System can detect FPGA with PCIe add on card,but information is not correct.

Hello,

     I design a pcie add on card with x1  interface .  I design it by xilinx PCIe IP  2.4 .  The pc can detect a set with Intel' VID, not  xilinx's  VID : 

softwares- Xilinx ISE 14.7

IP core version: 2.4 

system- Win 10 home-64 bit, i5,single lane PCIe

I  have  check the followings ,

1)check the pin assignments ,especially   PCIe Reset Signal,  They are ok!

2) It takes processor more than a miniute  to configurate fpga , so I  add  a warm reset after  configuration   

3)  I make a driver by windriver, The driver is modified  with  xilinx VID  instead of Intel's VID ,  with  xilinx  DID  instead of Intel  DID,However the os forbids  the driver update.

So what can be reason here? And  What  can  I  do ?

Thanks!

Regards.

A good news is coming , the card can be detect in pc. I had no intention of changing the class code  of Pcie IP. The class code is defalult to set. The card detection is ok!
