With the original linux installed on my Beaglebone Black the scope worked but then I installed a newer debian version with a 4.1.22 kernel and now I keep getting an error with scope power: dwfcmd analoginout.txt FAILED: FDwfDeviceOpen The device needs at least 2W/400mA from USB cable. To satisfy this: - Try to use different USB cable and computer plug. - Use the USB plug on the back of the PC, not the one on the front panel. - Use short cable, do not use long cable or cable extender. - Use powered USB-hub, avoid un-powered hub. - Use 5V auxiliary power supply. USB: 0.01V 777mA AUX: 3.58V 580mA The Analog Discovery 2 has its own 5V power supply and I use the original cable I don't see a reason why this shouldn't work. Anyone with the same problem or a solution out there?
