The USB connector can be used as an alternative method for connecting the NextMove ES to a
PC running Mint WorkBench. The NextMove ES is a self-powered, USB 1.1 (12 Mbps) compatible
device. If it is connected to a slower USB 1.0 host PC or hub, communication speed will be limited
to the USB 1.0 specification (1.5 Mbps). If it is connected to a faster USB 2.0 (480 Mbps) host
PC or hub, communication speed will remain at the USB 1.1 specification of the NextMove ES.
Ideally, the NextMove ES should be connected directly to a USB port on the host PC. If it is
connected to a hub shared by other USB devices, communication could be affected by the activity
of the other devices. A 2 m (6.5 ft) standard USB cable is supplied. The maximum recommended
cable length is 5 m (16.4 ft).
