I saw this phenomenon in a report from Patrick. There seems to be something
on the board i don't know about yet. Maybe its an eeprom with the firmware.
We have to learn how to control it later.

Hm, this might depend on the distribution you use. For me, the location has to
be /usr/lib/hotplug/firmware/

You might be fooled by this: The driver deals with the firmware when the
device gets opened, so i.e. when you start tzap. Then you will find the
appropriate messages and in your case hopefully the failed download.
Please check.

Maybe, but the chip yust tells nonsens until it is initialized (and locked)

Good luck
