hotplug + pcmcia-cs: how?

hotplug + pcmcia-cs: how?

[Erik Mouw]

Hi all,

I'm running linux-hotplug on a 2.4 system. So far I'm impressed, every
USB device I plug in just works. Unfortunately hotplug and pcmcia-cs
hang my system when I insert a network card (3Com Megahertz 574B).

The hotplug README says:

  On Kernel 2.4 based systems, you may want to avoid installing the separate
  "pcmcia_cs" package.  It's not integrated with kernel hotplugging, and
  appears not to handle Cardbus as well as needed.  On the other hand, if
  you need to use PCMCIA (16 bit) cards, you'll likely need it.

Well the 3Com is a 16 bit card, so I need pcmcia-cs (it doesn't get
detected without it). If I stop hotplug before I insert the card,
pcmcia-cs detects the card and sets it up properly. After that I can
safely enable hotplug and plug any USB device I want.

Hardware:
- Asus M8300 laptop Celeron(Coppermine) 500, 128MB, Intel 440MX chipset
- 3Com Megahertz 574B
- Logitech M-BA47 USB mouse
- Wacom Graphire USB
- no name USB audio device (with Philips UDA 1321)

Software:
- linux-2.4.2
- debian 2.2 (potato) with critical packages updated
- hotplug-20010228
- pcmcia-cs-3.1.24

Any idea how to get this working at all?

That sounds like a kernel configuration problem.  Double-check that the
following kernel configuration items are set in your kernel's .config:

CONFIG_PCMCIA=y
CONFIG_CARDBUS=y
# CONFIG_I82365 is not set -- important!
CONFIG_NET_PCMCIA=y
CONFIG_PCMCIA_3C574=m # or =y, your choice

Bingo, CONFIG_I82365=y. So how to proceed? Sure, recompile kernel with
CONFIG_I82365 not set, but should I also remove pcmcia-cs?

No need, pcmcia-cs should take it in stride...

OK thanks, that did the trick. I had to load yenta_socket instead of
i82365 and now I can hotplug both PCMCIA and USB devices.
