1、don't update 10.0.1 from the lower version,if you do this delete de VM ,then reinstall it from the 10.0.1 dmg file；
2、start the vm with win10/win7 template or mirror image；
3、in the top status bar,click usb log, the choose connect apple ibrige,then you can find you usb device
all is my personal experience, hope it useful to you.
