Restarting USB and NAA

[AllenB]

NAA disconnection from USB, best current solution?

Behavior also depends on the DAC. Some DACs like iFi iDSD Micro run the USB interface from USB power even while the DAC itself is powered down, so the DAC remains always visible. For these, there is no USB disconnection. While many other DACs power USB from the same PSU as the DAC itself and thus disappear from the USB bus when powered down…

Is that the case with the Uptone Regen, or the soon to be released Sonore microRendu ( which seems to have to same USB ‘regenerator’ as the Regen built in)? Provided they are permanently powered, but the DAC on the other side may ‘disconnect’?
