DVBLink TVSource 6.0.0 14072 PCTV 461e Not detected

[M.F.]

First i wanted to install a second PCTV 461e Tuner at my AS5102T. That did not work with more than one Kodi-Client (the TV screen frozed at both Kodis).
Then i updated first my Asustor ADM to Version 3.0.3.RAI4. After upgrading ADM my TVSource USB-Receiver PCTV 461e is no longer detected.
Then DVBLink 5.5.0 to 6.0.0. Trial. TVSource USB-Receiver PCTV 461e is still not detected.

What can i do, that:
- PCTV 461e is detected again with my registered DVBLink 5.5.0 Version
- confugure two PCTV 461e to watch or record more than one TV-Chanel at one time?
