bind PCMCIA driver
« on: February 10, 2013, 01:59:24 PM »
What is the method to bind a specific driver to a PCMCIA card?

Hi tinypoodle
Not sure if this is what you are looking for:

More details as to the nature of your problem may provide more useful answers.

Well, after 48 hours of searching the web, asking around in various IRC channels and fiddling with a lot of files and settings I was rather skeptical when looking at this url... but it seems that finally did the trick, thanks a lot Rich!   ;D

What I want to achieve is to be able to switch between different drivers available for same device which used to be a piece of cake with the old pcmcia utils by changing the "bind drivername" line in /etc/pcmcia/config.

Not marking this as solved yet, as I wouldn't exclude there might be a more convenient and/or more permanent way to deal with this.

Are you referring to cardmgr, cardctl, etc?
Maybe you want to use  pccardctl  to eject a card, which should allow modprobe to unload the current driver if
you want to try a different driver.

Hi tinypoodle
Forgot to mention,  pccardctl  is part of base, some more information is here:

Believe me, I had used pccardctl and pcmcia-socket-startup and modprobe several hundred times before first posting...
Driver unloading and loading is one thing, but the issue here is how to bind a driver to the card, and with that I only succeeded with the echo to sys command from link in Reply #1.

why not create udev rules since I assume you can find out the identifiers of your various hardware?
I am not suggesting I am an expert on udev rules but I think they can be used to
a) for a certain known hardware device....run a certain script
b) for a diff known hardware device .......run a diff certain script

then create a tcz of your handiwork, and I am assuming you are hot swapping without reboot of various pcmcia devices

good luck

udev had crossed my mind and I wouldn't exclude it could play a role but my understanding about it is most minimal... Any specific suggestions would be welcome.

ok, but issue in question differs from that, it is about switching between different drivers at will for one and same device.

sorry udev no help there, but two simple scripts  (as I am simple minded) might help auto-mate it for you?
---since you already know the commands that work for you at the moment.

script 1 for driver 1, 2 the other
