Subject: Understanding PCMCIA layer

Hello,

I'm just playing with the PCMCIA layer in order to manage a WiFi
module.

I notice that giving the suspend/resume command sequence I get:

   hostname:~# pccardctl suspend
   WWPC-PCMCIA: config_skt 0 Vcc 0V Vpp 0V, flags 0 (reset 0)
   WWPC-PCMCIA: suspend_skt 0                                                      
   hostname:~# pccardctl resume
   WWPC-PCMCIA: init_skt 0
   WWPC-PCMCIA: config_skt 0 Vcc 0V Vpp 0V, flags 0 (reset 0)
   WWPC-PCMCIA: config_skt 0 Vcc 33V Vpp 33V, flags 0 (reset 0)
   WWPC-PCMCIA: config_skt 0 Vcc 33V Vpp 0V, flags 240 (reset 1)
   WWPC-PCMCIA: config_skt 0 Vcc 33V Vpp 0V, flags 200 (reset 0)                   

and giving the eject/insert one I get:

   hostname:~# pccardctl eject
   pccard: card ejected from slot 0
   WWPC-PCMCIA: init_skt 0
   WWPC-PCMCIA: config_skt 0 Vcc 0V Vpp 0V, flags 0 (reset 0)
   hostname:~# pccardctl insert
   WWPC-PCMCIA: config_skt 0 Vcc 33V Vpp 33V, flags 0 (reset 0)
   WWPC-PCMCIA: config_skt 0 Vcc 33V Vpp 0V, flags 240 (reset 1)
   WWPC-PCMCIA: config_skt 0 Vcc 33V Vpp 0V, flags 200 (reset 0)
   pccard: PCMCIA card inserted into slot 0
   pcmcia: registering new device pcmcia0.0                                        

My module support a "sleep" mode, so I shouldn't remove power supply
nor giving to it a reset impulse during suspend/resume stages but, on
the other hands, I'd like to reset it when I give the "insert" command
and turning it off when I give the "eject" command.

How I can resolve the problem? =:-o

Thanks in advance,

Rodolfo
