The features of USB 3.1 in scanners include the following:
1. High-speed transmission interface: USB 3.1 supports transmission speeds of up to 10Gbps, which makes it possible to transfer large amounts of data quickly, making it suitable for scanners that need to process large amounts of image data
2. Efficient data encoding: USB 3.1 uses 128b/132b encoding, compared to USB 3.0's 8b/10b encoding, which results in a lower transmission loss rate and higher transmission efficiency
3. Multi-tasking capability: USB 3.1 supports full-duplex transmission mode, which allows for simultaneous data transmission and reception, improving the scanner's multi-tasking capability.
4. Compatibility: USB 3.1 is fully backward compatible with USB 3.0 and USB 2.0, which means it can seamlessly replace older versions of USB interfaces without requiring major changes to existing devices
5. Interface Types: USB 3.1 has three interface types, Type-A, Type-B and Type-C, with the Type-C interface featuring forward and backward plugging for greater ease of use.
