I'm having trouble finding my Tessel on both USB and Wifi. I set it up without a problem at home then I brought my computer in to work and tried to reconnect to it, but I get a "WARN No Tessels Found." error. I understand that it probably wouldn't work with Wifi since it is a new Network here at work, but it does not recognize it through USB either. Is there a way to reset the Tessel and start from scratch to see if this would help?
