Your Livescribe Echo 2 smartpen includes a USB cable. More specifically:
1st connector: USB-A (connects to all PCs)
2nd connector: USB-C (connects to Livescribe smartpen and other devices)
Length: Six inches.
This item is an EXTRA USB cable for your Echo-2 smartpen.
It measures 3ft in length.
It is technically identical to the cable you receive in the box, but it is simply longer and (we think) therefore more practical for many people.
This cable is NOT compatible with the original version of the Echo.
