revised How to setup an Access Point mode Wi-Fi Hotspot?
Removed ending white spaces in the hostapd.conf examine that are very hard to troubleshoot and added a warning about it.

comment hostapd gives error nl80211: Register Action command failed: ret=-19
I was indeed related to the device not being recognized, see my accepted answer below. But in other cases your line of trouble shooting may help as well.

comment How fix hostapd invalid/unknown driver 'nl80211' error?
I had simular problem when cutting/pasting a hostapd.conf from a website: hostapd is due to a bad implementation very sensitive to whitespaces. Also make sure your interface=<device> in hostapd.conf does not end with a space character, you will get a strange "nl80211: Register Action command failed: ret=-19" error otherwise...

comment hostapd gives error nl80211: Register Action command failed: ret=-19
Thanks for your suggestion. The device drivers work and the device is enabled, because I can connect with it to an other access point. I also disabled the networkmanager to see if that was in conflict with hostapd, but that did not work. The device is made available as wlan0 as shown by 'iw list' or ifconfig.

Is this a feature of your external drive? Specifying the type might help?
