The SBT provides the standard 5V USB voltage so there is no problem here. I think you have a misunderstanding of current, the LOAD (your DAC in this case) determines the amount of current that flows over the connection. The source cannot "force" more current into it than it wants to take. The SBT will supply up to 500mA and your DAC takes less than 500mA so all is fine. If your DAC took more than 500mA THEN you would have a problem, but since the DAC takes less than 500 and the SBT can supply up to 500 all is good. EDO works best if the DAC is plugged in and powered up before the SBT is plugged in to a power source. There is no harm if it is not, it just might not connect properly to the SBT. There is no harm to anything by just unplugging the USB DAC anytime you want. If you want to switch to a different output of the SBT (say S/PDIF or analog) it is best to do so while the USB DAC is still connected. If you unplug the USB DAC THEN try and switch to a different output, the SBT is going to be complaining about not being connected to the USB DAC. It's best to switch first, that way you don't have to worry about the SBT trying to connect to a DAC that isn't there.
