ValueError: "Facedancer expected 1201 bates but received only 25" occured each time the scipt starts

Hello everyone,

A problem occurs while using umap.py.
When I tried executing "python3 umap.py -P /dev/ttyUSB0 -i" ValueError occurred " Facedancer expected 1201 bytes but received only 26"

Is the problem is in the HW?
Tested different targets and each time when I start the script this issue is displayed.

The same issue was observed if there is no connected target

.

This exception often indicates an HW issue, either in the Facedancer or its connection to the host. See the troubleshooting section of Umap2

You might also consider using umap2 instead.

All of the recommendations done but the problem still occurs.
With UMAP2 the same problem was observed.
Hello,

I think that the problem is not with the HW because with dizzy fuzzing tool everything working as expected.
I'm using this firmware http://goodfet.sourceforge.net/dist/facedancer21.hex (not sure how up to date it is).
Thanks

This is the result of the monitor test and listapps. After the test completes Led 1 continues light as expected.
