Got my 1st unit today - Um a noddy question, but what kind of USB cable do Ineed?

As it a wet week, I've done some updates to my pages and manual - it's a collection of information from the forums which may be helpful to new/prospective AM users. If you see any errors, feel free to let me know. https://sites.google.com/view/audiomoth/home

New data cable, reformatted card, computer recognises connection, configuration okay. Followed initial setup several times. Will NOT record in either custom or default settings. Now what??
