Hello,
This question is similar to the my previous post http://support.logicpd.co...t/1661/Default.aspx, but other consequences (effects) happens.
I configure Linux image to load USB Mass storage gadget, so my board will be seen as USB device. This works and I am able to transfer files over MMC card and USB, but again after some time there are some warnings from kernel
Jan 1 00:19:05 Mynd user.info kernel: [ 1147.432952] Setting A idle...
Jan 1 00:19:05 Mynd user.warn kernel: [ 1147.436523] omap_device: musb-omap2430.-1: new worst case activate latency 0: 152587

, and it seems like USB is reconfigured to the Host mode, and processor give 5V on the VUSB net(pin).
It is very strange and dangerous for my system, because I have also battery charger connected to the VUSB pin.
Also it seems like it happens on several devices, not at all devices.
