There has been some talk about a ONLY key pro being developer or in the possible future. This feature request work be for that possible future. One of the possible feature of the pro is have seen in the forms would be a mass storage option (secure flash drive). I would like to have it so that I can prevent or disable the flash-drive option via a firmware or option. In this way when the device is plugged in it would not present the flash-drive in the options.
Rational:
The current only key I have present itself as a hid keyboard/ security hardware, which allow me to use it at work. But my job has a strict no flash drive option on corp computers policy. I would not be able to use the pro version, if it presented a flash drive.
