Thank you for the quick reply.

The receiver is dead. Nothing is shown on the display, except for the white LED.
The USB stick is also not getting read at the USB port.
With Putty no movement is indicated at the rs232 port.
I found a k9k8go8uod.xml file for the Vu+ Ultimo and inserted it into the BCM7413 software.
I am just waiting for my hardware CY7C68013A from China to arrive, then I'll start some tries.

I'm grateful for any help.
