They put out an update to the firmware 2.01 that enables 2048 resolution and is not recognized by Heli-X.
I'd like to see an update to allow this new firmware. Here is the info I saw in MacOS and Parallels 8
In eFlightworks
1.54 is seen as MHW Interface V4
2.01 is seen as MHW Interface V4 2048
In the USB device interface of Parallels 8
1.54 is seen as MHW USB Controller
2.01 is seen as MHW USB Controller 2048
Support for MHW Interface 2048 firmware update
