The reset did not happen.
Exchange with TC on twitter - they think the unit needs more than 300 mA even though it says right on the unit that it expects 300 mA. They recommend I use the wall wart that came with it, but alas that wall wart is at home in Oakland and I am in LA heading for Arizona.
I guess I’m gonna stop at a music store in Pasadena and buy a new TC wall wart. Hope it works!
Than you for the advice, groupmind…
