rtl-sdr error in linux on Orange Pi: Detected Kernel usbfs mmap() bug, falling back to buffers in userspace

Hello.

I have a problem with rtl-sdr installed in an Orange Pi with Armbian Buster.
By running the rtl_433 command or other commands that are part of the package, I get this message:

Detected Kernel usbfs mmap() bug, falling back to buffers in userspace



The software stops and ends here. How can I solve the problem?
This is my kernel installed:

Linux orangepiplus2e 5.4.35-sunxi #trunk SMP Thu Apr 23 18:06:21 CEST 2020 armv7l GNU/Linux

A question.... how did you install rtl-sdr...compile yourself or package software management?
You mention rtl_433 as part of a package. Please elaborate a little on this...
