They claim it is just A5A. So, I've booted into Angstrom with kernel 3.8.6 (which is preinstalled on eMMC), and USB works perfectly. I can read my files on usb-drive, I can grab frames from my webcam and so on. Thereby, the issue is somewhere in my kernel (or config). > Hmm, if your device draws more than 100mA, 4.7V is on the borderline.

I found no voltage regulators for 5V line on the board, so I think I just need to find other power supply. -- With best regards, Matwey V.
