    Default GA-73PVM-S2H ~ USB Port question

    Hi.

    Can someone explain what might be going on here please.

    M/B ~ GA-73PVM-S2H.

    I have a Belkin USB Hub which is connected to one of the rear M/B USB ports and works fine.
    I also have a USB Wireless Adapter which is plugged into one of the Hub Ports and works fine.
    To tidy wiring up a bit, I removed the Wireless Adapter USB plug from the Hub and plugged directly into Motherboard USB and Wireless Adaptor stops working.
    Even if I plug the Wireless Adaptor into the M/B USB port which the Hub was using still does not work.
    Plug the Hub into the M/B USB Port and and the Adapter into the Hub again and it works OK.

    Can anyone explain why the Wireless Adaptor will not work when plugged directly into the M/B but works OK in plugged into a Hub which is plugged into the M/B?
    Thanks.

    Have tried uninstalling the Adapter Driver then connecting Adapter directly to one of the mobo ports and reinstalling the Adapter driver ~ no luck just a red cross in the Taskbar connection Icon no yellow markers in Device Manager anywhere.
    This Adapter seems to only work from a powered USB Hub so looks like the answer is it needs to be connected in this way.
    Have read on the 'net that some devices require more power than mobo can supply thus could this be reason why it (Alfa Network AWUS036H 1000mW Wireless G USB Adapter) will work from a powered Hub USB port?

    OS is Windows 7.
