I have a Tessel 2 and have followed the instructions on Windows installation. I'm using WIndows 7 and I've tried both 5.10.1 and 4.4.3 of node.js, but in both cases when I try "t2 list", I get the following:
INFO Searching for nearby Tessels...
WARN Detected a Tessel that may be booting.
WARN No Tessels Found.
Please let me know if you have any suggestions.
