Re: Generating inf file for multiple devices.

A couple more things.

If all of these devices use libusbK/WinUSB then this becomes even easier 
to do.  There are 2 different techniques you can use for this.

Method #1
1) Open your .inf file and locate the "DeviceID" in the [Strings] 
section.  Remove this string.

2) Find all the places where the %DeviceID% token is used and replace it 
with ALL of your device IDs. IE:

; For Win2K
[LUsbK_DeviceGroup]
%DeviceName%=LUsbK_Device, USB\%DeviceID%

becomes:
; For Win2K
[LUsbK_DeviceGroup]
%DeviceName%=LUsbK_Device, USB\VID_FFFF&PID_0001, USB\VID_FFFF&PID_0002, 
USB\VID_FFFF&PID_0003

Method #2
The driver install tool is capable of installing multiple .INFs at once 
as if they were one.  You should only need to create an installer for 
each device then copy all of the .inf files into a single install folder.


In both cases be sure and run "re-pack-files.cmd".  This is a handy 
batch file that rebuilds the InstallDriver.exe for you.
