My first G400-TH module no appear in the Device Manager


I have connected a new G400 Th module by USB with the PC, unfortunately, it does not appear in the device manager, only controlled 5V-USB is on. Other FEZ Boards (G120) appear in the Device Manager.

Is the Board defective?

TH boards do not ship with power supplies. You need to add 3.3v.

Thanks, has just measured in the 3.3 volts Pin nothing lies close.

Again to thanks for the quick answer.
