Hi everyone:

Recently I tried to flash my ec.bin into my chromebook.

I compiled an ec.bin on my WSL, then I copy the bin file into my chromebook, then run following cmd:

After that I restart my chromebook, however, I found my chromebook cannot detect any USB devices. What's worse, I cannot recover it via USB boot drive becasue cannot USB ...

What should I do to recover it ?

Thanks.
