ASUS USB 3.1 PCI Card in Mac Pro running El Capitan ?

Hi there,

As the proud owner of a Mac ro 4,1 (upgraded to 5,1 and with 2 X Xeon Hexa-Core X5670 CPU's) I "suffer" from one limitation.

And that is the now old and really slow USB 2.0.

I would like to add a PCI USB 3.1 card and I've spotted the ASUS USB 3.1 PCI Card.

Of course, that card is given as compatible only with Windows...

But I have seen some reports from people claiming to have inserted this card into their Mac and having successfully used it with several devices.

It seems that these reports are under "Yosemite".

I was wondering if they are still good with El Capitan...

I inserted the card into the Mac.

It seems to be recognized by the Mac Pro.

Indeed looking at the System Infos, under "PCI" give "USB Extension card".

BUT :

- no USB stick I insert mounts ;

- no USB drive I hook up mounts ;

- my mouse doesn't even power up ;

- the keyboard doesn't function...

So I was wondering if :

- El Capitan has got rid of the earlier USB 3.1 support in Yosemite ?

- Or if my card can be defect in any way ?

- If this behavior can be due to the upgrades I performed (Mac 4,1 => 5,1 + 8-Core CPU => 12 Core CPU) ?

If anyone would be able to help me out, I'd be eternally grateful :-)

If needed, card can be sent back to seller...

Regards.

FRED

That card, which you say provides Windows support only, undoubtedly requires a Driver to function at all Mac OS X.

Under Apple's new rules for ElCapitan, kernel extension Drivers must be signed with a recognized developer certificate, or they are simply NOT LOADED.

This is a feature of Mac OS X 10.11 ElCapitan, and is well-documented.

My personal opinion: You did not do your homework before installing this card in that version of Mac OS X 10.11 ElCapitan. You caused your own problem, and the bad things you imply about Apple are rubbish.

The pictures of the Datoptic card only show Type-A sockets. The Datoptic card is apparently also only two PCIe lanes which limits its maximum speed.

There is now a card with a USB-C connector and official Mac support from CalDigit and this works for El Capitan as well. However only Sierra supports USB3.1 at 10Gbps El Capitan only sees it as USB3.0 and therefore 5Gbps this card is also four PCIe lanes so can fully support USB3.1 10Gbps speed.
