Do all pci usb cards work with deep sleep?

    I don't know exactly what you're asking. Does "deep sleep" = hibernate? Or do you mean does it prevent sleep? Or do you mean does it continue to provide power while the Mac is asleep?



    Here's all I can help with: Mac OS X's sleep normally deactivates USB ports, network connections, and probably Firewire (never used powered or network Firewire beyond TDM, so I can't say). I haven't used a PCI USB card.



    Do you mean PCI or PCIe?

    I have read that some pci usb 2.0 cards can make deep sleep not work and was ask if any know about ones that work with it.

    That was a PCI-X and regular old PCI problem, according to some googling. I didn't see anything about PCIe in there. I didn't see any mention of G5s even as definitely having the problem. Not that I looked past the first page or two of google. So it may not be a PCIe issue at all



    If it is a PCIe issue as well as PCI and PCI-X: There's no way to know if the problem exists on the x86 platform because there are only a handful of Mac Pros in people's hands.



    Sorry I can't offer more help.

    Maybe you are thinking of certain ExpressCard/34 cards preventing the MBP from sleeping?



    It is the only problem I can recall regarding an add an on card and sleep.



    And this issue was fixed with a software update today, so all should be fine.

    Is there any way to prevent that from happening? I couldn't do it on my powerbook but that's because its a laptop. I would like it if I could download things overnight and such... any remedies?

    I don't think so. There may be a firmware hack (an EFI or OpenFirmware pref you can switch, but I don't think so. Although the Intel speed-step would work as a semi-sleep, sort of (nowhere near as effecient, but better than ON at full all night, and you can shut your LCD off.
