1 . USB is working for Host/Mass storage (Mouse/Pendrive) But it is not working as a device
2 . PC is not detecting the board via USB(Even device manager, PC not able to recognize the usb)

Hi Igor,
I was using windows 7 and (We have around 6 development board)It is working with all the board except one board.
Is that fine for your question/ Still you need the mfg tool and environment details?
Note : Issue board was working fine and Issue occured after N number of reflashing the image via mfg tool
Please let me know if you need any details.

Bruno
Hi Bruno
if this just one board then this may be soldering issue,
one can resolder processor.

Hi Bruno
please check with oscilloscope that USB_ID is high and
USB_H1_VBUS or USB_OTG_VBUS are powered.
