10.4: A MacBook Pro 'no sleep' solution System 10.4
Tiger only hintSo, I had troubles sleeping my Macbook Pro, since I use a Sony VAIO memory card adapter (VGP-MCA20), plugged into the cardbus slot. When I try to sleep my computer, the screen turns black, then the SuperDrive is activated (I can hear the sound), and finally, the password prompt appears, asking for my password to access my session.

I also found this in the System log in Console:
May 10 14:26:12 zvetlana kernel[0]: USB caused wake event (EHCI)
I unplugged then the memory card reader, and then everything seemed to work well. Note that no memory card is inserted in the reader.

I've experienced the same issue with a Siig ExpressCard 11-in-1 Reader. If the card is in the ExpressCard slot and I close the lid, the machine repeatedly wakes and sleeps. If I leave the machine open and tell it to sleep, it wakes right back up.

I really hope there's a software fix, as I'd like to leave the card reader in the slot permanently, as I did with my cardbus reader in my Al PB.

So the solution is to unplug the card reader? No offense, but to me, that's not a solution. A friend of mine had the same issue as aedgarrube above (though using a different reader).
While this might be a short-term fix, the issue still needs to be resolved by Apple. (I'm assuming this is a driver issue with USB/EspressCard?)

Well, actually when the computer is awake with it's lid closed, there's a function that before 2 or 3 minutes it forces the mac to sleep. I think that a real solution for not sleeping it's to install the insomnia kext or running windows.
