ad-hoc between different types of cards

Hello!

We are trying to set up an ad-hoc network between a
Linksys WUSB11 ver 2.6 wireless card (Linux
2.4.18,at76c503 ver 10) and a USRobotics 802.11b
PCMCIA card on Linux 2.4.18-3 (hostAP 0.0.3 driver),
as part of a student project.  Although both cards are
set to ad-hoc mode, same essid and channel, we are
unable to ping one machine from one another.  Would
some one please help?


Our USRobotics card gave the following iwconfig
output:
--------------------------------------------------------------------
wlan0     IEEE 802.11b  ESSID:"test"
          Mode:Ad-Hoc  Frequency:2.437GHz  Cell:
00:00:00:00:00:00
          Bit Rate:2Mb/s   Tx-Power:-3 dBm  
Sensitivity=1/3
          Retry min limit:8   RTS thr:off   Fragment
thr:off
          Encryption key:off
          Power Management:off
          Link Quality:0/92  Signal level:-90 dBm 
Noise level:-90 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx
invalid frag:0
          Tx excessive retries:0  Invalid misc:0  
Missed beacon:0
----------------------------------------------------------------------

Then we started the atmel driver on the other machine
with USB wireless card.  The iwconfig output was as
follows:
--------------------------------------------------------------------
wlan0     IEEE 802.11-DS  ESSID:"test"
          Mode:Ad-Hoc  Channel:6  Cell:
02:00:A7:90:FE:DC
          Bit Rate=2Mb/s
          RTS thr=1536 B   Fragment thr=1536 B
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:77  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

--------------------------------------------------------------------
We noticed that CELL, signal levels and noise levels
are different in the 2 cards.  

We then looked at the syslog output after setting
"iwpriv wlan0 set_debug 0x180003" as mentioned on the
website. We found that our USRobotics card was not
even detected in the BSS table on the device startup. 
The dmesg output is given below. 

Is it likely that the two cards are incompatible or is
there any other problem with configuration?  Kindly
help.

Thank you.

With warm regards,

Dilip
