Can I use a USB 3.0 pen drive to make a Windows installation disk?

I am buying a new pen drive and was seeing whether to buy a USB 2.0 one or USB 3.0 one. I read somewhere that USB 3.0 pen drives can't be used to make a Windows installation disk (using that famous Windows 7 USB/DVD Download Tool) whether it is Windows 7, 8 or 8.1. I am hearing conflicting reports on this. Can anyone confirm this for me?

P. S. If someone can confirm this for OS X installations also, it would be great. All I know is it will work for Ubuntu because their help page mentions it.
