Hi,
does hostapd support AP mode for TP-Link TL-WN722N V2 (Realtek RTL8188EU, USB ID
2357:010c)?
When using rtl8188eu kernel module from staging [1] with
CONFIG_88EU_AP_MODE=y, AP mode does not work for neither nl80211 nor hostap driver.
Is it just configuration issue or it's just not supported?

There are number of out-of-tree kernel modules: 8188eu, the very old official
one from TP-Link [2] for v4.3 (2015). There are other forks of this official
[2], [3]. [2] mentions Monitor Mode, which suggests there could be AP mode
working.
Only very old hostapd is supported by the staging driver, and not very well.
Your best chance is to use the v5.2.2.4 branch pf
http://github.com/lwfinger/rtl8188eu.git.
This driver uses cfg80211/nl80211 commands and supports the latest hostapd.
