Q: Extract the answer to the question from the following context. Question: What kind of devices are examples of this? Context: Some USB devices require more power than is permitted by the specifications for a single port. This is common for external hard and optical disc drives, and generally for devices with motors or lamps. Such devices can use an external power supply, which is allowed by the standard, or use a dual-input USB cable, one input of which is used for power and data transfer, the other solely for power, which makes the device a non-standard USB device. Some USB ports and external hubs can, in practice, supply more power to USB devices than required by the specification but a standard-compliant device may not depend on this.
A: external hard and optical disc drives

Q: Extract the answer to the question from the following context. Question: How did the Pleyel piano arrive to Chopin?
