AM3352 不识别4G模块

Other Parts Discussed in Thread: AM3352

AM3352和4G模块通过USB接口连接，硬件设计时只连接USB的DP和DM管脚，4G模块直接有电源供电，芯片其他USB管脚全部悬空，请问这样有问题吗？

启动log如下

    usb 接鼠标，U盘可以正常工作吗？

    usb部分的电路设计有截图吗？

    使用的是mini-pcie插座，没法试验鼠标和U盘

    看了您的原理图，建议您参考ti的evm板进行usb部分设计，vbus和drv vbus都没有接，软件不支持，所以会报出上面的错误

    在目前这种连接方法，能通过软件规避么？

    问一下，如果AM只做host，VBUS也需要连接是吗？

    软件方面，请您参考 linux-3.14.26-g2489c02/Documentation/devicetree/bindings/usb/am33xx-usb.txt ， 对linux-3.14.26-g2489c02/arch/arm/boot/dts/am33xx.dtsi 中的dr_mode 进行修改。

    现在把vbus拉倒5V了，dr_mode改成host了，但是也没识别，但是输出

    原理图没改，只是在板卡上飞线了，ID接地，VBUS直接5V，DrvBUS没接

    在 board-am335xevm.c     中请参考：


    static struct omap_musb_board_data musb_board_data = {
    .interface_type = MUSB_INTERFACE_ULPI,
    /*
    * mode[0:3] = USB0PORT's mode
    * mode[4:7] = USB1PORT's mode
    * AM335X beta EVM has USB0 in OTG mode and USB1 in host mode.
    */
    .mode = (MUSB_HOST << 4) | MUSB_PERIPHERAL,//MUSB_OTG,
    .power = 500,
    .instances = 1,
    };

    根据您的usb口进行修改。

    这个问题没见过，还是怀疑电路设计的问题。 这样吧，您把修改了，飞线后的电路图贴出来，我内部看看，看软件能不能改，但不能保证软件能解决这个问题。

    我们的软件是依据evm板上的usb电路设计做的。
