Hello heed and svol, it sure is great news that you have figured this out as I had the same problem and couldn't find the solution in the German forum. I'm glad I found your thread here, and tried another USB-port and it works perfectly now the recognicion was possible. Aquasuite did find my Aquaduct 360 XT at first but by searching for it manually it did and after a restart with the CD in my drive I also got the message that the device was installed correctly.
I have a Gigabyte GA-EX58-UD5 motherboard with 12 USB-ports
Lavalys Everest tells me I have 6 times USB1 controller Intel 82801JB ICH10 - USB Universal Host Controller, 2 times USB2 controller Intel 82801JB ICH10 - USB2 Enhanced Host Controller and 2 times a Generic hub. So it looks like Gigabyte does the same trick, although I don't see a separate controller, just the one from the chipset. I picked one of the pair that was the nearest to the PCI-slots and that worked, also three restarts later. To be safe I don't use the other slot of this pair.
Hmmmm, I was happy too soon. Although my Aquaduct is recognized at startup it looses connection after an hour or so. You can notice it at the Overview when the Flow is constant (because it isn't!). It's connection is restored when I let the Aquasuite search for it but that isn't always the case and then it is gone until I restart the next day, an ordinairy reboot is not good enough. I wonder if svol has no trouble at all now, I don't think so.
I also tried to install it on an XP-machine 32 bit but that didn't work either. I have to try it when it works on my Windows 7 PC, haven't done that yet. If that's so, I think the problem is in the Aquaduct itself.

After a lot of trouble shooting it looks to me that the combination Aquaduct 360 and the Southbridge (Intel ICH10R) on my motherbord don't get along too well. It's that Southbridge that controls the USB-ports. At start-up the Aqua-suite shows my Aquaduct well but soon after it shows no fresh data. I can tell by the Overview page when the Flow rate is stable, which isn't actually. When I'm fast enough I can restore the connection by clicking on "Find my USB-device" but once it is really gone it rarely comes back. So I had a PCI-card with 4 extra USB-slots and installed that in another PC (the one connected to my Aquaduct is quite full) and installed the software. Once I plug the USB-cable in one of those slots, there is no problem at all. I think there is some time-out problem between the Aquaduct and the Southbridge.
Maybe my next motherbord wll have another Southbridge and the problem might be solved, for now I have to find a free slot for the USB-card.
