Yes so please elaborate with some details.
I have 2 usb2 external drives--a sea gate and a wd. One sits in a standard usb2 external enclosure. The other is in a Voyager caddy with a usb3 output. They both work fine in other macs with a usb2 port. On the standard enclosure, the retina doesn't even recognize the drive. On the voyager , it erecognizes the drives but either can't read it,reads it horrendously slowly, much slower than USB 2 speed, or freezes the whole Mac, depending on its whim.
I was looking for similiar issues on the net for several hours now, at least now i know i am not alone. I tried plugging in my iPhone to the left USB on the MBPR and nothing happens. I plugged it in to my right USB, and it worked.
Is this what you mean?
I only tried the left side and quit in disgust. When I get home, I will try the right side
Thanks, but it doesn't. I read that document twice. :( it talks about using USB3 devices. We are talking about USB 2 devices.
Oh, also I updated the software before I tried the USB.
I just got back from the Apple Store, and the genius tried the same stuff I tried( the left slot worked for their iPad, but not their iPhones). So he said my MBPR will be replaced as soon as they restock. Weird problem.
I have had the same problem as Rcynic with my MBPR. The left hand side USB port wouldn't detect my iphone (or if it did, it kept unmounting it), but it was fine in the right hand side.
I too sort advise from Apple, although i bought my MBPR through a reseller. They said they didn't know of any problems with the USB's, however they suggested going back to the reseller, which i did. The reseller has agreed to replace my MBPR, so i am waiting for it to come into stock!!
I would appear there is some issues with USB3 at the moment IMO,
