What is the maximum length for USB Data?

In short – 5m is a safe maximum length to avoid loss of data. However, USB 2.0 provides for an industry recognised maximum cable length of 5 meters for devices running at Hi-Speed (480 Mbit/s). This is because data has to be sent and received within a specified time limit but all devices and cables on the USB network cause delays. The longer the cable, the bigger the delay, so 5m is a safe maximum length to avoid loss of data. OE Electrics supplies cables for USB 2.0 at either 1.8m or 5m, which are designed to go straight into the back of a PC. The connecting lead from the device to our unit should be kept as short as possible to minimise any signal losses.
