Forum Post: RE: AM3352, Linux 3.14.19 USB not detecting peripherals

Try 3.16 or better 3.17. There were many fixes/enhancements and look at evmsk DTS as example. 

You need to activate at least following kernel options:

USB_MUSB_DSPS

USB_TI_CPPI41_DMA

CONFIG_AM335X_PHY_USB

and for example CONFIG_USB_ETH as gadget
