SMC 2632 (PLX) Ad-hoc mode fails

since two weeks, I'm trying to get two (PLX-based) SMC2632 cards to talk
with each other in Ad-hoc mode. I have tried different versions of the
orinoco-driver with no success. Here are some diagnostics made with
After loading the driver, on both sides the following commands are
iwconfig eth0 essid OM79
iwconfig eth0 mode Ad-hoc
According to the manual of the cards, the light should be blinking when
the card is set to Ad-hoc mode, but if I set up the second card while
the first card is in Ad-hoc mode, the light is on permanently.
iwconfig gives the following on the first card:
eth0 IEEE 802.11-DS ESSID:"OM79" Nickname:"Prism I"
Mode:Ad-Hoc Frequency:2.462GHz Cell: 00:00:00:00:00:00
Bit Rate:2Mb/s Tx-Power=15 dBm Sensitivity:1/3
Retry min limit:8 RTS thr:off Fragment thr:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
on the second card it gives the same, but the Cell field is not null.
Here are the messages given during the initialisation of the second
card (slightly edited):

eth0: WEP supported, 104-bit key

I also tried to interchange the two iwconfig commands, but then it said,
that this firmware needs an essid to work in Ad-hoc mode.
Has someone yet made this card to work in Ad-hoc mode?
