请教高手inf问题

我现在用cypress的FX2开发板，按照给的pdf做完.sys文件和.inf文件后，为什么当我安装时，不能进行重列举了？？
我的inf文件如下：
[Version]
Signature=\"$CHICAGO$\"
Class=USB
ClassGuid={36FC9E60-C465-11CF-8056-444553540000}
provider=%Cypress%
;LayoutFile=layout.inf

[Manufacturer]
%Cypress%=Cypress

[Cypress]


; This VID/PID is used by several of the EZ-USB development kit
; samples.  This device is bound to the general purpose driver.

%USB\\VID_04B4&PID_8613.DeviceDesc%=EZUSB.Dev, USB\\VID_04B4&PID_8613
%USB\\VID_0547&PID_1005.DeviceDesc%=EZUSB.Dev, USB\\VID_0547&PID_1005
