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 }, (In reply to jeremy from comment #6) > 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 compiled btusb.c with that change and it works.

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.
