Yes that's right, couldn't find an older version of the USB interface for love nor money. But it seems like that's working with the two green lights but no recognition of the guitar being plugged in.
Don't worry, not going anywhere! :) Using a laptop too, have tried it on multiple laptops of different ages and operating systems as well, in case that made a difference but no luck. Think I might be the guitar as I've had it over 10 years and never tried it but who knows! Plus the chances of finding a tech guy to physically look at it were remote before lockdown, let alone now.
