windows build failed for me until manual vcpkg install

[anand jain]

i know the readme says that libusb will be downloaded and built. for my machine (win11), i needed to run vcpkg install libusb:x64-windows-static-md then the examples ran great.

here is the build failure i got trying to run the list_devices example before manually installing the correct libusb (vcpkg install libusb didn't work only the static one got it running)

thank you for the great library! this issue is very minor

Hmm.. this strange because in CI everything is ok https://github.com/a1ien/rusb/actions/runs/8860915455/job/24332216760
Can you try run
cargo run --example ffi_info --features=vendored -vv
and you can also try without --features=vendored
cargo run --example ffi_info -vv

[Ilya Averyanov]

Oh. you probably forgot to get git sub-modules
git submodule update --init
