Expand description

Abstraction over a claimed USB device for bulk endpoint I/O.

Implementations must be safe to share across threads. The control and stream channels use different endpoints, so a single UsbTransfer can serve both concurrently (with internal synchronization if needed).

Required Methods§

Source

fn bulk_write( &self, endpoint: u8, data: &[u8], timeout: Duration, ) -> Result<usize, U3vError>

Write data to the bulk OUT endpoint. Returns bytes written.

Source

fn bulk_read( &self, endpoint: u8, buf: &mut [u8], timeout: Duration, ) -> Result<usize, U3vError>

Read up to buf.len() bytes from the bulk IN endpoint. Returns the number of bytes actually read.
