Hi,
now that Melroy and Dave want to spend time in improving x2go it came to mind that we are still lacking a long-requested feature: USB forwarding. So apart from implementing unit tests and doing code refactoring this is a great chance to make yourself immortal ;-)

I actually looked at the USB-over-IP project's documentation a while ago, when a potential customer might have needed USB support. It seems, however, that their approach is unidirectional, unless you're using Linux on both ends. In other words, with what they offer, it's possible to share USB devices connected to a Linux box (i.e. remotely controlling a USB scanner, to save the file directly on your client), but not connected to a Windows or macOS box. So it wouldn't work for passing through client-side USB webcams to the host, for example.
If somebody proves me wrong here, I'd actually be happy about it. ;-)

Innnteresting.
However, before we implement USB support, wouldn't it be better to support generic additional port (and possibly socket?) forwarding in X2GoClient? USBIP could then hook into that code, and port forwarding is a feature request that pops up occasionally.
(Socket forwarding could help in getting SSH agent forwarding added to X2Go, I guess... unless newer libssh versions already support that by themselves?)

Annnddd.. the socket forwarding code should then use unix domain
socket on the server side (instead of localhost IP ports)... SSH 6.7
and upwards does support that.

Maybe this is just a feature proposal/improvement that needs a separate bug ticket.
Could somebody document all this somewhere?... That would be nice, right?
Best regards, Melroy van den Berg
