I have just purchased a Lexar USB 3 professional dual slot card reader and Lexar 1000x 32GB CF card. When I try to download photos to my Windows 7 64 bit computer, the computer cannot see the files, it reports there are no files on the card. You can see the directories but no files. The images are still available to see when played back in my camera. The card reader however had no troubles in seeing files on my Sandisk 32GB CF card, although it would only see them on a USB2 port. I have just updated the firmware to the latest lx01 from the Lexar website but it has made no difference. I also have a Lexar USB2 professional dual slot reader and it has the same problem and does not work with the 32GB Lexar 1000x card either, but can read my other 32GB San disk card.
I should note all my portable USB 3 hard drives work without issue on my computer so I do not think it a problem with my computer. I have only had this issue since I tried the Lexar 1000x 32GB card. Computer is Dell XPS 15 with Sandy Bridge.
I've sent a message to support, but won't get an answer for a few days.
Just a thought, have you tried plugging the camera directly to your PC? I purchased the new 1000x 128,64 & 32 CF cards and my USB2 port didn't see the files like yours so I ordered the new USB3, while I waited for delivery I would plug in directly to my computer to download, which worked.
My new reader worked out of the box. I run on a mac and there is no USB3 yet the reader works fine.
Could be your reader is bad.

I was going to try that next, but I cannot understand why my new USB 3 reader with the very latest firmware has an issue. I can understand the old USB 2 reader might have an issue.
I think my reader is faulty, but it's strange it can read a 32GB Sandisk Extreme card although only when plugged into a usb 2 port.

Does Nikon ViewNX2 see the files? It see the files on my Lexar 1000X cards and handles the transfer to my PC.
Free software if you are not using it to transfer files give it a try.
If I attach the reader to a USB port, the computer pops up a window saying do I want to download photos, but no software or file-manager can find any files. They all report the card as having no photos. I've tried LR, explorer, downloader pro. I though the reader had actually deleted my photos, but I went and put the card back in my 5D III and they were still there.
What I find bizarre is that the folders can be seen on the card - DCIM/100EOS5D, but they appear empty.

you say that all your usb3 ports are operative. is that at usb3 speeds and they recognize all your usb3 devices as such?
do you have a friend with any good readers that you can try it with. it should not matter as long as it is modern and preferred udma type?
is your sandisk card readable in the usb3 reader?
are you using the original USB3 cable? i had issues with some 3rd party cables as they were supposedly USB3 and would only perform at USB2. there is a difference in qualities unfortunately.
in the mean time download the images if you can from the camera and do a full erase and format in the camera.
I have the same reader and it works with my new Lexar UDMA 7 card.
For me it's rather obvious that the Lexar card reader will work with their own cards
Update. I managed to transfer the files successfully via the camera and EOS Utility.
I had installed the latest USB3 host driver from Dell a few weeks ago. I might try the old driver as the new describes an issue I've never had.
I was using the Lexar OEM cable with my USB3 reader. I don't have a another USB 3 cable to try anyway.
I downloaded files from my Sandisk 32GB in the new reader, but I think it only worked when I plugged it into the USB2 port. My old USB2 reader worked with my Sandisk in USB3 or USB2 ports.
I've just reformatted my Lexar card in the camera and will take a few photos and try again.

have you used you usb3 ports for anything else that is usb3?
Yes I have two native 1-1.5TB USB3 external hard drives that work fine and get up to 100MB/s transfer speeds, I have used several USB2 thumb drives that work fine and get 25-30MB/s.
I haven't tried my new card reader and 32GB lexar CF card combo in my PC yet, but that's only USB 2, not that worries me if it can actually read the files.
I still can't understand how I can see the directories on the CF card but not the files?
