Didn't work on Windows 7, but worked on Windows 2003 Server x86. How is
running devcon.exe from a bat file any different to running it directly?

Also, I still can't load the driver with the service control manager api,
and although I can test the driver on NT 5.2 installed via bat file that
calls devcon, I need to be able to load it dynamically in my application.
Also, I need Windows Vista and 7.

Thanks,

I think I may have an answer, I have copied the devcon line from the docs,
and in the docs it uses smart quotes. The bat file was created manually using
normal quotes. So that's why the bat file worked. If I type correct quotes in
the command line it works as well.

However I still have all the other problems (can't load the driver with the
SCM API, doesn't work on Windows 7, etc).

Thanks,

Have you set the administrative privileges to the devcon.exe into
windows 7? About how to load the driver the source code of devcon
program are in the DDK, you can study it for understand how this
software is able to load the driver.

Yes, I am running as admin and I have disabled UAC. I checked the logs, and
with that information I was able to load the driver on Windows 7. On 2003, I
was able to install the driver with the inf file and the sys file in the same
directory, however, if I tried to do the same on Windows 7, it didn't work.
Fortunately, the logs were of great help.

I didn't know the source code for devcon was available. I can't find it in
the current WDK. Probably I'm not looking where I need to. The SCM API is
really simple, the problem with the fact that it doesn't work is that I don't
know what to check. Are there any logs I should look into?

Thanks,
