I think I'm misunderstanding. The device has a captive cable with a USB-A plug on the end (i.e. not a female receptacle on the device), doesn't it?

Edit: I understand. I'm used to devices with receptacles rather than captive cables. Any reason why you went that way?

I was going back and forth on this for a long time, but ultimately I decided that a cable entering the device looks sleeker than a plug that is plugged into a socket on the frame.

Also makes it easier to place it on the included stand.
