USB ports mount regular USB devices on MBP Retina but will not recognize cards/reader. Card reder is a Lexar Professional USB 3.0 Dual Slot Reader Reader. Any idea why it is not recognized?
thanks
There are reported problems with the USB 3 ports on the new MacBook Pros. Some do not work with USB 3 devices at all, some work with only USB 2 speeds. I imagine that a firmware update will be necessary to fix the problem.
Sorry,
Clinton
I just posted this "user report" separately. It might address the issue, if you still have the problem, and like me you tried everything else. Good luck.

A user report: fixing an intermittent problem with files on CF cards failing to import, via a Lexar card reader.
I recently encountered a problem: raw files failing to import to Aperture from a Lexar CF card, via the Lexar USB 3.0 card reader, attached to my MacBook Pro retina.
Long story short: the following sequence fixed the problem.
1. Unplug card reader from MBP.
2. Insert CF card completely in card reader.
3. Plug card reader in MBP.
Lexar customer support recommended this sequence to me, when I called them for help. The very helpful person I spoke with said that Lexar has received reports of the problem with some Macs (and some Windows), but Lexar does not know the reason for the failure to import. The remedy works.
Much appreciated I will wait for a fix.
Thanks
Hi Jeff,
Any luck with the firmware fix, i've got time to send back the drive for a full refund, also will the firmware fix work for the next version of lion?
Thanks
Hahahahahahaha I look forward to the update. Thanks
Excellent news. Can't wait to try it out.
Thanks downloaded the firmware, works well, how would i see the data transfer speed? thanks
All set!!
Thanks Tony. Yes, that worked for me too. Now finding it no problem when USB is inserted and transfer rates are much quicker.
Don't forget to 'like' my solution 😉
Thanks
Done 🙂
Jeff, thanks a bunch for keeping us informed. This is good news 🙂
Bad news here! Just ran the Lexar firmware update (Firmware 554) that was supposed to fix the problem. And, drum roll please, IT DOESN'T WORK! Called Lexar this morning and they have no answer!

554 is the old firmware!
You should be loading version 1.0.0 which shows being posted yesterday.
I ran the firmware update download from Lexar, ran the program, and still doesn't work. Called Lexar four hours ago and am still waiting for call-back from Level 2 tech support.
MBP retina won't recognize Lexar USB 3.0 reader. Any ideas why?
