Didn=B4t help either. With PCMCIA cards hotplugging always worked for me.=20
Why shouldn=B4t it with Express Card?

I am pretty much sure that Linux kernel 2.6.39, udev 0.170 and pcmciautils=
=20
18 have some trouble to see the Express Card slot on that modern notebook.=
=20
I was able to try the Delock eSATA card in a ThinkPad T520 of a comrade=20
who uses Windows. Windows recognized it out of the box.

So unless the Express Card slot is broken in my ThinkPad T520 Linux just=20
doesn=B4t recognize it at the moment.

lspcmcia also displays some output when no card is installed:

# lspcmcia=20
Socket 0 Bridge:   I[yenta_cardbus] I(bus ID: 0000:1c:03.0)

(On another laptop from a comrade.)

On my laptop:

merkaba:~> lsmod | grep yenta
merkaba:~#1> cd /lib/modules/2.6.39-1-amd64=20
merkaba:/lib/modules/2.6.39-1-amd64> find -iname "*yenta*"

merkaba:/lib/modules/2.6.39-1-amd64> modprobe yenta_socket
merkaba:/lib/modules/2.6.39-1-amd64> lspcmcia
merkaba:/lib/modules/2.6.39-1-amd64> lsmod | grep yenta

So no fish.

I consider opening a kernel bug report about this one, unless someone else=
=20
has another suggestion.

Ciao,
