KL27 connection via USB to KinetisFlashTool

We have a KL27 soldered onto a custom USB board.

 

The new KinetisFlashTool won't connect directly to this chip via USB-HID, even though it shows up properly in the Device Manager as an HID device with the correct VID and PID values.

 

Is the bootloader that ships inside each device supposed to connect to the KinetisFlashTool?

 

Is there some trick to get it to connect the first time?

We got this working by trying different WIN 7 machines until it started working with one.

The DOS command line tool BLHOST has worked on every PC.

The Windows GUI tools works only on random PCs I've tried. :-(

There is something that the tool is assuming is present, perhaps a compiler DLL, that when is missing the tool does nothing.

No error, acts like it was never even started.
