Problem (Re)installing Particle Workbench

I’m in the process of upgrading computers, and while I’ve installed Particle Workbench, I seem to be missing some pieces. I tried flashing a program and got this error:

dyld: Library not loaded: /usr/local/opt/libusb/lib/libusb-1.0.0.dylib
Referenced from: /Users/me/.particle/toolchains/buildtools/1.1.0/dfu-suffix
Reason: image not found

I don’t seem to even have /usr/local/opt on this machine, let alone libusb installed it.

I could copy it from my old computer, but I’m wondering what I (or the Particle Workbench installer) did wrong that caused it to be missing from my new one.

Is this Linux or OS X?

Good point. macOS (Catalina).

Update: Based on this discussion, I installed libusb and now all is well.
