    Are micro-SD to SD adapters active?

    I've just been looking over my accumulated collection of micro-sd cards, and (for some reason) even bigger collections of micro to standard SD adapters (where the micro card slides inside the adapter). I notice that many of the adapters just have microSD printed on them but others have microSD, microSDHC and microSDXC. Do these adapters have a hidden chip in them that might limit the capability, or are some just older and so not list all the current micro card types? I.e. If I plug an microSDXC into an adapter that just says MicroSD on it, should I expect it to still work reliably or should I expect problems?

    The adapters seem too thin to contain a chip, but then, so to the micro cards themselves.

    AFAIK they're just plastic shells with traces going from the contacts on the outside to the contacts on the inside.

    I have seen adverts for MIcro card readers that plug into a USB port on a computer. I think that they are a kind of pass through connector.

    i have one like that. i bought it for a few cents from China. works with various cards. the card to USB might have a special chip inside. when you plug it in it behaves as USB.
    Read the easy to understand, lots of pics Ubuntu manual.
    Do i need antivirus/firewall in linux?
