Thanks for the thought, but I don't want to be in that business at all. However, I do have three cards that I bought for testing; all of them work, and I only need one. I'll send you a PM.
Hi! I just followed your process and, Ta Ta!, my 4TB USB Seagate was recognized. THEN, I tried transferring a 100GB file. All went well for a bit, then stopped. I shut down, reset the power connector into the pciexpress card, restarted and the same thing repeated; fast transfer for a few seconds, then zero. Got any ideas? Thanks.I didn't think I needed to power the 2-port version either, but I had to. The MP recognized the card upon bootup, but disabled the card with a message about how a USB device was using too much power so it shut the card down.
I too have all bays full, both HDD and optical. Nevertheless, I used a y-cable in the optical bay to get power. You can indeed run power there through the tightly integrated case. See this post. I can provide pictures if it helps.
This is the particular card I used.
Everything is powered now and works perfectly with native drivers, which was the whole point. I didn't really want to hook up extra power, but now that I have, I can confidently use a bus-powered device if need be.
Here are the cables I used:
1) This one splits the SATA combo plug into separate data and multiple power plugs, including molex. It sits in the optical bay.
2) This cable runs from inside the optical bay to the card.
You have to temporarily remove one Molex connector from that second cable to thread it into the optical bay. I used the same route as the default SATA cabling.
Is Mountain Lion up to date? How are the source and destination drives formatted? Which exact model card did you get?
When I Google "4tb os x" I see lots of complaints about Disk Utility not formatting it properly or OS X not recognizing all of the capacity. Did it format fine and do you see all of the advertised space?
Try a bunch of things to see where issues occur and where they do not; this can help to identify the source of the problem. Try a USB 2.0 port just to see what happens. Try a different computer, or Windows if you have it. Try a different port on the card and a different PCIe slot on the MP. Try a different drive. Try copying other files.
Thanks for your thoughts. Yes, I have been checking the sys report. The Seagate 4TB does connect through the superspeed bus, when it shows up. The problem has not been failure to connect; it is that the drive disconnects (unresponsive) after a few minutes of data transfer. This is followed by the usual "you didn't disconnect properly" message. This is followed by the sys report still seeing the superspeed bus, but the drive is gone.
I left the MP on overnight and this morning the 4TB drive was still connected through the front USB 2 port. I ejected it and connected to the back, problematic USB 3 port (left port when looking at the back of the computer). No connection. After restart, there it was; connected to the superspeed port.
I'm beginning to think the card may be bad. I'm going to leave the drive connected for a few hours without any activity to see if the drive disappears. If it stays connected in the idle state that'll be interesting.

So after three hours of being connected but in active, the drive is still connected to theUSB3.0 port. I can play an individual video within. Of course the sys report still shows the drive connected. Next, tried to transfer a 200 GB iphoto file to this drive. Peak transfer rate was 112 MB/sec in the first 15 seconds, then 1 MB for a minute, now zero. sys report still brings up superspeed and the drive. Opening the drive shows folders, but files don't appear, so there isn't any communication. Same old same old.
Looking for ideas... I'm going to try another brand USB 3 drive
ActionableMango, I did as you recommended and disassembled the Molex connector to route the harness. On reassembly I got the red and yellow correct and "assumed" the indistinguishable black wires are interchangeable. Is this a bad assumption?
This morning I purchased a WD Passport 2TB and connected it to the USB 3 card. Same behavior as with the Seagate, so I conclude it is not the drives. I switched the black wires on the Molex connector and put the seagate back on the USB card. Same problem. It is time to buy another card and hope something changes.
Thanks everyone for your help. It has all been valuable. Keep you posted if the card works.
I was hoping someone would have figured this out by now... So I'll share:
Considering the fresco-logic chipset based cards:
1) Hook up your USB 3.0 device to the card.
2) apple menu -> about this mac - system report -> USB
3) look for USB 3.0 superspeed bus. Is your device on that bus or 3.0 High speed bus?
4) If you are not on the superspeed bus, unplug the USB device from the current port and plug it into the next. I've found the top port to works without issue as superspeed: 500MB SEC Read/Write to a SSD on the 2 port and 4 port cards. The card specifications states the FL1009 should have 2 SS ports, however the drivers on the MacPro don't seem to agree.
Also - Make sure your peripheral is a USB 3.0 Superspeed rated device. If it's not, it's slow and crippled. With the proper hardware, you should be getting the same speed over USB3.0 as you would over SATA3 on a velocity X2. (I have both)
Note: This took about 2 minutes to troubleshoot when the card showed up a month ago. Always check the system report to know what's up with your IO.
Enjoy
