Starting a new thread here ... I've got a ADF4350EB1Z evaluation board with version 2.7 of the software running on a 32-bit Windows 7 OS (which is running from VirtualBox on an Ubuntu host. I've tried both USB power and external DC power (with corresponding switches) but the software always says NO USB. I've hooked up RFOUT to a spec. analyzer and confirmed that there is no output either. What could cause the NO USB connection?
