hostapd: nl80211 driver initialization failed

[cagnulein]

Did anyone try to use this adapter with hostapd? I've got always a nl80211 driver initialization failed

This is my hostapd configuration (works fine with the wlan0, the builtin wifi on the raspberry 4)

interface=wlan1
driver=nl80211

hw_mode=g
channel=11
ieee80211n=1
wmm_enabled=1
#ht_capab=[HT40][SHORT-GI-20][DSSS_CCK-40]
ht_capab=[HT40][SHORT-GI-20]
macaddr_acl=0
ignore_broadcast_ssid=0

# Use WPA2
#auth_algs=1
#wpa=1
#wpa_key_mgmt=WPA-PSK
#rsn_pairwise=CCMP

# Change these to your choice
# This is the name of the network
ssid=Pi3-AP
# The network passphrase
#wpa_passphrase=raspberry

ctrl_interface=/var/run/hostapd
