Please, find dmesg output here: oh, so it's not really a BBB. I have never seen an EMBEST RevB3. Do you have access to that board's accessory and/or a real BBB to check ? > http://susepaste.org/88577793 nothing interesting there. You have ES 2.0 silicon, which should work just fine. > I've also measured voltage on USB (between GND and +) when the device > is plugged in, it is 4.7V (not sure what does it mean). Hmm, if your device draws more than 100mA, 4.7V is on the borderline. I just checked my BBB and it's sourcing 5.046V when I attach a device which draws 25 ~ 45 mA. cheers -- balbi
