Thank you for your answers.
The sticks are:
1) Astrometa T2 Hybrid DvbT/T2/C/Analog/FM Stick (15f4:0135): works with updatelee drivers.
Had problems with normal kernel drivers and with media build drivers. It doesn't work in Libreelec 8.2.5 and 9.0
2) Geniatech HDStar Dvb-S2 v 3.0 (14fd:3000) (old version, not with m88ds3103b): works with updatelee drivers
It doesn't work in Libreelec 9.0 but works in 8.2.5
