Any chance of making 8192cu compatible with hostapd?

[davepuchyr]

Hostapd works with the stock rtl8192cu (and rtl8192ce) modules. I get

"nl80211: Could not configure driver mode"

with the 8192cu module; see below for more info. Any chance of making 8192cu compatible with hostapd? Does it need to be dependent on the mac80211 module?

Not with this repository. There has been a renewed effort for a mainline kernel driver recently, which is your best chance. https://github.com/torvalds/linux/blob/master/drivers/net/wireless/realtek/rtl8xxxu/Kconfig
