About This File
VoodooSDHC for Jmicron JMB38X with pci197b,2381.
Works on Lenovo y450 with ML 10.8.2. Sleep works too. Tried upload 200mb file on 1 gb microsd - works. Only one bug - remove your card while sleep causes freeze.
If does not works, try to change IONameMatch in Plist to your values, that you can see in IORegistryExplorer.
UPD: Funny glitch - if your laptop has a plastic cover for the card slot, do not use it, because the driver thinks it's SD card and tries to read the data from it, and the system freezes.
