At this link:
Note: A Wi-Fi adapter will probably need more power than the Raspberry Pi USB port can provide, especially if there is a large distance from the Wi-Fi adapter to the Wi-Fi Access Point, or it is transferring large amounts of data. Therefore, you may need to plug the Wi-Fi adapter into a powered USB hub.
So, is really needed of a power hub for these usb wifi adapter?
do you know how much current is provided by USB port of RPi and how can see how much current is absorbed by the usb wifi adpater?
