I connected Seagate 3GB desktop drives, 1TB and 500MB portable drives, and a USB 3.0 memory card reader, directly on the card and via a USB 3.0 hub, and everything is rock solid.

Unlike earlier el-cheapo cards I had used, which did not support USB 3.0 hubs and caused regular kernel panics (I never managed much more than a day of uptime, which is why I removed them), this one has been performing absolutely flawlessly. I installed it with Kext Utility 2.5.6 and after a reboot my card functioned perfectly. I read the Amazon reviews for this card and one user named "Jack" mentioned using the open source driver GenericUSBHXCI. Restarted, and the card was recognized, System Information reported "driver installed: yes" for the card, but it would not recognize disks when plugged in. Initially the system would not go through the boot sequence (stuck on the Apple logo), so I removed the card, restarted, and removed leftover extension kexts for previous cards which I had never got to work successfully (CalDigit I think).

Installed the Orico 4 port card in my 2010 Mac Pro running OSX 10.9. ***** Edit: This is on 10.6.8 Snow Leopard. Still though, the disk tested faster than an internal SATA Caviar green. And when I look under USB in System Profiler, the hard disk is identified under Superspeed USB as being capable of up to 480 Mb/s, which happens to be USB 2.0 speed. When looking in System Profiler, the "Link Speed" is only showing 2.5 GT/s, vice 5.0GT/s as someone else's screenshot showed. I also tested my internal Western Digital Caviar Green which only got about 42 MB/s speeds. My disk speed tests in AJA showed about 62 MB/s read / write using a 1.0 GB test file and Video Frame Size of NTSC DV25. I tested using a Western Digital WD4000KD in a Thermaltake BlacX 5G USB 3.0 adapter. Enjoy USB 3.0 on your Mac for less than half the price! Kext Helper will tell you to "Reboot and pray". Drag the PXHCD.kext from your Desktop into the Kext Helper window. Run the Lacie installer for your version of OSX Do NOT restart.ģ. Unzip the patched kext (named PXHCD.kext) to your DesktopĢ. I downloaded a patched kext to replace Lacie's (Lacie does a drive check & if it doesn't detect a Lacie drive, it won't work).ġ. I downloaded and installed Kext Helper here

I downloaded the Lacie drivers from their site I ordered the "Pluggable Superspeed USB PCI-E" card from Amazon for $25.95

Shame they charge such a "premium" for Mac drivers, but I digress. Thought I'd share my experiences trying to get USB 3.0 working on my 2008 Mac Pro without having to shell out ~$70.00 for a Sonnet Allegro or similar Mac-only USB 3.0 PCI-E card.
