Hi Jake,
It was nice meeting you today.
Justin will need to comment on the USB cable/power concerns/questions directly. He will be back in the shop on Friday.
We do have an option/upgrade for the BB60C that removes the need for the y-cable and adds an external power supply.
Are you running in a VM on your Mac? We don’t recommend running our products on Apple hardware or in VM’s. If possible, are you able to switch to a native Windows PC for running our device? It could help us rule out a few concerns if you are running stable on a native Windows PC.
Feel free to follow up with us directly. andrew and justin at signalhound dot com.
Regards,
Andrew
