iTunes 10 does not detect my iPhone

i recently upgraded to itunes 10, and i have a 1st gen iphone. after upgrading, i synced my iphone and everything went fine. soon after that, i had a totally unrelated hard disk drive failure. luckily all my data were backed up, apple replaced my hard disk, and i restored all my data. however, when i tried to connect my iphone to itunes to sync, itunes would not detect the iphone. i tried many fixes, the only one that worked was to reinstall itunes 10 (which is a pain, because you have to get rid of lots of files.) last night, after reinstalling itunes 10, i connected my iphone and itunes detected it and synced. i thought the issue was solved for good and maybe was related to the restoring of the backed up data. however, i just tried to sync again, but the problem has re-appeared. my itunes does not detect my iphone.

the console message i get is as follows:

9/7/10 3:56:17 PM usbmuxd[30] connect_toport (thread 0x100581000): Could not connect to USB mux port 32498 for device 2: Connection refused
9/7/10 3:56:17 PM usbmuxd[30] MobileDeviceConnectlocked (thread 0x100581000): Could not connect to lockdown port on device bac8e3086978950d97c077103aa8996ccb56eec1.

i thought that usbmuxd is built for linux, but is it doing in itunes 10? but it must belong to it, because i also got this (i think when booting, but i am not sure):

9/7/10 3:33:40 PM com.apple.usbmuxd[30] usbmuxd-201 built for iTunesTen on Aug 12 2010 at 17:33:03, running 64 bit

what is going on? i don't want to reinstall the **** itunes every time i have to sync. any solution? thanks

MacBook Pro 2.8 GHz Intel Core 2 Duo, Mac OS X (10.6.4), 1st Gen iPhone 8 Gb FW 3.1.2

update:

reinstalling itunes 10 does not work anymore. i did it again, and this time wasn't able to sync at all. itunes simply does not see my iphone. i found similar posts that predated itunes 10, so i doubt the new version is the culprit. from my cursory reading of posts on the web, the crux is the kAMDMuxConnectError. i found one user that had similar problems after migrating his system from one computer to another. so, maybe restoring my backed up data may be the culprit. but what to do now? should i reinstall the system? i'd rather not, unless absolutely necessary.
any comment will be greatly appreciated

I have the same problem. I migrated to a new Macbook with Snow Leopard, using the Migration Assistant. Most things went smooth, but iTunes does not detect my iPhone (3GS - jailbroken on iOs 4.0.1). Also, I cannot find the backup file I could use to restore. There is no ~/Library/Application Support/MobileSync folder.. (it should be there?)

Solved: Go to the Apple logo in the left top corner and click on Software Update. Apple brought out a Software update especially for this and I installed it. Syncs perfectly now.

good luck

PS. If not, try signing out / in in iTunes and authorize your computer.
PPS. Otherwise you might want to reboot the iPhone while connected, then it will recognize but you will have to restore the iPhone, and you don't want that.

Apple logo in iTunes? )

I updated to iTunes 10.0 and now my iPhone can't sync with iTunes. iTunes does not recognize the phone. Windows sees it as Digital Camera.

I see your are running a Windows operating system, that may be the difference. Few hours after I started this thread Apple released a software update for the iPhone SDK software. That update solves the problem. I do get those updates automatically because I installed the Developer's Tools on my Mac. Call Apple Support, they'll find a way to help you out

I downloaded iTunes 10 under Windows XP and have had the same problem as you describe since then. "My Computer" recognises the iPhone as a camera only, and iTunes doesn't list it as a device. I have followed the recommended steps of uninstalling and re-installing iTunes, making sure I have the latest version of XP and looking for conflicts with other devices using MSCONFIG, but nothing helps.

Did anyone find a solution?

the solution is in the iphone SDK sofwtare update. uninstalling and reinstalling itunes is only a temporary fix (if it works; it worked for me but then when you reboot the problem re-emerges). apple is aware of this problem, since they release the update of iphone SDK only to fix it. if you do not get those update because you don't have the developer's kit (or tools, can't remember) contact apple. they'll help you out

I had this problem with an iphone 3G that I inherited to use as an ipod, after my wife upgraded to an iphone 4. II finally got the 3G to show up in iTunes--I don't remember now how--but after a restart it would again not be detected, and the only fix I discovered was to reinstall iTunes after a restart. Workable, but a nuisance.

I now have a permanent fix, thanks to Ted Landau's Mac 911 at MacWorld.com. See http://www.macworld.com/article/156156/2010/12/itunesiphonedisagree.html

He suggests deleting the file com.apple.usbmuxd.plist~orig, located in /System/Library/LaunchDaemons. Don't delete the similar file com.apple.usbmuxd.plist. This worked for me both in iTunes 10.0 and 10.1. Recognition of the phone is consistent now and survives a restart.

Landau says there's an Apple support article suggesting deleting additional mobile-device-related system files, restarting, and reinstalling iTunes if the usbmuxd fix doesn't work, but he doesn't identify the article.

OStockman I have done exactly the same with the same result (ie no success). Also the last forum post from barryrb (with the article about deleting the file) seemed only to relate to Macs, as I couldn't find that file on my PC.

Did anyone offer you any helpful advice yet? I'm finding it really frustrating!
