Is libusb used on macos? if so, how to statically link it?

[naps62]

I'm having trouble using this crate (or rather, ethers-rs ledger support which depends on summa-tx/coins, which depends on this)

I'm compiling a cross-platform binary (windows, linux, macos), and the macos binary fails to run because it is dynamically linked to libusb.

Now, I don't know much about USB itself. from studying this crate's code, my interpretation is that macos only uses libhidapi.a, and libusb is only used for linux & illumos.

so I'd guess the problem is that macos is unnecessarily linking to libusb.
It could also be that it does indeed use it, in which case I'd like to find a way to statically link it, which probably involves a chance in this crate

Would appreciate any pointers. happy to do the heavy lifting myself

Was investigating this further
seems to only happen when building through github actions

as can be seen here: https://github.com/naps62/test-macos-usb-ledger/actions/runs/6973993949

the artifact from that build is a binary that is dynamically linked against libusb.
running the same build on a local macos VM produces a different result (no linking to libusb)
