3 out of 10 being a bit of a dud is not a bad score
What i found in 10 as well, is that it seems that the USB driver is claiming an interupt differently? I also have a SSL Duende PCIe and since 10 i needed to do several reboots before it's properly initialized, never had that problem before. dunno if this is related, but the behaviour change was definately tied to installing 3.0,10
