I'm guessing the 'Opcode 0x0c03 failed' and 'Port 007: Dev 005, If 2,
Class=Wireless, Driver=[none], 480M' are to blame here?
I've done a lot of searching and troubleshooting, but couldn´t find anything
about this particular device ID: 13d3:3585
bluetoothctl gives me:
[bluetooth]# list
[bluetooth]#
any other command will give: "no default controller available".
systemd bluetooth.service is enabled.
Let me know if more info is needed (I don´t do this every day), or if I should
contact a maintainer directly.

I have a similar/same device and it's working fine here.
Kernel 6.7.4 + latest firmware.
No idea what's going on.

Thank you for taking a look anyway. Which Linux + version are you using? Do you
get the 'Opcode 0x0c03 failed' and 'Port 007: Dev 005, If 2, Class=Wireless,
Driver=[none], 480M' with the commands above?

> Which Linux + version are you using?
Your problem is solely with the kernel. It doesn't matter which distro I use
(that's Fedora but I have/use my own kernel config).
> Do you get ...
Nope, nothing.
Using git log find the person(s) who contribute to/write this driver and send
them all this info.
The way kernel bugzilla is set up, many respective developers never get a wind
of what's being discussed here, so they are simply not aware.

You should post results from terminal for
sudo cat /sys/kernel/debug/usb/devices| awk '/3585/' RS=
The bluetooth devs usually want that info. I am guessing that you will need a
kernel patch similar to
https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/drivers/bluetooth/btusb.c?id=f0ad26ee822b197f2421462df9c358a5687fddfd
but it would be at about line 610 of btusb.c and be
{ USB_DEVICE(0x13d3, 0x3585), .driver_info = BTUSB_MEDIATEK |
BTUSB_WIDEBAND_SPEECH |
BTUSB_VALID_LE_STATES },

Thanks Jeremy. I compiled btusb.c with that change and it works.
For completeness, here's the requested output of
