Opened an issue, #13351818507, and was directed here.
I'm running VMware Fusion Tech Preview 2013 (build 1140310) and when I connect my fitbit USB device to the host computer, VMWare immediately crashes. If I attempt to restart with it still connected, it will crash again. If I remove the device and restart, VMware will start back up. VMware 5.0.3 - 1040386 works fine with the fitbit device connected.
Crash information is attached.
