issue, yet why would the iphone be available in iTunes, just not as a USB drive in My computer. I should note that I, too, had this same problem on a previous Win7 64-bit install which I tried everything, including a call to Apple support. The only thing I did not do is an o/s reload. But you already indicated that you did a reload, so I was merely offering something I ran across as a possibility, obscure as it may seem.
In my case, a reload did the trick but in your case it apparently did not. Do USB flash drives work properly in the machine? If not, I wouldn't discount RSturba's advice on powering the machine off and releasing all charge from the motherboard.

It's actually not a motherboard problem, per se, as I've only seen this problem with Vista/7, but it is quite common. And, it will always tell you that the drivers were not installed for USB devices. It does only seem to affect storage devices, though. Keyboards and mice will work just fine.
If that's not the problem and you've reinstalled Windows, it could very well be a problem with the iPhone itself and/or the cable. Are you able to attach it to another machine without problems?

If you have Windows 7 Ultimate N, it appears that the iPhone and iPad will not show up in Windows Explorer, thus you cannot retrieve photos from them. The 'N' means that Windows Media Player is not installed, which prevents the iPhone and iPad from being recognized by Windows Explorer.
To solve it, you must download Windows Media Player from Microsoft and install it. Search for: Windows 7 Ultimate N Windows Media Player Once installed and the computer is rebooted, your iPhone and iPad will show up in Windows Explorer.

The 'N' means that Windows Media Player is not installed, which prevents the iPhone and iPad from being recognized by Windows Explorer. To solve it, you must download Windows Media Player from Microsoft and install it. 3 hours of installing and uninstalling and nobody apart from you have picked up on the simple issue that you need media player. Not even microsoft.
Thank you so much for solving this!! I'm so grateful to have found this page. After trawling through the various apple forums where various f.kwits regularly post about 'disabling anti virus' or 'installing iTunes' it's great that someone with some actual functioning brain cells is able to articulate the problem and give a bang on answer.
Another fine specimen of a moron tried to tell me that error 28 indicated a hardware failure, when the error code explanation of 'drivers aren't installed' is next to the error itself and the phone worked in iTunes. I've been suffering with exactly the same symptoms and I just recently installed Ultimate N edition.
Absolutely no idea why not installing media player etc will fail to download an iPhone driver for explorer but there we are. Grabbing the feature pack now to install WMP 12 and fingers crossed that will work.
Short of that working, another trip to MSDN and grab a non N version of the software I guess. Many thanks again, it would be helpful if Apple or Microsoft could actually have just written this somewhere.
