Hello Pete,

I see. 


Is there any way I (or someone) could be involved/help implememting the other 
drivers (like libusb0.sys)? If yes, is there any information regarding on 
what/how to contribute?
I would be interested to help adding support for the libusb0.sys, because on a 
project I work now I need to be able to access the iPad without iTunes (and all 
services/drivers it provides), and libusbx is the only change to get it working 
:)


Thanks,
Timo

Please see 
http://sourceforge.net/apps/mediawiki/libusbx/index.php?title=Windows#Known_Restrictions:
"WinUSB cannot be used to set a device configuration that is different 
from the default one."

This is a limitation of Microsoft's WinUSB driver, as documented at
http://msdn.microsoft.com/en-us/library/windows/hardware/ff537060%28v=vs.85%29.aspx:
"WinUSB supports only the first configuration."

Note that we are in the process to integrate support for other drivers 
than WinUSB, that shouldn't have such a limitations.

There was a patch submitted recently to at least allow the sending of 
the set configuration request even when using WinUSB, in case there was 
some use on the device side for such a message. We plan to look into 
adding such a feature when we add support for the other drivers.
