I can confirm that escribe is working with Virtual Box running on mac OS X EL Capitan, I'm using a External display on my Mbp which has a 4 port usb hub. When the DNA 200 is connected to this the software connects & runs without issue. UPDATE!!! It's now working connected directly to the MBP, on the first try it failed so i disconnected & reconnected the battery in the mod, plugged it into the usb, it then successfully connected and worked.
