Deploy USB-devices via Network as simple and stable as possible

Features:

• auto-export on host when a defined usb-device has been plugged
• auto-attachment on client when a disappeared remote-device is available, again.

Files Included:

README.md
usbip-export@.service
usbip-attach@.service

Package dependencies

• usbip
• lsusb (pre-installed on most distributions)

Installation

install the systemd-files as root.

usb-host:
install -m 644 -o root -g root -t /lib/systemd/system/ /your/filepath/usbip-export@.service

usb-client:
install -m 644 -o root -g root -t /lib/systemd/system/ /your/filepath/usbip-attach@.service

execute on both sides:
systemctl daemon-reload

Usage

To export a pysical usb-device you have to determine the vendor and product id of your device with lsusb the format is [idVendor]:[idProduct] like: 301b:56f1

Now, you're able to export/provide your usb-device.
Syntax:
usbip-export@[idVendor]:[idProduct].service e.g:
systemctl start usbip-export@301b:56f1

At last, you're able to attach the usb-device from the remote IP on a client.
Syntax:
usbip-attach@.service@[host]_[idVendor]:[idProduct].service e.g.:
systemctl start usbip-attach@192.168.0.10_301b:56f1

            /usr/sbin//usr/sbin/usbip attach --remote=$host --busid=$busid
        fi

    sleep 1

stopping:

    echo $i | grep -q $dev

    if [ $? -eq 0 ]; then
        port=$(echo $i | cut '-d ' -f2 | cut '-d:' -f1 | tr -d '[:space:]')
    fi

In the "usbip-attach@.service" both ExecStart and ExecStop look like cut of at the end.

I recreated it from the explanation part of you port:

For me on the usb-host I had to use those two cmds:

sudo modprobe usbip_core
sudo modprobe usbip_host

Only after this the service was able to bind the device.
The error before was like this:
usbip: error: failed to open /usr/share/hwdata//usb.ids
and
usbip: error: unable to bind device on 2-1.7

The relevant lines you've pointing to haven't been cut ...
here is my current running part:

ExecStart=/bin/sh -c "host=$(echo %i|cut '-d_' -f1|tr -d '[:space:]'); dev=$(echo %i|cut '-d_' -f2|tr -d '[:space:]'); while true; do lsusb | grep -q $dev; if [ $? -ne 0 ]; then busid=$(usbip list -p -r $host | grep $dev | cut '-d:' -f1 | xargs echo -n); usbip port|grep -q $dev; if [ $? -ne 0 ]; then /usr/sbin/usbip attach --remote=$host --busid=$busid; fi; fi; sleep 30; done &"

ExecStop=/bin/sh -c "dev=$(echo %i|cut '-d_' -f2|tr -d '[:space:]'); usbip port | while read i; do echo $i | grep -q $dev; if [ $? -eq 0 ]; then usbip detach --port=$port; fi; echo $i | grep -q Port; if [ $? -eq 0 ]; then port=$(echo $i | cut '-d ' -f2 | cut '-d:' -f1 | tr -d '[:space:]'); fi; done"

the only significant modification in ExecStart is setting sleep to 30s.
... and depending on distributions the installation path of executable binaries may vary ... therefore I changed absolute paths to dynamic.

Certainly, depending on your distri, kernel modules might be not loaded automatically by installation.
Refer your distribution how to load additional modules on boot.

Ubuntu and most other distries are using entries in /etc/modues
