Great question — answering as the UphillTech team:
To install USBIP 2.0 on 4.2.0-42-generic I had to find the source code to USBIP. It is not /usr/lib/linux-tools/. The source was to be found in the folder: linux-lts-wily-4.2.0 I found the source in this folder: linux-lts-wily-4.2.0/tools/usb/usbip Following the instructions in this link I was able to compile, install and run USBIP. Installing linux-tools-generic did not work. I had to compile from source. I can now connect to my Arduino on my Raspberry Py's USB port from my Ubuntu computer. Much faster than using XRDP and running Arduino IDE directly on the Raspberry Pi.
