USB tethering lost after downloading I-tunes 10.7

First was your friend using lion on his mac? Second if so then your problem might be using snow leopard. You may want to upgrade if you are able to. I understand that power pc's can't upgrade to lion but if you are able to upgrade then I suggest going to Mountain Lion as I am not having a problem tethering with my macbook air running ML.

I have same problem after update iTunes 10.7 on snow leopard. my iphone 3gs personal hotspot not running on usb cable, but still run on bluetooth pairing. Please apple, fix itunes 10.7 😟

---waiting for iOS 6--- tik..tok...tik...tokkk

Same problem here - I lost iPhone tethering over usb after the iTunes 10.7 upgrade.

I previously had usb tethering fail after upgrading to iTunes 10.6.1 earlier this year. This was the problem of the iTunes upgrade installing a copy of AppleUSBEthernetHost.kext that didn't seem to work properly under 64 bit systems, which seemed to happen when you were also running the iPhone configuration utility -- see https://discussions.apple.com/thread/3787866?start=0&tstart=0. That problem was solved by fixing AppleUSBEthernetHost.kext, then going through some steps to make sure that things have the right permissions.

After upgrading to iTunes 10.7 a few days ago, I lost USB tethering again. However the previous fixes don't seem to work. I've tried several old versions of AppleUSBEthernetHost.kext, and several reinstalls of iTunes.

FYI, I'm using Mac OS X 10.6.8 runing on a MBP (Mar 2011, v 8,2) and I'm using an iPhone 4S. I just upgraded to iOS6 and had the same problem both before and after the iOS upgrade.

Tethering over BlueTooth still works for me, but I'd prefer to get the usb running again.

Not sure if the iTunes 10.6.1 upgrade problem is related to the 10.7 upgrade issue, but this is the second time that an iTunes upgrade has clobbered usb tethering.

Hi All,

I had this problem with the last iTunes update as well. I've done as the rest of you and restored /system/library/extensions/appleusbethernethost.kext from a backup and all is well. Apple has about cured me of updating iTunes. The new .kext installed with 'Tunes 10.7 is 119kb and the one prior to 10.6.3 is 189kb. The 189kb one is the one that works for me. I tried just replacing the .kext in system/library/extensions/appleusbethernerhost.kext/contents/macos and this did not work for me. Therefore replace the folder in system/library/extensions.

rots o' ruck

Thanks for the help...and instructions.

Solved my problems here.

Good morning! I have a problem with tethering to my iMac (operating system 10.6.8, iTunes 10.7) - never worked (I tried first time yesterday)...while with the same iPhone (3G, software 4.2.1) I can use tethering with my MacBookPro (operating system 10.5.8, iTunes 10.3.1). In my iMac I cannot see anything in Preferences/Network while in MacBookPro there is the connection which I named iPhone USB. It seems my iMac can't see the function Tethering fron iPhone...can anybody help me? I tried to replace the file AppleUSBEthernetHost.kext (the file from MacBookPro (may 2009) instead of the one of iMac (March 2010) but it doesn't work...and I'm afraid to make the same with the whole directory...HELP, ME PLEASE!

Thank you! I copied the entier packate (AppleUSBEthernetHost.kext) from an old backup, rebooted and the problem was solved

And that's what I did but it doesn't work! I'm almost desperate...can anybody help me?

What if I have TimeMachine disabled? No way to obtaining a working KEXT file?

I had the same problem with OSX 10.6.8, iTunes 10.7, iOS 6. USB tethering no longer worked but WiFi tethering was ok. Following the advice on this thread I fixed this by reverting to the previous version of

/System/Library/Extensions/AppleUSBEthernetHost.kext

Thanks for the help.
