If usb worked with 3.8 but fails with 3.14, it's probally: CONFIG_USB_TI_CPPI41_DMA=y So rebuild, with: # CONFIG_USB_TI_CPPI41_DMA is not set CONFIG_MUSB_PIO_ONLY=y ps, you can also give 4.1.0-rc6 a try: sudo apt-get update sudo apt-get install linux-image-4.1.0-rc6-bone6 sudo reboot Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
