Raspberry OS 12 Bookworm no longer allows SSH over USB-C (Ethernet gadget mode) #5737

Describe the bug

Raspberry OS 12 Bookworm no longer allows SSH over USB-C/Ethernet gadget mode.

Steps to reproduce the behaviour

Hi everyone!

Not sure if this was already reported or if this is the right place to bring this up. If that's not the case, please let me know and I'll close this issue :)

I have a Raspberry Pi 4B that I could connect to via SSH over USB-C with previous Raspberry OS versions by making the following configuration:

/boot/config.txt

# Adding next line to enable USB-C
dtoverlay=dwc2

/boot/cmdline.txt

# Some stuff...
rootwait modules-load=dwc2,g_ether g_ether.host_addr=aa:bb:cc:dd:ee:ff

Note: I made sure that there is only one space after rootwait and one space after my new configuration.

/etc/dhcpcd.conf

# Static IP Config
interface usb0
static ip_address=192.168.2.2
static routers=192.168.2.1

But that is not working anymore in Raspberry OS Bookworm. Unfortunately my previous micro SD card stopped working so I noticed this when installing a new one.

It would be great if that configuration can work again on the new Raspberry OS version, as it's super confortable and easy to use a single USB-C cable for both power and network communication with the board.

I'll appreciate any help on this. Thanks in advance!

dmesg | grep usb output

No mention at all of usb0 (sorry for not pasting logs, I'm writing this on a different machine than my Raspberry board).

Additional context

The configuration I shared worked fine with a previous Raspberry OS version but that's not the case anymore. I'll try and see if the Raspberry Pi Installer gives me the option to install a previous version to verify that my configuration is the right one and the issue is caused by the new Raspberry OS version.

Can you log in via SSH over another interface, e.g. WiFi or Ethernet?

cmitu · 2023-11-23T16:27:49Z

/etc/dhcpcd.conf

But Bookworm doesn't ship with dhcpcd anymore, it uses NetworkManager for the network interface configuration. One of the udev rules shipped with the the NM package is /lib/udev/rules.d/85-nm-unmanaged.rules, which shows:

...


# USB gadget device. Unmanage by default, since whatever created it
# might want to set it up itself (e.g. activate an ipv4.method=shared
# connection).
ENV{DEVTYPE}=="gadget", ENV{NM_UNMANAGED}="1"

This may indicate that NM doesn't configure/ignores the USB device (usb0).

Hi. Yes, if I connect my Raspberry Pi to the same WiFi connection I can both ping it and SSH into it.
I'm pretty sure something changed in this new version and Ethernet gadget mode over USB-C stopped working.

I'll play around that to see if I can enable it. It's a shame usb0 is not enabled by default like in previous OS versions, though. Thanks for the hint :)

Nahuel92 · 2023-11-24T22:32:14Z

I was able to make it work thanks to your hint. This is what I did to be able to use SSH over USB-C:

/boot/config.txt

# USB-C
dtoverlay=dwc2

/boot/cmdline.txt

rootwait modules-load=dwc2,g_ether

first_run.sh

Before the rm ... command, add this:

cat << EOF > /etc/network/interfaces.d/usb0
auto usb0
allow-hotplug usb0
iface usb0 inet static
    address 192.168.2.2
    netmask 255.255.255.0
    gateway 192.168.2.1
EOF

Note: This seems to be a hacky solution, though.

On Mac host, configure `RNDIS/Ethernet Gadget` as follows:

IPv4: Manually
IP Address: 192.168.2.1
Network Mask: 255.255.255.0
Router: Leave it empty.
DNS Servers: 8.8.8.8 or whatever you prefer

Can you please let me know what this first_run.sh is ? and "Before the rm ... command, add this:" as well ?
Thanks in advance.

Nahuel92 · 2024-01-03T13:23:14Z

Can you please let me know what this first_run.sh is ? and "Before the rm ... command, add this:" as well ? Thanks in advance.

Hi.

You'll find the first_run.sh script in the root directory of the micro-SD card immediately after installing Raspberry OS and before booting the OS for the first time (it will be automatically deleted after first boot).

And the rm... line is inside that script (it's the line that auto-removes the script after first OS boot).

Late to the game (here in Germany RPi 5 couldn't be bought by normal people up until few weeks ago).

To restore the former behaviour (activating dwc2/g_ether in config.txt/cmdline.txt ending up with the RPi being accessible via a proper – random but unique – link local address regardless of IPv4 or IPv6) all that would be needed (by the makers of the distro) is:

adding avahi-autoipd to list of already installed default packages
adding the file /etc/network/interfaces.d/usb0 with the contents below [1] to their OS images

usb0 remains unconfigured by Network Manager and if g_ether isn't loaded the /etc/network/interfaces.d/usb0 does no harm. But in case dwc2/g_ether are loaded avahi-autoipd simply does the job. RPi5 connected to an USB-C port of my Mac:

Of course the down case is pointless since once the link would go down power already is gone

@ThomasKaiser - thank you for writing that up - it REALLY makes it sound easy and simple and straightforward.

…unfortunately I couldn’t get it to work. At all.

Specifically the usb0 device never shows up and never is configured, despite following all of your steps.

My use case is to have the pi5 (as I’ve ALWAYS done with my pi4) be powered and providing ethernet to/from my iPad Pro. So I’m SSHing into the pi5 from my iPad Pro and yeah, I never get a usb0 device, despite having installed avahi-autoipd and adding your usb0 script. Note that I’d already had the relevant bits in my config.txt / cmdline.txt from earlier efforts…’’

Any advice to get this to actually work would be GREATLY appreciated! THANK YOU! :)

ThomasKaiser · 2024-02-16T00:06:34Z

Any advice to get this to actually work would be GREATLY appreciated

Well, my aim was to point @pelwell and colleagues into the right direction since it's really just installing avahi-autoipd and creating /etc/network/interfaces.d/usb0 with the aforementioned contents. No idea what went wrong in your installation but most probably it's a typo (and end users shouldn't need to care about anything related to this since the OS maintainers should take care)

pelwell · 2024-02-16T10:14:13Z

I found a similar thread with a similar conclusion on the forums: https://forums.raspberrypi.com/viewtopic.php?t=357938
Another thread (Thagrol again) focuses on the ZeroConf aspect: https://forums.raspberrypi.com/viewtopic.php?t=358527

@XECDesign What is the preferred method for getting link local IP addresses, now that we're using Network Manager? The nmcli options ipv4.method link-local ipv4.link-local enabled are the most obvious, but the lack of an automatic failover makes it painful.

Is it better to install dhcpcd instead?

verxion · 2024-02-16T11:31:34Z

Well, I installed dhcpcd. It didn't work either. I followed all the steps that worked on Pi4 and they don't work (for me) on Pi5...

ThomasKaiser · 2024-02-16T11:38:23Z

I've to admit that I haven't thought about dhcpcd at all

tk@rpi5:~ $ apt-cache show avahi-autoipd | grep ^Size
Size: 40788
tk@rpi5:~ $ apt-cache show dhcpcd | grep ^Size
Size: 11088

Unfortunately dhcpcd-base will be pulled in by dhcpcd as well and so we're well above 600K. Asides that this works too:

Since you seem to already suffer from no usb0 device being created every other step can only fail. If your iPad shows nothing connected via USB then there's nothing to fiddle around with dhcpd or something else. Check with dmesg | grep -E "dwc|usb" what's going on.

As a reference output from my box:

@verxion please let us stop here hijacking this issue with random support stuff that should go to the forum. I would try to remove the quiet splash string from your monstrous cmdline.txt, and if after another reboot still no usb0 device shows up and nothing wrt dwc2 1000480000.usb appears in dmesg output then open a thread in the support forum providing above info and output from lsmod command.

In case it works simply leave a 'thumbs up' here :)

verxion · 2024-02-16T20:42:20Z

Thanks ThomasKaiser, but that didn’t help. Could you please provide a link to whichever forum you want me to post on?

And if you watch closely your dmesg output cleaning up your cmdline.txt actually helped and you're one step further since now at least g_ether driver is loaded just resulting in another error couldn't find an available UDC (maybe related to dwc2 not being loaded so check with lsmod, modprobe and friends. At least you're far away from upper config layers like dhcpd since usb0 is still missing and testing this stuff with a vanilla Raspberry Pi OS install would be the way to go).

XECDesign · 2024-02-19T13:22:18Z

@XECDesign What is the preferred method for getting link local IP addresses, now that we're using Network Manager? The nmcli options ipv4.method link-local ipv4.link-local enabled are the most obvious, but the lack of an automatic failover makes it painful.

Sorry, I'm not sure about this one. I remember looking it up a while ago and seeing people say "yes, you can do this with those options" but no explanation how to get fallback working properly. I haven't tried to get it working myself, so I have no idea.

We used to patch dhcpcd a bit to make it work properly. Now it's just the stock Debian version, so I can't vouch for it.

garytorgersen · 2024-03-09T02:12:58Z

Forget g_ether. Change these:

modules-load=dwc2
Add libcomposite to the end of the /etc/modules file

You will need to do the configuration for libcomposite but you are already creating the network interface so should be simple.

verxion · 2024-03-14T09:51:03Z

I wasn’t ever able to use what I found here to get things working. I did my own write up. It works with a USB-C to USB-C cable between iPad and pi5. I’ve tried the steps multiple times with fresh micro SD cards - works consistently every single time.

Hopefully this will help some other people out there.

Forget USB-C, Raspberry OS 12 Bookworm renders the Raspberry Pi Zero completely unusable as that device does not have any other networking interface.

josafat-daysequerra · 2024-08-03T16:00:57Z

I used the guide posted by verxion and got the USB-C device to show up with the correct IP address, I can ping it, however when I try to connect I get the error "Connection Refused" obviously check sshd file and it's set up to listen on all interfaces. Anybody else had this issue?

EDIT: Found my problem I was using the wrong IP address (10.55.0.2 assigned to my machine) instead of the server (10.55.0.1 raspberry pi/router).

Forget USB-C, Raspberry OS 12 Bookworm renders the Raspberry Pi Zero completely unusable as that device does not have any other networking interface.

Hi For all those struggling with online guides and the Pi Zero W, use the legacy 32 bit Bullseye based OS and then they work as described. I don't know how @dimitrovs comment could be better publicised? I failed to configure the wifi properly (thought I had) so I expected I could modify the boot files. Now - days later - I have access via the usb0 interface .
Thanks

kithamon · 2024-10-12T20:22:06Z

Well, my aim was to point @pelwell and colleagues into the right direction since it's really just installing avahi-autoipd and creating /etc/network/interfaces.d/usb0 with the aforementioned contents.

Note for anyone searching this issue: these 2 steps worked perfectly to enable USB networking on my Pi Zero 2W running Bookworm Lite 32 bit.

marko-pi · 2025-01-01T12:51:29Z

I use USB-C for diagnostics on my Pi Zero W with Bookworm and the two-step solution from ThomasKaiser also worked for me. Thanks a lot!

TenoTrash · 2025-01-11T18:04:53Z

Hello there! I manage to make it work with my laptop and both Pi Zero 2W and my Pi4, mostly following this guide:

https://github.com/verxion/RaspberryPi/blob/main/Pi5-ethernet-and-power-over-usbc.md

But what about if I do want to use the USB tethering from my phone? I have tested with two different phones and the USB shared connection remains unavailable. It do works if I use a USB-A to USB-C cable and power my Raspi 2W or 4 with an external power adapter.

Cheers!
