Are you sure it is in hci mode? To be sure run hid2hci -0. If that does not change see troubleshooting on the GitHub wiki.

Edit: I noticed distro en blueman version.

Yes, HCI Mode.

These type of problems are best addressed on the ubuntu forums. Blueman is just a frontend to BlueZ.

I did have a quick look and the problem may be related to you having a fake csr dongle. See https://askubuntu.com/questions/1168123/how-do-i-get-my-bluetooth-device-working

Blueman can not work until you can get the hci up. Once you get that fixed I suspect blueman will work without problem.
