I did indeed solve the problem on a different usb port, but the funny part is that i ran out of usb ports to try to fix the issue. I had to find a usb backplate add-on to fix the issue, and i've been lucky i had that lying about from an older pc. And yes, windows still needs a bit of tweaking for the best playback. There are options you need to configure, and you also need to stop windows shutting down usb hubs to save energy. I found my dacs popping and clicking after a 15 minutes pause ... turned out to be an energy saving option that is by default set to "on". Gah!
