Hello list,

I see there was a discussion on this list about three months ago about
using an RTL8192CU (usb 0bda:8176) in access point mode. I've just
bought one and I've got the same problem: hostapd just prints this in a
loop until it gives up:

WPA: 00:24:23:0c:9c:2f WPA_PTK entering state PTKSTART
wlan0: STA 00:24:23:0c:9c:2f WPA: sending 1/4 msg of 4-Way Handshake
WPA: Send EAPOL(version=2 secure=0 mic=0 ack=1 install=0 pairwise=8
  kde_len=0 keyidx=0 encr=0) 
IEEE 802.1X: 00:24:23:0c:9c:2f TX status -version=2 type=3 
  length=95 - ack=1 
wlan0: STA 00:24:23:0c:9c:2f
WPA: EAPOL-Key timeout

This is with the driver from compat_wireless as of 2011-12-29.

It works fine with the driver downloaded from the realtek website
(provided that I also use their patched version of hostapd), so it's
not a hardware problem.

If anyone could point me to the area in the driver where it is supposed
to receive the missing message, I would be happy to have a go at
debugging it.

Regards,
John Williams
