Thank you for your help. Checked all the dvb-usb-af9015.fw on your link. Nothing changes. Sees no receiver dongle. On windows dongle works well.
Probably not in this case.
Why might such a mistake?:
af9015: command failed:43
af9015: firmware boot failed:-1
dvb_usb_af9015: probe of 2-1:1.0 failed with error -1
