I have never tested Orinoco/Hermes cards with WPA, so I don't know what
to expect from them and how the driver works.

This is the WPA IE wpa_supplicant is trying to use and I did not see any
AssocInfo events updating it. Could you please verify with a wireless
sniffer that the WPA IE in Association Request matches with this one?
The AP will verify that they do and will reject 4-Way Handshake if there
is a mismatch. One possible reason for the debug log from Cisco AP would
be in the AssocReq using 26-byte WPA IE. If this is the case, the driver
would need to either use the WPA IE generated by wpa_supplicant or it
would need to notify wpa_supplicant about the WPA IE used in AssocReq by
using EVENT_ASSOCINFO.
