I got this usb wifi dongle which worked on the laptop and cubietruck but was not even detected on cubieboard2. Suspecting it was a power issue, I used a external USB hub and voila, the dongle was detected. I have tried with two different cubieboards and got the same results. Does the cubieboard USB ports give less power/current than the others ? Has someone tested it and what is the way to determine that ?
How are you powering your Cubie2? If via the OTG, I had major problems with power out of the other USB ports.
I switched to a 2A power source to the power in connector and my USB ports then had proper power for a USB hub.
