|Testing the Model A using a powered USB hub|
I tried the board with Raspian OS, same SD card I have used with my other Pi. A definitive problem is that the USB port of the Model A seem to provide less current than that of the Model B!
This meant the USB-wifi could not be powered directly from the Model A while it worked fine on Model B. It works if I connect it through the powered USB-hub.
This becomes a problem for me since I intend to use it on my robot, and use the WIFI connection to program it, and it is kind of tricky to use a powered USB-hub on the robot...
I guess it is possible to buy a battery powered USB hub, but the space is quite limited on the robot...
