Patryk, your problem is you may need to open 24M OSC for HUB 2514 manually, and you have used IMX6QDL_CLK_CKO for it in the design, but this clock is not controller's clock, controller's clock has already decided at SoC dts file (imx6qdl.dtsi), you don't need to override it at board's dts file. You can try delete clock property at imx6qdl-udoo.dtsi, if it still can't work, try to open IMX6QDL_CLK_CKO at one place to test. -- Best Regards, Peter Chen -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
