Hi Erel - it does fix the problem - and I think it would be the likely cause for anyone else getting the double log entry problem.
I had to use the bridge until around lunch time yesterday when I finally got the Intel Android USB driver working for my HUDL 2. I guess I just didn't shut the bridge down properly at both ends.
For anyone else experiencing HUDL 2 USB debugging problems - (1) Download and install the INTEL Android USB driver
https://software.intel.com/en-us/android/articles/intel-usb-driver-for-android-devices (2) On the USB connection options on the HUDL 2, un-tick BOTH boxes. USB debugging should then work. (Don't forget to enable it under developer options!!).
Ps. B4A is superb - I can't understand why Google haven't bought it off you. It knocks spots off their clunky development environment. Android development has gone from nightmare to great with this product. Debugging is so much faster. Very well done!!
