echo 'blacklist dvb_usb_rtl28xxu' | sudo tee --append /etc/modprobe.d/blacklist-dvb_usb_rtl28xxu.conf
and restart. On Windows make sure to properly use Zadig to uninstall the DVB-T driver.
Hi @zuckschwerdt , thanks for reply,
I have done this before due to similar problem with the rtl_test command and it solve it, but not the pothosflow issue, that it's the strange part.
I'm in ubuntu so no windows drivers problem.
What SoapySDR modules are installed? I have libiio (from SoapyPlutoSDR) claim the interface and cause some trouble. Just a guess..
I have also libiio.

Hello, any option to use the SoapyRTLSDR without uninstall the pluto libiio? since I'm using it also and it give me same problem:
SoapySDRUtil --info
shows the path to the libPlutoSDRSupport.so
module, you can just move that away and if needed move it back.
Thanks for the help but not working, tried the same with /usr/local/lib/SoapySDR/modules0.8/libPlutoSDRSupport.so but neither both solve the blocking issue.
So libiio is not interfering and you do not have any drivers loaded (look for dvb in lsmod
)?
Do you have any other processes running that could lock the RTLSDR? Is there any hint in dmesg
?
No dvb in lsmod and dmesh does hint any strange message for me:

I'll try with another ubuntu computer I have...
Thanks!.
Hello I have installed the plugin for use the rtlsdr in pothos but get this error in message window and no data is received in diagram.
the rtl test is working correctly:

and the SoapySDRUtil --probe="driver=rtlsdr" command seems like the wiki...
Thanks.
