Hi Alan Yes, have read about that now and certainly external build would definitely be quicker. However - GREAT NEWS!!! The update to 4.9.36+ seems to have done the trick :) See new dmesg...

Work when directly powered from it too. No need to plug into Windows laptop or System 1 first. I thought it was particularly interesting that it connected at full-speed when it was low-speed before (that you had identified as a bug, Alan). Delighted to finally have it working - thanks for your help. I had tried apt-get dist-upgrade previously but always ran into issues, at least this gave me a drive to try and work out a bit more why it wasn't working and it was clearly worth it to solve the dwc2 issue!
