My Macbook Pro Retina's USB port on the right side not working at all

Dear all,

I received my macbook pro 15inch with retina display a week ago, but not until today had I got the chance to use the USB port on the right side, only to find out that it is not connecting to anything at all. I have tried to use my iPhone 4 and iPad 3 with two different cables, my USB thumb drive, and my Blackberry 9900, none of them are charging nor shown in iTunes/Finder. All of above works on the left and on other windows machines too.

I'm also not able to charge my Blackberry with the usb port on the left side, thought it would pop up a message saying "charging not supported" on the phone.

For you information, I have applied both updates including the one released few days ago. I have also tried to reset the PRAM. Also, I have migrated from my old late 2008 13inch unibody Macbook using Migration Assistant, not sure if this would affect anything.

I'm aware that there have been reports and discussions regarding the USB port not been able to run devices on 3.0 speed, but I wonder if anyone else have the same problem with me, where the port simply not connecting to anything at all?

MacBook Pro with Retina display, Mac OS X (10.7.4)

I have the same but worse. I often copy large files between external disks (working with film), and lately I have 3 separate disk broken down in two months!!! I thought this was some kind of extremely bad luck.. but now, reading this thread I think this is a bigger problem... I have figured out that ALL THREE broke down using the right port of a MacBook Pro (Retina, 13-inch, Early 2015) ... In all three cases I did copy large amounts of files TO the disks using usb 3.0 and the copy was interrupted in the middle.

The first disk I had to reformat to be able to use it again, (luckely I had back up) and the disk started to work again. All information lost.

The second disk all information was destroyed and unaccacable on other computers. (luckely I had back up). All information lost.

The third disk totally died. Cant even do a reformat on it. All information lost.

!!! Today another disk went corrupt after copy of large file to the disk. .... now I will leave the computer into service... Now I am almost sure something must be wrong with the right USB port...

After copying large amount of files the USB3 Disk will not mount!! Also the name of the disk disappeared, its now named "disk5s2" .... and greyed out in diskUtility so I can not mount it anymore.... (same thing when checking the disk in another computer)

I suppose everything is lost on this disk.

More often than not this has turned out to be a hardware issue.

Since your system is new, simply make an appointment at your local Apple Store to have it checked out.
