Hi guys,
Everything was ok yesterday but right now when I connect my iPhone 4S to my Macbook Pro Retina display (I've got it yesterday) left USB it keeps connecting and disconnecting. I'm on Lion latest update.
I've tested with another cable same result. Turned off and on both MBPR and iPhone 4S twice didn't help.
No the interesting part that may help: it works fine on my PC all three USB ports. It works on right USB port of my MBPR too. I've tested the left USB port (That has a problem) with other devices. I'm writing this post with an external keyboard plugged to this port. I've tested this port with my iPod Touch and it worked fine. Only happens with my iPhone 4S and this left USB port.
Any suggestion? Is it possible that the USB port not working well? Any way to assure it's fine?
Thanks alot.
Make Genius Reservation and take your equipment to Apple so Genius can figure this out. They have Demo iPhone 4S and Demo MacBook Pros which you can swap around to trouble shoot this perfectly. When it is figured out, they can then completely solve the problem, fix iPhone 4S, fix MacBook Pro or fix both.
Thanks for reply,
I'm far from Apple Store. I'm in Malaysia and G bar here is like testing some simple stuff and they tell you they can't do it it has to go to Singapore.
I've tested the port with another iPhone 4. Works fine! Still has a problem with mine. The only differences here is mine is 4S and it has iOS 6 beta 3.
The other weird thing is, I plug my iPhone to the external Apple keyboard USB port and it works fine too! It only happens when I plug it to the USB port directly.
Is there any chance that the USB has some sort of config or settings for my device and it only set with that port? Any way that I can reset those configuration?
I know here is a user to user place but I'm looking for a solution or tips&tricks or even the same experience before I go to the Apple store.
Thanks.
