Trying to flash TWRP to Note3 using Heimdall v1.4.1 on Ubuntu 16.04 LTS and I get the following:

Initialising connection... Detecting device... Claiming interface... Setting up interface...

Initialising protocol... ERROR: Protocol initialisation failed!

Releasing device interface...

and I get similar message using Heimdall front end gui and I try download PIT file from device. Phone is in download mode, and gui detects phone. What is going on? Anybody have any idea? Thanks in advance.
