- If usbip client does not close a TCP/IP connection to a daemon gracefully, the daemon will keep this connection open indefinitely. - The issue is that the client cannot attach this device again until the device will be rebinded on server side by commands: usbip unbind -b X-Y usbip bind -b X-Y - usbip client enables tcp keepalive by calling usbip_net_set_keepalive from usbip_net_tcp_connect. usbip daemon now enables this socket option too for accepted connection.
