impl<'b> Transport<'b> for USBTransport

fn tokens<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<Self::Token>, WebauthnCError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Available on crate features ctap2 only.

Gets a list of attached USB HID FIDO tokens.

Any un-openable devices will be silently ignored.

Platform-specific issues

Linux

systemd (udev) v252 and later automatically tag USB HID FIDO tokens and set permissions based on the f1d0 usage page, which should work with any FIDO-compliant token.

Previously, most distributions used a fixed list of device IDs, which can be a problem for new or esoteric tokens.

Windows

On Windows 10 build 1903 or later, this will not return any devices unless the program is run as Administrator.
