Logging to USB memory

How can I use the “Logging to external USB memory” feature in EMU PRO?

To utilize this feature, you’ll require a USB stick and a USB cable. Follow the instructions in the manual to connect the +5V, ground, data+, and data- wires after cutting the cable.

Is it possible to establish communication with EMU PRO software on a laptop in a similar manner?

No, you need CAN interface.
