Are you sure you have an rtl8723bu? Post the output of the command 'lsusb'.

The 0bda:b720 device is an RTL8723BU. Now post the output of the dmesg command in some pastebin location and post the link.
Your dmesg buffer must be quite small. It has wrapped around and is full of sequences like [ 21.056694] ====>_WriteFW 201 [ 21.057059] ====>_BlockWrite 95 i:1
Those did not come from this driver. In fact, I see no output from this driver. For completeness, please post the output of the 'lsmod' command so that I can see which drivers are loaded.
This is my lsmod & dmesg output: https://paste.ubuntu.com/p/vCyDB8pYPh/
I see that 8723bu is loaded, but once again your dmesg shows nothing useful. You clearly are presenting only part of the dmesg output. That is OK, but I will be unable to help you.
Same issue here:

I've just seen your comment in https://github.com/lwfinger/rtl8723bu/issues/46#issuecomment-255596603 and checked that sudo iw dev wlan0 scan
is working.
If the scan using iw is working, then the driver is working! It seems that the problem is with your distro;s network management packages. Sorry, but I cannot do anything with those. I use openSUSE with NetworkManager, and the driver/management software all work.
The problem in my case was fixed using sudo. Thank you for your support!!!!

I have installed the driver on a tablet EZpad 6 pro with Ubuntu 18.04. But it shows no scan results when I type sudo iwlist scan.
