ZCOM 325H does not transmit frames

Hi there,

I have two cards here, a ZCOM 325 (model XI-325, h/w rev. 2.1) and a 
ZCOM 325H  (model XI-325H, h/w rev. 1.1).

If I insert the 325, the card comes up and sends beacon frames. If I
insert the 325H, there are no beacons. When trying to run the card in 
managed mode, as a client, the kernel log shows:
kernel: wlan0: LinkStatus=2 (Disconnected)
kernel: wlan0: LinkStatus: BSSID=44:44:44:44:44:44
With a monitoring machine I can see that the card does not send a frame
in neither mode. According to various posts and chipset/fw combination, 
the 325H should work. What is wrong?

Both cards have the following firmware version:
NIC: id=0x800c v1.0.0
PRI: id=0x15 v1.0.7
STA: id=0x1f v1.3.6 
I am using hostap version 0.0.3.

Thanks,
   andreas




Here is a snippet from the kernel log (identical for both cards):

I ran a "hostap_diag -a wlan0" for both cards and diff'ed the output:
