Q: iTunes 12.3.0.44 does not recognize connected iPad or iPhone

I have the same problem

same here, its getting annoying..

I have the same problem. My PC can see that my iPod touch is connected, but iTunes won't recognize it. I have the latest version of iTunes (tried reinstalling) and my touch now has iOS9.

I have the same problem.  Spent some quality time at the Microsoft Store today in fact... I think it's a windows issue.  Every time, I hook up my phone to my Surface Pro 3 (note, hubby duplicated error on his gaming laptop that was upgraded to Windows 10), the phone immediately gets an inquiry regarding allowing the pc to access photos and videos via the new Phone Companion app that got installed either during or shortly after upgrading to windows 10 in a round of updates that auto installed.  And, when you say - yes, trust, you can now access video and photos from the phone.  All on windows software.

And, it's not just my iPhone/iPad I'm having problems with.  My Olympus Camera - no longer recognized by the pc and Olympus software when I plug it into the computer.  And, I'm having mouse "flaking out" issues.  Windows 8.1 - no issues.  When I first upgraded to Windows 10, I don't recall problems with the mouse and other drivers... now after some updates and I get a moment to work on some things... it's like NOTHING WORKS with this freaking software.  Hoping Apple can get iTunes working with everything, but again -- I'm not convinced it's "just an Apple problem" like they said at the Microsoft Store.

I also walked across the isle in the mall -- literally -- into the Apple Store and asked them about what I perceive to be a driver issue.  The gal suggested I call up Apple Care to get help as the Apple Care personnel has Windows training and will be able to remote in and see what's going on... SO, I'll be scheduling that into my schedule soon.

Personally, my favorite moment of the day was at the Microsoft Store when the geeks looked at me and after having had a geek huddle confirmed that yeah - they were out of ideas... so my options were to revert back -- oops, missed that 30 day set in stone deadline -- or since the 8.1 key is "technically" still part of the machine, I could make an appointment after I travel next week and have them rebuild my computer, which means I loose all the files and have to start from square one loading in software as it's a complete wipe.  OR, I can wait it out and it'll all get fixed eventually.  OHHH and in the meantime, if I happen upon a fix, please let them know, because you know there are a lot of us Apple iPhone/iPad/iPod users who happen to own a PC.

I successfully synced my iPad PRIOR to upgrading iTunes to 12.3.044 from my Windows 10 (not Surface) machine. Therefore I believe this particular problem began with the recent iTunes update.  However, I'm no longer able to directly manage files (pix & vids) from iPhone or iPad from my Windows 10 machine, which has been going on for awhile - so THAT may be more a Windows issue.

I got the same problem after upgrading iTunes on Windows 10. I hope they solve this problem as soon as possible

I have the same issue, win 10 and the new iTunes don't recognize the iPhone or iPad the apple mobile device USB driver is not loading at old also trying to point to drivers at c:\program files\common files\apple mobile device support\drivers\usbaapl64 and still nothing. anyone have any suggestion also deleted iTunes and reloaded again and still nothing

Same problem with ancient iPod Touch after upgrading to 12.3.0.44 on Windows 7 with the message "an invalid response was received from the device."

I have the same issue. everything was good on my windows 10 box until I updated iTunes to 12.3.0.44.  Now iTunes will not see device.  Windows sees it just fine but iTunes will not.

I'm having the same problem... I also have Win 10 64 bit.  The my ipad Air was recognized just before the upgrade to itunes today, but immediately following, i cannot get itunes to see it.  So its NOT Win 10.  Its definitely an itunes issue/bug.  If you have Win 10 x64 and itunes and want to upgrade don't do it right now if I were you. 

I have the same problem on a Surface 3 running Windows 10 for a while only after updating iTunes to 12.3.0.44  -  never had any problem with syncing the iPhone or any other USB driven devices until now. So this seems to be an Apple problem, THEY are the ones who  have to test their software updates on a considerable number of test machines before releasing ot to th world. Well, sh... happens, so  what is needed now are either updates or workarounds so we can all continue work.

BTW, I wanted to do a backup before upgrading the iPhone 6 to iOS 9, so I am still on 8.4 with my problems.

PS: And - dear Apple - while you are at it, please also have a user interface design expert look at the iTunes interface and workflow!-)

Having this same problem on a Lenovo Laptop running Windows 10. I iPod Nano 5th generation synced perfectly with iTunes until the recent iTunes update to 12.3.0.44 64 bit software. I've attempted every fix suggested (uninstall and reinstall iTunes, check for Windows updates, update iPod drivers) to no avail. Extremely frustrating!

Same situation here. iTunes has became absolutely pathetic, especially on Windows computers. I understand Apple wants more OSX users, but honestly, this nonstop problem with itunes (ever since 12.0 came out) makes Apple look bad, not Windows. Pathetic.

Does anyone know usually how long this takes to get fixed? The software was just recently released so I would think that it would get fixed rather quickly but I have been experiencing some rather very annoying things with iTunes and windows so my patience level is at a very low minimum
