MBP retina won't recognize Lexar USB 3.0 reader. Any ideas why?

I've installed the firmware on my new Macbook Air but it still isn't finding the card reader. You've obviously tested it on a MBP, but did you test on a MBA? Anyone else got it working on the new MBA using the new firmware?

Hi,

I still had issues with the MBP retina installing the driver as it wouldn't find the lexar card reader, these may be applicable to the MBA too.

I unzipped and installed the package, the computer needed to be re-booted.

Then I went into applications and found the Lexar Firmware updater 1.00 and ran that.

This is when I came into issues as the firmware couldn't detect the reader, I pulled the USB half way out of the MBP and only then the firmware updator found a device attached. I then clicked start to update the firmware.

Now when I attach the reader the MBP regonises the reader. It's not a good way to install the driver, but thats the only way it worked, now i need to calculate the speed at which the reader works to see whether it's faster than the USB 2 version.

Hope it helps

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 🙂

You do not need to pull out the cable half way. Once the software is installed, you will need to replug in the reader so that the Mac recognizes it as a device and then the software will let you upgrade the firmware. All should be good from that point forward.

Hi Jeff,

I did try that prior, even re-installing the software and re-booting the computer a few times. Then i remembered how i installed the previous firmware, which was to remove the USB half way until the computer detected a device.

It's all working now, so thats good.

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.

Yeaaaaah! Just downloaded the update (the 5th time today) and this one worked. I suspect that the download version at 10:00 a.m. this morning was changed (after I called to tell Lexar of the problem I was having) to a working version this afternoon (at 2:33 p.m.). Finally have a working USB 3.0 Dual Card Reader!

I've downloaded the firmware update, but it's not showing up in my applications folder? Any ideas why? v0.97 showed up, but 1.0.0 doesn't seem to create a folder with a file to run? Where do I find it once it's installed?

It should be in Applications, folder is “Reader FW Update Tool_FWLX01(UDMA7 Support) V1.00”.
