How to switch the card into ad-hoc mode?

Hello,

   I have a D-link DWL-122 wireless USB adapter with linux-wlan-ng-0.2.1-pre25.tar.gz 

driver.
   When I run "wlanctl-ng wlan0 lnxreq_autojoin ssid=foreignwlan authtype=opensystem ", 

   I get the messages:

   ssid='foreignwlan'
    authtype=opensystem
    resultcode=success

   But when I run "wlanctl-ng wlan0 dot11req_start ssid=foreignwlan bsstype=independent beaconperiod=100 dtimperiod=3 cfpollable=false cfpollreq=false cfpperiod=3 cfpmaxduration=100 probedelay=100 dschannel=6 basicrate1=2 basicrate2=4 operationalrate1=2 operationalrate2=4 operationalrate3=11" to switch the card into ad-hoc mode,

I get the messages:
message=dot11req_start
ssid='foreignwlan'
bsstype=independent
beaconperiod=100
dtimperiod=3
cfpperiod=3
cfpmaxduration=100
fhdwelltime=no_value
fhhopset=no_value
fhhoppattern=no_value
dschannel=6
ibssatimwindow=no_value
probedelay=100
cfpollable=false
cfpollreq=false
basicrate1=2
basicrate2=4
basicrate3=no_value
basicrate4=no_value
basicrate5=no_value
basicrate6=no_value
basicrate7=no_value
basicrate8=no_value
operationalrate1=2
operationalrate2=4
operationalrate3=11
operationalrate4=no_value
operationalrate5=no_value
operationalrate6=no_value
operationalrate7=no_value
operationalrate8=no_value
resultcode=invalid_parameters

And in the /var/log/messages shows:Jun 1 13:43:11 localhost kernel: prism2mgmt_start: Enable macport failed, result=-22.

I have notice "resultcode=invalid_parameters", why? How to solve the problem?

Thanks in advance for any help!

John
