Hi there, Anyone else have info on USB 3.1 PCIe cards for classic Mac Pro models? I've been checking regularly and have only found this Asus model for a single type C port (Nothing yet for any USB 3.1 type A port PCIe cards): http://www.asus.com/Motherboards/USB_31_TYPEC_CARD/ Definitely seems to require an Asus driver but I cannot tell if that's for basic functionality or if the driver is required merely to get the speed boost claimed on the Asus site. Another unknown with this Asus offering is the power delivery for the type C port; as I understand it there is only 75W coming off the PCIe connection directly, which is 25W less than the USB 3.1 Power Delivery spec's requirement of 100W (http://www.usb.org/developers/powerdelivery/). Lastly, it seems like the fabless company leading the way on USB 3.1 chipsets will again be ASMedia - more info here: http://www.asmedia.com.tw/eng/e_show_products.php?item=155&cate_index=154 Love to learn more about this topic since USB 3.1 will be the best available I/O option for classic Mac Pros (since we know that Thunderbolt is impossible on cMP). Many thanks in advance for any info here.
