Problem with PCMCIA/PCI Bridge


I would like to use a Wireless LAN PCMCIA Card on a PC Server, so I have installed a PCMCIA/PCI bridge but when I insert the PCMCIA card into the card master nothing appens.

I've tried on a Fedora Core 5 (with the default distribution kernel 2.6.15-1) and then on a SUSE10.0 (with the default distribution kernel 2.6.13-15.8) always with pcmciautils, instead of pcmcia_cs.

On both systems I had the same audit results:

on boot all the needed kernel modules are correctly loaded
- lsmod reports:
Code:
...
pcmcia                 37176  0
firmware_class          9856  1 pcmcia

- dmesg reports:

Inserting the pcmcia card (a Toshiba wireless LAN PC Card - PA3064) nothing appens, I have tried to load manually the kernel module also (wavelan_cs). I have tried the same operations with other PCMCIA card but with no luck.

I'm sure that is not a driver o HCL problem, because the same PCMCIA card are fully operating on a PC Laptop with the same OSes.

The only thing actually, that makes me think there is something strange is the report of the command:
pccardctl ls -v

Code:
Socket 0 Bridge:        [yenta_cardbus]         (bus ID: 0000:02:0c.0)
        Configuration:  state: suspended        ready: unknown
Socket 1 Bridge:        [yenta_cardbus]         (bus ID: 0000:02:0c.1)
        Configuration:  state: suspended        ready: unknown
The string 'ready: unknown' is quite strange.

Could the PCMCIA/PCI bridge be malfunctioning or am I missing something?

Many thanks to anybody could help me.
