Questions about remote access and install USB devices.

I have a server running openindiana, it hosts virtualbox and several VMs on it.

My first question is if I can run openindiana desktop from my windows on same network, now I am using XWin server under cygwin-X, I can run GUI of VirtualBox etc. but can I have the openindiana desktop show on my windows, since I don't much about unix command.

Another question is how should I install USB devices, Windows has plug and play, when I plug in a USB device, Windows will install and show the device, but when I plug a USB device on openindiana, I don't see it reacts in anyway and I am not sure where I can make it install the new USB device, what I really want is a way to have the USB device show in a VM on VirtualBbox.

Thanks, please help
