So far, no problems. Unless that is my problem with the Nano. They power up nicely from the notebook USB and I have console in a terminal window. Though 'screen /dev/ttyUSB0 nnnn' requires root privledges. Being in Wheel group is not enough. I have also plugged a few of them into a USB hub, but it has to be powered for more than 2. Plus you never know which system is which numbered ttyUSBn.
