For the initial "Alpha" and "Beta" testing of the SkyRadar units for ADS-B, I used the POWERED hubs listed below.
<I have multiple Sport SX units.>
Since the Sport units have only one USB port (NOT high current), and I wanted a way to have the ADS-B and Memory Stick plugged in at he same time, it was needed. Hopefully in the future, I will also be able to add Bluetooth to my Sport (please, please GRT
)
The powered hubs minimize current drain on the EFIS and provide 4 ports.
Each model has a connection for 12V ship's power.
Multiple StarTech units are in use by friends of mine and one of my friends is using the CNX unit.
Either should be fine. It is probably more a personal choice for mounting.
I think I got them both at Amazon for about $50 each.
