Why I adb can't find my phone?

[AC Question]

I have a problem. My power button is not working, my phone shut down and I cannot power it again without the button. Volume button is also broken, so that trick don't work either. I installed Android studio for SDK tools. I'm aware I don't need the whole program but I was too dump to find and instal the toolkit alone. Then I separately downloaded platformtools.zip from the same place that included adb.exe and also specific usb drivers for my phone, Huawei Honor 6 plus. Phone is not rooted but usb debugging is on. Then I run command prompt from the location I have adp file (C:\platform-tools). When I first typed adb devices I got the following lines:
List of devices attached
* daemon not running. starting it now at tcp:5037 *
* deamon started succesfully *

daemon is probably the name of my phone. I don't remember naming it but it would be my style. Then I tried reboot command, and got the following:
error: no devices/emulators found

After this, when I type adb devices again it only says:
List of devices attached

And nothing else. Anybody have any idea why this is? Why adb is not working, what did I do wrong? How to work around it? I would be beyond grateful if somebody could help me solve this issue! I need to get my phone on asap and don't feel good taking it to the shop, I'd rather fix this myself!

The phone is charging and windows makes the connecting sound when I plug / unplug it, but it doesn't show up otherwise. I'm kinda noob and out of options, please help!

It seems that you have adb installed correctly. Daemon is the protocol used by adb to communicate with the device.

I would say you probably have a driver issue, if what you downloaded only says usb drivers it is most likely only mtp. I think you need to search for adb drivers for your device and install them. Then adb should see your device.

Now do the following steps:

1. Don't plug the phone into your USB.
2. Use the Windows Button+R combination.
3. Issue the command devmgmt.msc
4. Now plug in your device.
5. If you see an unknown device now, you need to install your phone's drivers.

Also: Try to not put your device in the file transfer mode. Leave it in no mode (so no MTP, PTP) besides adb and then try adb devices again.
