Solved with --> sudo apt-get install libusb-1.0-0-dev

@vipulgupta2048 were you building this on an x86 platform? We basically don't expect it to be built against x86 because you're never going to run against something that isn't a balenaFin and we package a pre-compiled binary for the uhubctl which shouldnt require libusb

[vipulgupta2048]

Yes. We have to consider the possibility of folks building/developing testbotsdk on x86. I couldn't do an NPM install for adding a new package to the package.json because of the preinstall step of installing uhubctl

[vipulgupta2048]

This is still an issue and comes up when installing Leviathan on x86 systems.

@vipulgupta2048 I'll open a PR to address this
