Where to find Libreelec Module Drivers addon - how to install - libreelec 9.01 on Raspberry Pi 3B - Siano MDTV USB DVB-T tuner not functioning correctly

Hi,

I have a Siano MDTV USB DVB-T tv tuner stick, pre-upgrade to libreelec 9, it was functioning correctly. However, not on Libreeelec 9.01, it pixilates on some channels on a certain mux, and on another mux, refuses to tune those stations with a log entry in the tvheadend log complaining of a POLL TIMEOUT.

As it was working fine pre-upgrade, (I understand the upgrade changed the kernel version), I thought maybe the driver/firmware doesn't properly match the USB stick any longer.

First, I noticed there is a Libreelec Module Drivers addon when searching the internet, but I could not find it in any addon repository to install on my Pi3B.

Any suggestions where to look or what to do?

Thanks
