Question : How can DPInst search all of the subdirectories under the working directory

Hello everybody,

I'm trying to directs DPInst to recursively search all of the subdirectories under the main working directory. This is my DPInst.xml :

<search>
  <subDirectory>*</subDirectory>
</search>

and this is what happens when I try to do :

dpinst /path "c:\driverbackup\xp" /c /q /se /f

INFO: option set : dumping log info to console
INFO: current working directory: 'C:\driverbackup\xp'
INFO : Running on path 'C:\driverbackup\xp'
INFO: DPinst.xml does not list the current UI language
INFO : USER UI Language is 0x410
INFO: Install option set : running in quiet mode. Suppressing Wizard and OS popups
INFO : Install option set : Suppressing EULA.
INFO : Install option set : Force install if driver is not better
ERROR : No driver package found
INFO : returning with code : 0x80000000

I don't know because it happens : there are a lot of subfolders containing drivers under the DPInst main working directory.
