[dependencies]
labelo_p710bt = { version = "0.1.0", default-features = false, features = ["usb"] }
default = usb

The usb feature is set by default whenever labelo_p710bt is added without default-features = false somewhere in the dependency tree.

usb default = rusb

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
