Using drivers that are included in OS X, the ASM1142 USB cards doesn't work at all in El Cap. They work as a USB-3.0-only card in Yosemite 10.10.3 and newer.

So unless they have written their own drivers, I am suspicious of their claim for compatibility with OS X 10.6 and newer, and I wouldn't expect this card to work except as described above. The dodocool website has no drivers available for download, so where would you get drivers for newer operating systems?

My guess is that this is just an OEM ASM1142 card using OEM drivers with a dodocool logo slapped onto the slot cover.

I would welcome someone getting it to confirm one way or another, but if so, I'd order it from a place with a great return policy in case it fails to stand up to its claims.

[doublepost=1472089219][/doublepost]Hey guys,
I just tested a USB 3.1 pcie card with ASMEDIA chipset on 10.12 Sierra beta and ...

Woks Perfect, even from Disk Utility at boot screen!!!
I will test booting from the card.

I don't think you'll be able to boot directly from that card. The drivers that support the card aren't loaded until the OS has loaded.

BTW, ASM1142 cards work since 1st macOS beta.

Can either one of you test to ensure you are getting 3.0 or 3.1 speeds on the USB-C port?

Also can you verify if you are getting faster charging over the USB-C port?

Now that I actually have a USB-C device, I am curious if all this is working now or if it is still gimped/blocked as it has been in the past.

EDIT:
Dammit, every single card I can find with this chipset has supplemental power connectors on the back. I am NOT going back to Frankenstein y-cables to power a USB card. Been there, done that.

The PCIe slot is capable of 75W. How on earth do you need more than 75W for two USB connectors? Even if you have both ports outputting 5V/3A, that's only 30 watts.

[doublepost=1476412650][/doublepost]Not 100% sure here, but seems like USB 3.1 Gen 2 spec calls for up to 100W per PORT.

Doubt 99.999999% of USB devices will ever request that much power, even for charging. In context, my iPad Pro doesn't charge any faster on my USB C port of my Skylake PC. It does from a wall charger though. So the way an OS negotiates connections means everything.

Perhaps that is the maximum allowable spec in general, but these cards don't get anywhere near that. The highest I've seen any of these cards claim is 5V/3A, and even that explicity requires the supplemental power to be connected. Note the second sentence:

I can't find the 3A example right now, but this 2A example is even more ridiculous. 5V/2A would be 10 watts. For both ports, 20 watts. Why isn't the 75watt PCIe slot sufficient?

In any case, supplemental power or not, I mostly just want to know if anyone is seeing anything beyond USB 3.0 transfer speed or charging speed on these USB 3.1 cards yet.

It would be cool if there was a simple device that had little more than a numeric LCD display and a USB interface + cable. It could pretend to be a USB storage drive. The user would plug it into a computer and drop a file onto it. Then, the numeric display would show the write bandwidth it was pulling (the actual data would not be written onto anything, just discarded).

Can you click on USB on the left pane and then show us the Device Tree on the right pane. Then choose the USB Bus belonging to the card so that we can see which Host Controller Driver it is using.

Although it says the speed is 5Gb/sec, wouldn't that max out at 625mb/s, which the raid exceeds? I'm assuming if I added more SSD's to the raid it would be faster than the ~750 I'm getting. Not sure though.

my ASUS card (see post #6 in this thread) at least shows up as "USB 3.1 BUS" in the system profiler (macOS Sierra 10.12.1 build 16B2657). unfortunately I still don't own any 10 Gb/s USB 3.1 devices to verify the bandwith...

There's nothing to verify I'm afraid. x2 card of any kind in PCIe 2.0 slot tops out at 1GB/s theoretical and 800MB/s practical. 10Gbit on 2.0 would be possible only with card equipped with one controller per port.
My ASUS USB-C + USB-A shows up as 3.1 in ASP with 5Gbit maximum bandwidth (due to bus config IMO).
ASM1142 specs show that the chip itself runs x2 on PCIe 2.0 and x1 on a 3.0

Some tests of early production samples, synthetics and real world seem to confirm all above:
