Ok, so let's see the steps I followed.
 
1. Installed Armbian Unstable for OrangePi Zero2:
https://imola.armbian.com/dl/orangepizero2/nightly/Armbian_21.05.0-trunk.77_Orangepizero2_hirsute_edge_5.11.11.img.xz
 
2. Forced ethernet at 100 mbit/s, otherwise it did not work: added in /etc/rc.local
ethtool -s eth0 speed 100 duplex full autoneg off
 
3. Downloaded hexdump's precompiled kernel (derived from jernej's 5.11.0rc1 kernel):
https://github.com/hexdump0815/linux-mainline-and-mali-allwinner-h6-kernel/releases/download/5.11.0-rc1-stb-616%2B/5.11.0-rc1-stb-616+.tar.gz
 
4. Extracted the various parts and fixed the symlinks:
Image -> Image-5.11.0-rc1-stb-616+
uInitrd -> uInitrd-5.11.0-rc1-stb-616+
dtb -> dtb-5.11.0-rc1-stb-616+
 
5. Inside dtb-5.11.0-rc1-stb-616+, created a new folder "allwinner" and moved the 3 .dtb there; otherwise, initramfs would not find them
 
6. Rebooted. Voilà, we now have a working mainline-ish kernel (patched 5.11.0rc1) with USB support!

I have tested with the daily version of 3/30/2021.    I found that I2C worked.   USB not worked. 
Two image are added.  These images are what I have captured.
(*) Also, I have noticed that Wifi is not ready either.
