Can't Make Bluetooth Work

Hi. First of all, i've never been able to make my BT dongle work with archlinux. It works perfectly on debian.

here are my outputs

$ lsusb
Bus 006 Device 002: ID 058f:6364 Alcor Micro Corp. AU6477 Card Reader Controller
Bus 006 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

rfkill list

$ rfkill list
0: hci0: Bluetooth
	Soft blocked: yes
	Hard blocked: no

(when i do rfkill ublock bluetooth, or unblock 0 it doesn't work at all)

$ sudo systemctl status bluetooth.service

sorry for the mess, i've tried a lot of instructions and followed lots of guides, but unfortunately no one could make my bt work.

any other idea?

Re: Can't Make Bluetooth Work

Well the very first problem is that your device is soft blocked. Now I'm not an expert with rkill and its outputs, but that could mean there is a switch on the device, your laptop/desktop, or whatever, that needs to be turned on. Or it could be your driver, which would make more sense. Now, following a lot of random instructions is a terrible idea... The arch wiki has a very nice section on bluetooth, which would, by far, be my primary source of information. If you system is a mess, try starting over with the wiki.

Good luck!

i didn't mean my pc was a mess! I've reinstaled whole arch recently because of the mess i had.
The first thing I did was following that guide, and as it didn't work for me, I tried diferent sources.

How can I change BT drivers?

Re: Can't Make Bluetooth Work

Hciconfig shows that bluetooth adapter is down. Have you tried to bring it up?

Re: Can't Make Bluetooth Work

I have the same bluetooth adapter and also get the (95) Operation not supported when I try to bring it up.

Edit: While I have almost the same output from all commands, mine is not soft blocked. (That said, it doesn't help because I still can't bring it up.)
