Serial/Ethernet Gadget Raspberry pi zero

Question

I'm trying this 'ethernet mode' on raspberry pi zero with bullseye and bonjour installed on windows 10 following this guide Ethernet Gadget without success.

My main goal is to get control on network less environment

after editing config.txt with dtoverlay=dwc2 and cmdline.txt with modules-load=dwc2,g_ether after rootwait.

I get to this point where the raspberry pi appears in the device manager as a COM, but no RNDIS in network adapters.

and I cant use putty to connect it

this is the point I'm stuck on, I've add also ssh file to boot and I can ssh into the pi via local network

NO RNDIS

This is the message that I'm getting from putty when trying to serial connect with baud 115200

PUTTY ERROR

Does anyone manage to connect the pi in gadget mode and can assist me?

• Dirk: There doesn't seem to be a link to the tutorial you used...
• Daniel Surizon: @Dirk fixed it now
• A-J-Bauer: how did you fix it? serial baud 9600?
• Daniel Surizon: @A.J.Bauer just fixed the link for Dirk, but please let me know if there is any new progress.
• gray: I have the same issue with a RPi Zero 2 W. I'm using the exact same configuration as on my RPi Zero W, which is working. The only differences are A: Zero 2 W vs Zero W, B: Raspbian Bullseye vs Buster.

Answer 1

This is likely an issue of missing RNDIS drivers.

I worked through the same issue today, I was seeing it with both the latest Bullseye (2021年10月30日) and and the current legacy Buster (2021年12月02日) image of Raspberry Pi OS.

This thread helped me out, after installing the USB Ethernet/RNDIS Gadget from the optional drivers in Windows Update my Raspberry Pi was correctly identified as an network device.

Answer 2

The problem is Windows 10 unable to detect the USB Ethernet gadget. You need to install the drivers through a windows update or by a google search.
