I recently installed window 10 on my mid 2014 i mac ,the mac os is big sure ,I've noticed that if I plug a USB device when in window such as a USB pen or DVD drive or in my case a audio/midi interface will just stop working is if nothing is plugged in, example, I plugged a USB stick to download some photo and after few second the actual USB folder or logo disappeared from the screen, is bin happening often now ,but not in mac os .....any clue??
