"This accessory may not be supported" error when using 30-pin reader with adapter

When using a TSS-PK8 (30-pin reader) with a 30-ping to Lightning adapter, you might receive an error that "This accessory may not be supported".  This is assumed to be a problem with newer devices (e.g. iPhone 7, iPad Pro) and how much power the device requires to work.

In some cases, simply clicking "Dismiss" will allow you to use the reader with Sub Rosa.

If the reader will not be recognized, please contact the Support Department at
