InfoServ

What am I doing wrong? I have a DM800HD SEV2 genuin, and I've got "No CA found" I'm trying to use Optiflasher, but get the message "Failed open com port" I don't hav any com port. On the dreambox it is USB mini type B, wich is marked "Service" So I use a normal USB A to USB mini b cable to connect the PC to the Dreambox. I have Win 10 on my PC.

Thank You.
My problem was I had a wrong USB - UART driver. When I installed te right one, the problem was solved in ... 2 sec. :-)

Thanks a lot!
