I'm having similar issues and posted a thread before I saw yours. I like to say this is a windows 10 issue but from my google searches I've seen it happens across 7 and 8 too. I got my controller to work but had to go through a convoluted mess to get it to work and have to start it up a special way to ensure no issues. I'll let you know if I find any info but so far I got nothing official.
