Hopefully you don't experience the same problem I am experiencing with Mcintosh / Eversolo.
Unfortunately you may not have USB until / if they sort that out with McIntosh DACs
Eversolo is not as big as they seem. Yes they are selling a bunch but when a dealer tells me he has 40 plus units that are bricked and need to be sent back to China for refurb, that is is a bad sign.
I would recommend going into set up immediately and turn off Auto Update. If you are lucky your build will have ver 1.2.50 firmware. Anything high may not recognize USB
Support is pretty bad with Zidoo / Eversolo.
