Hey
Just bought a new (cheap) bluetooth adapter (from some company called Maxxions).
`bluetoothctl` is giving me an error: `No default controller available`.
rein ~ $ sudo bluetoothctl
Agent registered
[bluetooth]# power on
No default controller available
[bluetooth]# scan on
No default controller available

Devices:The adapter came with a little driver installer CD (for windows), which according to the text on the disk installs `RTL8761B`. I tried installing the rtl8761usb package but it didn't help.
I also tried all of these solutions from the wiki.
I also performed this hex edit of the btusb driver.

have you tried this?
create this file:
/etc/modprobe.d/btusb.confwith the following line:
options btusb enable_autosuspend=0Offline

Hey thanks for answering jonno2002. I already tried that as a kernel param, just tried it your method as well but it didn't help.

this seems to be your issue, looks like it may be fixed in future kernel version, or you can patch and build your current kernel, i cant help with the process tho your on your own.

I compiled the bluetooth-next kernel to which this patch should be applied.
The dmesg log has changed but the dongle is still not working:

Someone at the thread @jonno pointed me to was able to figure some stuff out about this driver.
For anyone interested: https://gist.github.com/nevack/6b36b82d … nt-4108046
I've abandoned all hope and returned the usb dongle.
