I have some problems with an audio driver. The hardware is a multifunction
board and, so far I have managed to install the other drivers but this one.
The following is an extract from the FBA log:

9:47:47 AM - [FBAAddDevInstanceId] MOST_BASE\MOSTCP\4&1BB41E6&0&0001
9:47:50 AM - [FBAAddDevInstanceId] MOST_BASE\MOSTSYNC\4&1BB41E6&0&0002

……..

and so on… Here I see all the support for sound being installed.

During the FBA stage, I get a notification that some files are missing for
my driver. I think the culprit should be Mr. Wdmaudio.inf or some other inf
file. I am positively sure that all the files required for my driver are
there (there are only 2 files an the inf).

My understanding is like this: My driver depends on ks.sys and wdmaud.sys.
And I should install it after these two. But I don’t know how to impose such
a dependency (for the FBA). Any suggestions?

Hi Yalos,

Does this and related articles help to your case?
http://msdn.microsoft.com/embedded/community/community/tips/xp/compo/default.aspx


Anyhow drivers are usually installed by FBA PnP at phase 3100 from inf files and their issues are logged in setupapi.log not in
FBA.log
What you mention here are usermode programs (services/filters, etc) and their registrations.

When creating your component you can set FBA phase at which most of registration will happen if nedded.

Best regards,
Slobodan
