Hello,
Marc, what do you mean by "HTT Hub" ? I tried a research but found nothing.
I have the same problem than Marteen. Full-integration Virus doesn't works with any of the DAW software I use (Cubase 8, Live 9 and Logic 10), and with any of my computers (iMac 27' end 2012 on Mavericks and Macbook Pro 13 end 2013 on Yosemite). There is no sound coming out, the BPM light is blinking very fast and the Virus's software constantly says "A sync error occurred…".
The only way to make it work was to plug it alone in a Belkin Thunderbolt hub. But I tried the same thing with a USB D-Link H-7 hub, and with this one the Virus doesn't seems connected to my computer.
