I've got a couple of old/big Wi-Fi dongles from BlueNEXT. Had them for years, they work fine in my laptop. I also had one working in my Pi. Now though neither will power up. My battery pack has 2 outputs one at 1ma and the other is 1.5ma, tried both, just in case it was a power issue. Then tried powering the Pi via a mains adapter just to be sure. Still no joy though. The Pi just dosen't seem to recognise that they are connected. Anyone got any ideas why they would work one minute and not the next????
They are by the way excellent dongles which have served me really well over the last few years and stillwork fine in my laptop.
