arduino & raspberry pi 2

Hello,

I am trying to use virtualhere to connect from my mac to an arduino due plugged into raspberry pi 2.

The server and client work great, I can see the arduino in the virtualhere client interface tree, and it is marked "in use by you". However, the arduino IDE does not seem to see it in the available ports list.

When I check the system usb info using ioreg -p IOUSB -w0 -l, I can see the arduino. When I check using the pySerial utility (serial.tools.list_ports) I can't see it.

When I connect a usb storage device, I am able to access it without problems.

Ideas will be appreciated,

Thank
