Report.sh does not work for me either:

lasse@backend:~$ sudo ./report.sh good
Failed to find any device with vendor ID 10ec
lasse@backend:~$

yet:
lasse@backend:~$ lspci -nn|grep 10ec
02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 02)

I get this error several times a day, since I'm running a mythtv backend with heavy traffic:
