Question on deployment

Question

Hi, 

I've no rolled my sensor driver and sucessfully installed it using devcon. I fear, I'm not allowed to distribute devcon to a client machine in order to use it there for installation/deinstallation (?). For this I wanted to use DIFxAPI for installing, but this doesn't work either.

DIFxCmd.exe /i Test.inf

DIFxAPI Sample Program

INFO: Option "/i"

INFO: Input file "C:\SensorsDriver\Test.inf"

INFO: Flags 0x0 (0)

TEST: installing driver package.

LOG Event: 1, ENTER:  DriverPackageInstallW

LOG Event: 1, Installing INF file 'C:\SensorsDriver\Test.inf' (Plug and Play).

LOG Event: 1, Looking for Model Section [NTx86]...

LOG Event: 1, No matching devices found in INF "G:\Windows\System32\DriverStore\

FileRepository\Test.inf_x86_neutral_af4d3025189618dc\Test.

inf" on the Machine.

LOG Event: 1, No drivers installed. No devices found that match driver(s) contai

ned in 'G:\Windows\System32\DriverStore\FileRepository\Test.inf_x86_n

eutral_af4d3025189618dc\Test.inf'.

LOG Event: 1, RETURN: DriverPackageInstallW  (0xE000020B)

INFO: There aren't any live devnodes with the DeviceId contained in the INF.

It all ends up in E00000020B... Is it generally possible to use this API for driver installation?

Answer 1

Hi Neil,

DIFxAPI will only work if there is a physical device involved.

Devcon is actually a sample in the WDK which can be downloaded from http://www.microsoft.com/whdc/DevTools/WDK/WDKpkg.mspx if you haven't already. The sources for devcon can be found at <WDK-ROOT>\src\setup\devcon. For your purposes, you can recompile devcon, rename it appropriately and you can then distribute it for your deployment.

Thanks,
Prasanna

Answer 2

Yes, found the sources already in my local WDK copy :)

Cool. Many thanks.
