At this point you can either connect the AC adapter to the DC IN socket on the
oscilloscope or choose to use USB power. If you connect the AC adapter, the dialog

There are two ways to connect the scope to use USB power:
Use the double-headed USB cable supplied to connect to two USB ports on your
computer or USB hub. Any powered USB port that meets the USB 2.0 specification
is suitable. An unpowered USB hub cannot be used.
Use the standard USB cable cable supplied to connect to one USB port on your
computer. This USB port must be capable of supplying 1000 mA. The USB ports on
most desktop and full-sized laptop computers are suitable. If in doubt, consult the
computer manufacturer's technical specifications.
PicoScope will explain these requirements:

Either switch to a USB port capable of supplying enough current, use the double-
headed USB cable, or plug in the AC adapter.
