SD/MMC Onboard Card Not Functioning
 

I have googled, fedoraforumed, and linuxquestioned, but to no avail, so I am posting a thread. There are several issues, listed below, but I'll hit them one at a time.

First, though potentially useless, my laptop is the ZV5000 from HP. This particular board has the built-in SD/MMC/CF(?) reader. The problem comes about that I can't seem to identify it from lspci(see below), and have tried a few things I've found elsewhere, but still had no luck. Aside from that, my synaptic pad is only acting as a pointing device, and won't respond to clicks(taps) on the pad itself. I've managed to get my wireless card running, and detecting other networks, so that's been solved. Slightly less important is my inability to find any ATI video drivers(Has Livna not released them, yet, or am I blind/looking for the wrong file/something else entirely? The only other issue is my webcam(Logitech QuickCam Messenger Communicate. I managed to get the cam working in F8, but haven't had any luck since moving up to F9. Another time, maybe. Most importantly, as I said, is the SD/MMC reader, built into the board. LSPCI follows:

Also, the output of lsusb, with no usb devices attached to the system:

If there are any parts of that that need a verbose output, or if I've left anything important out, let me know, and I'll post it, asap.

Here's hoping someone out there can see what I'm missing XD

Have you got the cardbus drivers up and running? You may not be able to access anything at all on the other side of the CardBus until you have its drivers loaded, and some devices like SD controllers are often connected to the cardbus.

Cardbus Drivers
 

I was under the impression that the cardbus drivers should have been auto-loaded, but I'll verify whether they're on, or not. I'm still kinda new to the Linux Laptop world, so it may take a little bit for me to get that going. For now, though, I'm going to get that laptop back on the bench, so to speak, and exercise some more google-fu, to try and get you a definitive answer. Thanks for the info, though! I hadn't thought to take that angle with it, and it may well send me in the right direction. I'm honestly thinking that the cardbus and the card reader *are* linked, due to the fact that I have only one PCMCIA slot, located directly below the card reader, on the laptop. As soon as I have any more info, I'll post what I get.

Okay. In going through everything I have installed, and verifying that I *do* have the pcmcia tools installed and loaded, here's what I get from /sbin/lspcmcia:

Socket 0 Bridge: [yenta_cardbus] (bus ID: 0000:02:04.0)
Socket 1 Bridge: [yenta_cardbus] (bus ID: 0000:02:04.1)

Now, since I only have one actual pcmcia slot(bottom), and the on-board card reader(above the pcmcia, physically) is in the same bus, I'm figuring it's the first device in the bus ID list. Next question is, "What do I need to do/load/edit, in order to get the card reader to respond to the system?" Here's hoping that someone out there has some insight for a Linux Laptop n00b.

Looking at my notes, I see for my own hardware:

1. The 'sdhci' driver may interfere with SD/MMC operation. So I guess I use 'modprobe -r' to remove sdhci and mmc_core and anything else related.

2. Load the modules:
tifm_7xx1
tifm_core
tifm_sd

I have another note indicating that I may have got the order wrong for those modules, but I never looked at the situation carefully because modules will be loaded in the correct order one way or other due to the dependencies.

Another note indicates that the names of the devices are something like mmcblk*.

This may not work for you (I still have no idea what chip is providing the MMC interface), but it can't do any harm to try.
