Since no make, model of the host computer is listed or I missed it I can only see that it's been discussed before at this link.
I have an iPod (refurb, OS4). My computer will only recognize it as a camera (I followed the steps recommended in Apple support when your computer won't recognize your iPod and I was able to get far enough with the steps to make a screenshot and thus get that minimal recognition, before that my computer wouldn't recognize it at all). I have discovered that when I install iTunes, the drivers usbaapl.inf and usbaapl.cat aren't being installed (and yes, I have uninstalled and re-installed iTunes repeatedly). I have read that using a program called WinRAR you can extract those files from iTunes.exe and install them manually. Can anyone tell me how to do that?
