A fun fact:
USB connectors have the USB symbol molded into the TOP of the connector, except:
The 'tactile' indicator of the Amazon VV dongle (a dent) is on the BOTTOM of the connector.
So for you vision impaired and/or blind people reading this post -
Those who would position the indent under their thumb -
Remember to turn your Kindle face down to plug the dongle in.
Well done Lab126.
