After upgrading to Windows Vista there are some series of unknown devices which are listed in Device Manager. Those are related to some PCI Bus 1, Device 7 function 1. I do not understand about it. What are they. I am not having any additional hardware connected to my system except a usb hub. I had never seen this on Windows XP. I tried to update the drivers through Windows Update but nothing was found. While I had checked properly everything in my system. Everything is working.
