Hi, I am new in this List, i am trying to use Raspberry Pi 3 with a RTL2832U + R820T USB ISDB-T Digital Television Receiver, I am in Ecuador nad we use ISDB-T for digita air TV. I wan to make a digital TV server on my home network, and try to use TVheadend with Libreelec version of Kody that handles ISDB-T for Server. My problem is that i can not get the corect driver for this device to work with the Raspberry Pi3. Any help on a driver that get to work RTL2832U + R820T USB ISDB-T with this device?

I used this method on my RPi4 but after I installed Spyserver . I thought Spyserver already had the rtl communications built in. I now get this error:
Kernel driver is active, or device is claimed by second instance of librtlsdr.
In the first case, please either detach or blacklist the kernel module
(dvb_usb_rtl28xxu), or enable automatic detaching at compile time.

usb_claim_interface error -6
Failed to open rtlsdr device #0.

I used the blacklist as detailed in your method but I still get the error.
Any help would be appreciated.
Thanks in advance,
