Re: Generating inf file for multiple devices.

Thank you very much for the explanation. I don't know whether I did in the
correct way but I made the INF file such that it can be used to install
both the devices.

I did as follows,

[Strings]
DeviceName1 = "Device1"
DeviceName2 = "Device2"
DeviceName3 = "Device3"
...
DeviceID1   = "VID_xxxx&PID_0009"
DeviceID2   = "VID_xxxx&PID_000B"
DeviceID3   = "VID_xxxx&PID_000C"

...
...

[LUsbK_DeviceGroup]
%DeviceName1%=LUsbK_Device, USB\%DeviceID1%
%DeviceName2%=LUsbK_Device, USB\%DeviceID2%
%DeviceName3%=LUsbK_Device, USB\%DeviceID3%

; For XP and later
[LUsbK_DeviceGroup.NTX86]
%DeviceName1%=LUsbK_Device, USB\%DeviceID1%
%DeviceName2%=LUsbK_Device, USB\%DeviceID2%
%DeviceName3%=LUsbK_Device, USB\%DeviceID3%

[LUsbK_DeviceGroup.NTAMD64]
%DeviceName1%=LUsbK_Device, USB\%DeviceID1%
%DeviceName2%=LUsbK_Device, USB\%DeviceID2%
%DeviceName3%=LUsbK_Device, USB\%DeviceID3%

Then I ran the 'dpscat' application and generated the CAT file. I think it
does self signing too. (Which I still cannot understand)

Then I installed the driver. It is working for now. But is this the correct
approach?

This method looks easy, ​I prefer a single INF file.​

Just curious, apart from signing what other tasks does the installer carry
out?

​I'm going through this http://www.osronline.com/showthread.cfm?link=223734​
really long thread to understand the signing process also. I'm trying to
figure out how the certificate trust chain is linked. It should link with
some trusted certificate and from where does that come from is a mystery to
me.
