Problem solved.

I've updated fwextract.pl to recursively search all nested subdirectories.  
I've also updated the documentation so that this is mentioned, and I've 
included a warning about the fact that it will probably take a LONG time 
to extract the firmware if you accidentally (for example) specified "/" as 
the "windows directory" (however it will probably still find it if you 
wait long enough and have enough virtual memory)...

I've also modified fwextract.pl slightly so that the --driverDir option 
name can be dropped.  Just list the directory to scan on the command line.  
In fact, you can list multiple directories and they will all be scanned.  
The --driverDir option is still present to preserve old behavior and if 
nothing at all is specified then "win_driver" is still the default.

There's no new driver snapshot strictly needed for this, since you can 
grab fwextract.pl directly from the site using this link:

The next snapshot of course will include this.  As always, the main 
pvrusb2 web page can be found here:
