Reminds me somewhat of certain keyboard MCUs that would also brick when fed certain lighting commands. OpenRGB ended up having to disable the particular module from running automatically on that hardware. (Although the vendor software would also trigger said bug, on occassion.) Unfortunately, the usual way for triggering the in-system programming mode required sending a usb hid report, but affected devices wouldn't even enumerate anymore. (Assuming it was even firmware corruption and not some other undefined behaviour causing hardware damage)
