Hi Mark,

The PLX9052 is your PCMCIA to PCI bridge. and It is configured.

Try lspci -vv

This is old technology. You can also see that below, where
it detects the Prism2/2.5 chipset. But those prism chipsets
are very good wireless cards for 802.11b protocols. That
prism chipset implements the full features to enable it
to be configured and run as a fully functional Host Access
Point -- a wireless LAN bridge. It can also be run as a
basic wireless NIC in your laptop too.

So, your hostap_plx driver is up and running. It has
registered netdevice wifi0.

I am not sure about the ohci_hcd driver

try lsmod

does it show up as part of your wireless module stack?

try ifconfig -a    and look for wlan0

You should see it is there. But it likely isn't up and running,
without proper configuration.

Your only problem appears to be to configure the system to run it.
And you might also look for some firmware updates, cause that would
be a good thing to do next.

Hope that helps. I am really busy and have no time to fool with
this at the moment.

Thanks,
Karen
