I have been trying to plug my iPhone 4s into my computer, so I can sync my new music onto it, but my computer is not recognizing it for some reason. A message that says "One of the USB devices attached to this computer has malfunctioned, and Windows does
not recognize it. For assistance in solving this problem, click this message", keeps popping up every time I plug in my device. When I click that message, in Device Manager, my Iphone is bolded with the words "unknown device", and I noticed that I don't see
the Apple Mobile Device Ethernet located in Device Manager like it used to be, but that isn't the problem. It didn't work with the AMDE located in DM. When I click "unknown device", Code 43 is shown "Windows has stopped this device because it has reported
problems". What's even weirder is that my computer has installed the driver for the "unknown device", but it still doesn't recognizes it. I checked all of my devices in Device Manager and all of it is working fine.
What I have tried:
- I tried uninstalling and reinstalling iTunes
- Stopping and restarting the Apple Mobile Device and Bonjour under "services".
- Disabling, enabling, uninstalling, reinstalling "Unknown Device", all of my USB ports about a million times (It worked for a split second and then it broke again)
- Tried using different usb cables
- Tried using different usb port for each usb cables
- Unplugged my computer for 30 seconds and plugging it back up
- Restarting my computer
- Took out my battery for 30 seconds and put it back in
- Made sure automatic updating is turned on
- Checked for updates in Windows Updates
- Made sure iTunes and my iPhone 4s is up to date
- Ran Hardware and Device Troubleshooter
- Did System Restore
- Charged my iPhone fully
- Turned my iPhone off and on
- Restarted my iPhone
- Updated the driver for the 'unknown device' with it saying it was supposedly up to date
- Screenshot my iPhone and checked to see if it showed up as a camera in Device Manager; it did not
- Stopped and Restarted all Apple devices in "Services"
- Did itunes diagnostics
- Closed all opened apps on my iPhone
- Made sure my computer is up to date
I tried everything and nothing worked. I searched all over the internet for solutions and no solutions so far. I even tried Apple Support and checked their forums and nothing. Please help, I want to sync my iPhone again.

My problem only started recently like a few weeks ago. It used to recognize my iPhone and sync my music and stuff, but now it doesn't for some reason. It does the same to my brother's old computer. I haven't synced anything, since July 3rd, it says because
I didn't have my computer since then and until now, so I have been using my brother's old computer and it worked fine, until after New Years Day. Then all of a sudden it doesn't want to recognize my iPhone. I thought it was because my brother's old computer
was old. It's about 5 or 6 years old, so I thought that was the reason, until I tried to plug it up to this computer. Now, I have no idea what's going on.
