Let me start with telling that i'm a very happy user of Windows 7. Windows Vista and WinXP wouldn't work (properly) on my laptop, not even the pre-installed version.
But there is one problem remaining: when i shut down or restart Windows 7 with the USB hub plugged in, i get a Blue Screen Of Death. Even when there is nothing plugged in, in the hub.
It's a 4-port hub
from Digitus. It's working ok. It's just causing crashes when shutting down.
