Traceback Error: USB Timeout

[bluibi5]

Posted this on the Discord and was asked to post it here:

Hello all, I'm getting facedancer set up with the Cynthion and it looks like I was successful:

$ cynthion info
Cynthion version: 0.1.6
Apollo version: 1.1.0
Python version: 3.10.12 (main, Jul 29 2024, 16:56:48) [GCC 11.4.0]

Found Apollo stub interface!
    Bitstream: Facedancer (Cynthion Project)
    Vendor ID: 1d50
    Product ID: 615b
    bcdDevice: 0104
    Bitstream serial number: 2a252adf30c460de

For additional device information use the --force-offline option.

But when I try to run the rubber ducky test script (copy/pasted from ReadTheDocs) I get a traceback error:

$ python3 ./other-rubber-ducky.py

Target host: Apple M2 MacBook Pro running Sonoma 14.6.1

I have also tried running it on a Kali 22.3 target host

I am using cynthion+facedancer from the pip install.

I plugged the target host connection into the Controller host machine, ran sudo dmesg -w, and reran the script.
Output:
[ 1151.625350] usb 4-1: new full-speed USB device number 2 using xhci_hcd

Hello - I get the same errors using a "Ubuntu 22.04.3 LTS" virtual machine (vmware)

using python v3.12.3 with cynthion+freedancer from pip install

The host running the vm is windows 10 with vmware 17

@ All, I shared my case in #179.

I had only one chance after reboot.

I can reproduce this too, and it seems like it might be an issue in the latest firmware/gateware - if I downgrade cynthion and re-run cynthion run facedancer the problem goes away.

I've finally managed to reproduce this on my side but only when using Linux as the control host.

Will update as I learn more!

Would you share the command to revert it? Plus, the version information.

Would you share the OS you're using?

[antoinevg]

I've pushed some fixes to #191 that should resolve this issue.

I'll try to do a new Cynthion release with these fixes next week but, before that, I'd greatly appreciate any feedback from anyone with the time to test it on their side!

[timoksn]

i would imagine that to test before the release i would have to build it from your commit right?

if so then i will follow these instructions https://cynthion.readthedocs.io/en/latest/developer/soc_firmware_compilation.html , let me know if i'm in the wrong path.

I am willing to help the test. Please share the instruction.
