That is what I thought of initially. And I think I am _almost_ there.
The script works, after several hours of trial, errors and your and
Dan's advice, when I manually execute it via systemctl. Start and stop
works.
It still does not work during boot time, though:
Feb 08 17:34:53 amiga5000 usbip[1014]: usbip: error: tcp connect
Feb 08 17:34:53 amiga5000 systemd[1]: Starting usbip client service...

'exit-code'.
Feb 08 17:34:53 amiga5000 systemd[1]: Failed to start usbip client service.
I am almost sure I got the targets wrong. I _am_ actually using
Network-Manager. Here is my service file:
Unit]
Description=usbip client service
After=network-online.target
[Service]
Type=oneshot
ExecStart=/usr/sbin/usbip attach -r raspberrypi -b 1-1.4
RemainAfterExit=true
ExecStop=/usr/sbin/usbip detach -p 00
StandardOutput=journal
[Install]
WantedBy=multiuser.target

Yes, I need some more help in the context of using Network-Manager.
