This is a USB 2.0 Type-B to USB-A cable. It is 2 meters long. It can be used to connect peripherals such as scanners, printers, DJ controllers, MIDI keyboards, servers, fax machines, and hard drives with USB 2.0 B terminals to devices such as laptops and MacBook Pros with USB (Type-A) terminals. [Important Notes] Before purchasing this product, please note that the target side of this cable is USB 2.0 B, not USB 3.0 B. [High-Speed Data Transfer] Transfers data at a speed of up to 480 Mbps for USB-A devices. The USB Type-B cable is compliant with full-speed USB 1.1 (12 Mbps) and low-speed USB 1.0 (1.5 Mbps) (backward compatible). Compared to a WIFI connection, this USB B cable provides more stable data transfer and more efficient work. [Durability and Flexibility] By adopting corrosion-resistant gold-plated pins, an aluminum alloy + nylon braided cable + double-shielded structure, it has a durable structure that allows for long-term use and improves connection stability. In addition, the tin-copper conductor ensures excellent transmission performance. Thank you. ^ ^
