Good news! :tada:
You can now access the CR50 CCD shell directly from Windows, no Linux VM, no kernel drivers, no COM-port hacks required.

:backhand_index_pointing_right: Download (v1.1):
:link: https://github.com/vibecoder2001/Cr50Shell/releases/tag/v1.1

This release lets Windows talk to CR50 using WinUSB, making CCD access possible entirely from user mode.

:sparkles: What this does

:white_check_mark: Access the CR50 CCD Shell on Windows
:white_check_mark: No kernel drivers
:white_check_mark: No firmware changes
:white_check_mark: No serial adapters
:white_check_mark: Works with both CLI and GUI tools

If you’re used to CR50 “just working” on Linux, this brings that experience to Windows :window::penguin::right_arrow::window:.

:laptop: What’s included

The release provides ready-to-run executables for:

  • Windows x64

  • Windows ARM64

Just download the correct .exe for your system and run it
(you’ll need the .NET 8 runtime, which Windows usually installs automatically).

:wrench: One-time setup: Attach WinUSB (required)

Windows needs to be told how to talk to CR50. This is a one-time step.

Tool needed

:toolbox: Zadig
:link: https://zadig.akeo.ie/

Step-by-step

:one: Plug in your device with CCD enabled
:two: Open Zadig
:three: In the menu, enable:
Options → List All Devices
:four: Select the device labeled:

  • Shell

That’s it :white_check_mark:

:warning: Important:

  • Only replace the driver for the Shell interface

  • Do not change other interfaces unless you know what they do

:play_button: Using the tools

:desktop_computer: GUI

:laptop: CLI

  • Launch from a terminal

  • Connects directly to the CR50 shell

  • Useful for scripting or quick access

Both tools behave the same — just different interfaces.

:memo: Notes

  • CCD must already be enabled

  • This uses standard Windows USB APIs (WinUSB)

  • If the device doesn’t show up, double-check the Zadig step

:rocket: Why this matters

Until now, Windows users needed Linux or workarounds to talk to CR50.
This makes Windows a first-class option for CR50 CCD access.

If you’ve been waiting to do this without rebooting into Linux — this is it :bullseye:.

If you run into issues or have feature requests, feel free to ask. Happy hacking! :spiral_shell::locked_with_key:

Are there any videos of this being done ? I would be more comfortable following a visual guide than a descriptive one , especially since I havent done something like this before . Either way , thank you for your contribution !

How do I use this to disable firmware write protection? I’ve gotten to the point where I’m connected to cr50 and have the shell open but idk what to do from there

4

you send the same commands you would if you were using Linux or using it in a loopback configuration, as per the docs:

ccd reset factory
wp false
wp false atboot

each command should produce a non-error response from the CR50

Thank you! All 3 worked! Now I just need to decide on a distro for my pixelbook eve. Any recommendations?

I downloaded the 3 specified tools for doing this on a windows device . I got to the point where I opened zandig to choose the chromebook as selected device . It should have been picked up as “shell” , but was instead listed as “unknown USB device (device descriptor request failed) . When I attempted to install the drivers for it , it started the process and then said “driver installation failed “. Man I wish there was a video showing how to do this .been spending weeks trying to get this done and doing what ive read just hasnt been working !

ive also tried this by downloading umbutu , but that didnt work either .
