Bluetooth 5.0 always disabled across reboots

Hi. I would like to ask for help.

Recently i've bought TP-Link Bluetooth 5.0 adapter. It works across reboots only when i do:

rmmod btusb
modprobe btusb

But this is troublesome for me, when each time i have to do this.

After reboots, across reboots this is how my bluetooth is seen in control panel is disabled as seen on the screen:

when i do rmmod and modprobe i get this and is turned on:

I tried to to the bluetoothctl but when i do power on it shows:

No default controller available

Could be something done with this?

In dmesg when system is booting i see:

[    3.149042] Bluetooth: hci0: RTL: firmware file rtl_bt/rtl8761bu_fw.bin not found

i did, what i found on internet:

cd /lib/firmware/rtl_bt
sudo ln -s rtl8761b_config.bin rtl8761bu_config.bin
sudo ln -s rtl8761b_fw.bin rtl8761bu_fw.bin

but this does nothing.

I added to the grub:

btusb.enable_autosuspend=n usbcore.autosuspend=-1

But this also does nothing.

Any help will be appreciated and welcome.

I would like to have Bluetooth without need of rmmod and modprobe.

rfkill shows after rmmod/modprobe this:

0: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
[root@E1-531 firekage]# 

I don't have any clues or what i should do next. Kernel is newest, system is up to date.
