请问怎么编写INF文件？

急！

找个例子看看，下面是个完整的inf文件：
[Version]
Signature=\"$CHICAGO$\"
Class=USB
provider=%PHILIPS%
LayoutFile=layout.inf

[Manufacturer]
%MfgName%=Philips

[Philips]
%USB\\VID_04CC&PID_0547.DeviceDesc%=D12TEST.Dev, USB\\VID_04CC&PID_0547

[PreCopySection]
HKR,,NoSetupUI,,1

[DestinationDirs]
D12TEST.Files.Ext = 10,System32\\Drivers
D12TEST.Files.Inf = 10,INF

[D12TEST.Dev]
CopyFiles=D12TEST.Files.Ext
AddReg=D12TEST.AddReg

[D12TEST.Dev.NT]
CopyFiles=D12TEST.Files.Ext
AddReg=D12TEST.AddReg

[D12TEST.Dev.NT.Services]
Addservice = D12TEST, 0x00000002, D12TEST.AddService

[D12TEST.AddService]
DisplayName    = %D12TEST.SvcDesc%
ServiceType    = 1                  ; SERVICE_KERNEL_DRIVER
StartType      = 2                  ; SERVICE_AUTO_START
ErrorControl   = 1                  ; SERVICE_ERROR_NORMAL
ServiceBinary  = %10%\\System32\\Drivers\\D12TEST.sys
LoadOrderGroup = Base

[D12TEST.AddReg]
HKR,,DevLoader,,*ntkern
HKR,,NTMPDriver,,D12TEST.sys
HKLM,\"System\\Currentcontrolset\\Services\\D12TEST\\Parameters\",\"MaximumTransferSize\",0x10001,65536
HKLM,\"System\\Currentcontrolset\\Services\\D12TEST\\Parameters\",\"DebugLevel\",0x10001,2


[D12TEST.Files.Ext]
D12TEST.sys


;---------------------------------------------------------------;

[Strings]
PHILIPS=\"Philips Semiconductors\"
MfgName=\"Philips\"
USB\\VID_04CC&PID_0547.DeviceDesc=\"Philips ISP1581 Board\"

请问怎么让系统找到我的设备呢？
请问VID和PID怎么填写呢？
我做的是USB口到并口的一条转换电缆，不知道驱动程序该怎么写。
