OS client, Raspberry pi server and arduino

I am trying to use virtualhere to program an arduino connected to Raspberry pi 3 using a mac client.
I can see the arduino in the client console, but not in the arduino IDE.
When using a windows client, everything works fine.
I'm using latest raspberry pi firmware, and macOS 10.12.1.

A second problem is, after I program the arduino via virtualhere (using windows client), I am unable to reconnect to it through the Raspberry pi.
Before I run the server, it is available on /dev/ttyUSB0. I tried disconnecting the client ('stop using device'), and stopping the server, but it does not reappear on the pi. Only rebooting helps.

Any ideas?

OK, I got it to work on my mac (reinstalled drivers).
I still got the second problem though: ttyUSB0 is gone once I run the server, and is not coming back..

Yes it will come back if you edit the config.ini on the server and add the line AutoAttachToKernel=1
