Great, thanks. That helps. The next thing to figure out is whether or
not we're reaching the ftdi driver or not when we're failing to connect
these other ports. To do that, could you make sure that the USB device
is unplugged and then run:

dtrace -n 'fbt::usbser_attach:return{ trace(arg1); stack(); }'

After which, plug in the device.

Thanks,
Robert
