I use the VM_0.6 for the firmware change(my crazyflie is 1.0,and PC is win7 64bits ).
when I use the VirtualBox, the make cloud Progress is perfect and when I click the "flash by crazyradio", the computer couldn't find the crazyradio.Even if I had already choosen the crazyradio in the USB.

When I use the VMare Player, the make cloud Progress has a warning ,and when I click the "flash by crazyradio",the Flash progress finished and the crazyflie died, I turn on the switch ,only the LED blue lighted, the LED Green and Red are all in dark.

I have tried the VM_0.5 in both Virtual Machine,But I couldn't open either of them. The display is black.

And now, I even can't fly the crazyflie in PC,the client couldn't find the crazyflie.

Could anyone give me some suggestions?
Thank you~
