I'm running VirtualHere CloudHub on a RPi3 (version 3.5.8), along with the USB Console Client for Linux (amd64) on a Hyper-V hosted Ubuntu server. Everything works fine with client 4.4.6, but if I upgrade the client to 4.4.7 after a few minutes I get "cp210x ttyUSB0: cp210x_open - Unable to enable UART" in the syslog and the USB device does not work. For the time being I've just downgraded back to 4.4.6, but please let me know what additional information I can provide for troubleshooting going forward.
I made substantial changes between 4.4.6 and 4.4.7 , sounds like maybe a bug was introduced. I'll look at this ASAP. Can you tell me what version of ubuntu you are using? Could you email me the /var/log/syslog from the client when this issue occurs again. mail [at] virtualhere.com
