I am trying to set an AP on a Raspberry Pi 3 using an external USB WiFi card and hostapd and dsnmasq. I have managed to achieve it using the internal WiFi card but when I try to switch to my external one I got the following error:

$ sudo /usr/sbin/hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
nl80211: Could not configure driver mode
nl80211: deinit ifname=wlan1 disabled_11b_rates=0
nl80211 driver initialization failed.
wlan1: interface state UNINITIALIZED->DISABLED
wlan1: AP-DISABLED 
hostapd_free_hapd_data: Interface wlan1 wasn't started

I believe it is because by default the hostapd is using nl80211 driver. This is the output of lsusb - Bus 001 Device 004: ID 148f:3072 Ralink Technology, Corp. RT3072 Wireless Adapter. And this is the output of lshw

 *-network:1

So apparently this card is using the rt2080usb driver but when I try to put it inside the hostapd.conf and start manually the hostapd I got the following error:

$ sudo /usr/sbin/hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
Line 3: invalid/unknown driver 'rt2080usb'

And this is my hostapd.conf file:
