Hi Robert,
it's solved. Hardware, the USB connector.
Was able to solder, now it works fine.
Sometimes there was a second entry with lsusb. Then I found out, it's the
connector, with a little pressure it worked.
Then microscope, solder iron....
I spent 2 days and nights on that 😭
But I learned a Lot
Thanks to all
Kasimir
