linux kernel<\/strong> for some time now, and a couple of solutions for both server and client are available on github, So here I will be investigating what I can do to bridge the Linux Raspberry PI to my windows PC,<\/p>\n\n\n\nUSBIP is a protocol where the server is the machine connected to the USB device via wire, and the client is the machine that needs to use the USB device but is not connected to it via USB.<\/p>\n\n\n\n
In linux, usbipd is the name of the server, and usbip being the client, In debian, both server and client are included in the usbip package, hence, on the raspberry PI and on the Linux server, we need to run the command<\/p>\n\n\n\n
apt install usbip usbutils<\/pre>\n\n\n\nThe modules of USB\/IP (usbip-core, usb-host, and vhci-hcd) are already included,<\/p>\n\n\n\n
We will get to the Windows client after the Linux to Linux section<\/p>\n\n\n\n
The two options<\/h2>\n\n\n\n
In the cases we are exploring here, the server is a Raspberry Pi (3), the client is a Windows machine, but there are a couple of things to try first, the Windows clients are KVM virtual machines, we will try<\/p>\n\n\n\n
1- The client is the Linux Host machine hosting the windows virtual machines, and the USB port is passed to the virtual machine<\/p>\n\n\n\n
OR<\/p>\n\n\n\n
2- The Windows client has the USBIP driver directly connecting to the Raspberry PI server <\/p>\n\n\n\n
The Steps<\/h2>\n\n\n\nOn Raspberry PI<\/h3>\n\n\n\n
Installing the USB\/IP server on the raspberry pi “apt-get install usbip”<\/p>\n\n\n\n
apt install usbip usbutils<\/pre>\n\n\n\nNow, let us assume i want to connect the following device to my debian machine so that i can leave it on a different desk<\/p>\n\n\n\n
lsusb
Bus 001 Device 005: ID 10c4:ea60 Silicon Labs CP210x UART Bridge<\/pre>\n\n\n\nLet us start by loading the requiered kernel modules<\/p>\n\n\n\n
sudo modprobe usbip-core
sudo modprobe usbip-host
echo -e \"usbip-core\\nusbip-host\" | sudo tee -a \/etc\/modules<\/pre>\n\n\n\nNow, we need to start the usbip deamon<\/p>\n\n\n\n
sudo usbipd -D<\/pre>\n\n\n\nNow, we need to list the devices all over again ! but through usbip<\/p>\n\n\n\n
usbip list -l
busid 1-1.5 (10c4:ea60)
Silicon Labs : CP210x UART Bridge (10c4:ea60)<\/pre>\n\n\n\nThe above is the relevant one, I chose to delete the other 3 (They come with every pi)<\/p>\n\n\n\n
Notice how we already have the data from the lsusb command `Bus 001 Device 005: ID 10c4:ea60 Silicon Labs CP210x UART Bridge`, but i have added this one too for completeness, and because the ids are easier to see<\/p>\n\n\n\n
Binding the Device: the device needs to be off limits to the pi itself, and proxiedthrough usbip, so we bind it with<\/p>\n\n\n\n
sudo usbip bind -b 1-1.5<\/pre>\n\n\n\nNotice how i copied the 1-1.5<\/code> from the usbip command<\/p>\n\n\n\nWe should also probably make it persistent by creating the file <\/p>\n\n\n\n
sudo nano \/lib\/systemd\/system\/usbipd.service
--------
[Unit]
Description=usbip host daemon
After=network.target
[Service]
Type=forking
ExecStart=\/usr\/sbin\/usbipd -D
[Install]
WantedBy=multi-user.target<\/pre>\n\n\n\nStart and enable !<\/p>\n\n\n\n
sudo systemctl daemon-reload
sudo systemctl enable usbipd.service
sudo systemctl start usbipd.service<\/pre>\n\n\n\nNow, you may be asking, how do we “Authenticate”, and the act of the matter is, we don’t, this is an unsecured<\/strong> thing, and if you want security, UFW is probably your friend<\/p>\n\n\n\nOn my Debian machine !<\/h3>\n\n\n\n
Let us connect this to my Debian machine<\/p>\n\n\n\n
First, the same package has the tools for both the server (PI) and the client (My PC)<\/p>\n\n\n\n
sudo apt install -y usbip<\/pre>\n\n\n\nNow, we need tools to create virtual USB devices, fake device driver so to speak<\/p>\n\n\n\n
sudo modprobe vhci-hcd
echo \"vhci-hcd\" | sudo tee -a \/etc\/modules<\/pre>\n\n\n\nNow, list remote devices<\/p>\n\n\n\n
usbip list -r 192.168.5.220
- 192.168.5.220
1-1.5: Silicon Labs : CP210x UART Bridge (10c4:ea60)
: \/sys\/devices\/platform\/soc\/3f980000.usb\/usb1\/1-1\/1-1.5
: (Defined at Interface level) (00\/00\/00)<\/pre>\n\n\n\nNow, all you need to do is attach the device<\/p>\n\n\n\n
sudo usbip attach -r 192.168.5.220 -b 1-1.5<\/pre>\n\n\n\nNow, to verify the connection<\/p>\n\n\n\n
usbip port
Imported USB devices
====================
Port 00: <Port in Use> at Full Speed(12Mbps)
Silicon Labs : CP210x UART Bridge (10c4:ea60)
3-1 -> usbip:\/\/192.168.5.220:3240\/1-1.5
-> remote bus\/dev 001\/005
<\/pre>\n\n\n\nNow, we are done with debian, but the truth of the matter is, we probably need this more for virtual windows machines ! in my case, the printer and scanner are the 2 things i need on windows, because of linux drivers problems !<\/p>\n\n\n\n
Now, to disconnect the above<\/p>\n\n\n\n
sudo usbip detach -p 00<\/pre>\n\n\n\nWindows<\/h2>\n\n\n\n
So let us dive into windows<\/p>\n\n\n\n
Install usbip-win2 (Get it here<\/a>)<\/p>\n\n\n\nNow use the GUI, that is what it is for<\/p>\n\n\n\n
If you insist on not doing that….<\/p>\n\n\n\n
usbip.exe list -r 192.168.5.220
usbip.exe attach -r 192.168.7.220 -b 3-2
# And to disconnect
usbip.exe detach -p 1<\/pre>\n\n\n\n<\/p>\n","protected":false},"excerpt":{"rendered":"
