It doesn't install through the Downloads site either, just tried to make sure.

Is there any way for it to be made available through Diablo Extras? If it works on Diablo then it ought to be...

I know there are workarounds but I'm trying to keep things as simple as possible, people ought to be able to install this with one click just like other Diablo apps.

It would be quite nice to make this happen because a number of the most popular tutorials (keyboard, memory stick, HDD) depend on USB Control being easy to install. Once it's installed, it's really really easy to use USB accessories through a gender-bender.
