Cabling and Connection
In order to comply with the specifications, the maximum length of USB 2.0 cables is limited to 5 m. Longer cables may be connected if you use high-quality material. For cameras of the USB uEye RE series, IDS offers cables with a length of up to 10 m (see also USB uEye RE Accessories).
The USB bus provides power supply with 5 V and 500 mA max. Many USB devices use the bus power and do not need external power supply (bus-powered devices).
