Firmware Update

I received feedback from a user that if UsbSafe² is connected to a juice jacking unit that also can toggle the USB power it will actually reset the privacy mode and allowing Juice Jacking.

Due to this scenario I will update the firmware. When privacy mode is enabled by a user it will no longer be reset by removing and inserting the dongle to a USB port. You as the user will need to actively disable privacy mode by long button-press at insertion!
