Thanks to Thomas Piccirello for pointing this out, and for Genaro Bonilla’s original article.
Close, but no cigar. Until now. I’m sure you, like me, have been going around in circles replacing IOSDHCIBlockDevice.kext with different versions in hopes of the card reader coming to life. It turns out you need two kexts: IOSDHCIBlockDevice.kext and IOPCIFamily.kext. XBench is reporting the card running pretty fast and it automatically mounts when inserted. No more reboots, no more swapping kexts. This one works! I’m running XxX 10.5.6 but this should work with other popular versions as well, including Kalyway.
Simply download the SD Card Reader Pack, install both kexts with Kext Helper b7, repair permissions and rebuild kext cache — reboot and you’re in action. Feel free to report your success/failure here. This may also work on other Inspirons and Dell laptop models including the Mini.

Works great with no problems.

Well, doesn’t work for me. I’ve got iPC 10.5.6. My adata 4G SDHC cards will not read through my card reader on the HP printer, or through the usb card reader. Oh well. Thanks for helping the others.

Everyone just note that for some (including myself), all you need is IOSDHCIBlockDevice.kext although for those select few of you (including Richard), both IOSDHCIBlockDevice.kext and IOPCIFamily.kext will be necessary. But, it makes no difference although when installing both kexts it would appear that it is more stable (such as not freezing when the SD card is not properly ejected) but whatever floats your boat….

Works like a charm for me.

It works great for me and unlike other posts and responses online about card readers — if you eject the card without ejecting it in your Mac first, it does -not- crash the computer. although it will appear the card is still mounted until you reboot your computer.

I was about to say that I never had this issue until I read the word laptop and realized that this would help a good bit. Thanks Tom for giving us this tip!
