进 device 模式，能调用 USBC_EnableDpDmPullUp，但是 D+ 脚没有拉高，所以接电脑没反应。请各位大神指点下，多谢了！

你是怎样进入device模式的？
我也在搞f1c100s的device模式，驱动加载都没问题，就是usb插电脑没反应
尝试过改设备树文件，强制指定device模式，都没有效果
udc的状态明显没识别usb端口状态
不知道是不是要指定vbus_det 的管脚？你是用主线 linux 吗?
据说主线linux 还没驱动 usb.
用的这个里面的 kernel：

修改 sunxi_usb_device_enable：
is_udc_enable = 1; // 添加这句 ！！！
if (udc->driver && is_udc_enable) {
sunxi_udc_enable(udc);
cfg_udc_command(SW_UDC_P_ENABLE);
}
DMSG_INFO_UDC("sunxi_usb_device_enable end\n");离线
这样改完, device 就可以跑起来了？
可以枚举，但是我测试 RNDIS 还有问题，INT 节点通讯有问题。

这样哦，那说驱动 usb device 问题不大了，昨天一直纠结的 usb device 时钟没有配置不知道是什么问题了？
https://whycan.cn/t_1522.html 16楼
usb device 能工作的。在 dts 中配置 usb_port_type 为 2 就可以
usbc0:usbc0@0 {
device_type = "usbc0";
compatible = "allwinner,sunxi-otg-manager";
usb_port_type = <2>; /* 0: for device, 1: for host */
usb_detect_type = <1>;
usb_detect_mode = <0>;
//usb_id_gpio = <&pio PD 9 0 1 1 1>;
usb_id_gpio = <&pio PE 2 0 1 1 1>;
//usb_det_vbus_gpio = <&pio PD 10 0 1 1 1>;
usb_det_vbus_gpio = <&pio PE 2 0 1 1 1>;
//usb_drv_vbus_gpio = <&pio PD 11 1 1 1 1>;
usb_host_init_state = <0>;
usb_regulator_io = "nocare";
usb_wakeup_suspend = <0>;
usb_luns = <1>;
usb_serial_unique = <0>;
usb_serial_number = "20080411";
rndis_wceis = <1>;
status = "okay";
};离线
多谢指教，那可以动态切换吗？
你指的OTG? 应该是可以的。还没时间验证。

@szyusong 感谢分享!
你用的是主线 u-boot + bsp linux 吗？ 如果全部按照官方bsp的做法，应该是改 sys_config.fex 设备树的, 改dts 好像起不到作用。
用的这个里面的 kernel：https://bitbucket.org/qq516333132/c600.git

我把 kernel 目录抠出来单独编译的。就是那个 linux-3.10 目录。

不要编译为 module，直接和内核编译在一起试试。

装上了楼上朋友的驱动程序，果然设备无法启动，代码10.
放狗搜了一圈
权威答案:
我终于想通了。
由于响应时间的原因，设备未能成功完成某些信息的枚举。IE usb设备在枚举期间没有响应足够的时间。
一旦我修复了这个问题，我就能成功运行设备而不会出现ErrorCode 10问题。
看来得改gadget驱动了。
在 Windows 下可以使用 Bus Hound 抓包分析，我前面的帖子有写抓包的内容，问题出在中断节点 0x84 无法传输数据造成的。Windows下 RNDIS 驱动需要通过中断节点获取 device 的网卡状态变化及数据是否就绪等信息，因此中断节点无法通讯，RNDIS 就无法使用。而 RNDIS 在 Linux 下使用时，好像不会用到中断节点，所以没问题。

我的驱动，用licheepi zero+linux-4.13.0的内核是可以正常使用的，看来3.10这个版本还是有不少坑
能否提供一个用于荔枝派nano的固件（包括dtb），我对比一下。

直接编译到内核， 模块方式暂时不行，问题未知。
https://whycan.cn/files/members/3/QQ20180922173703.png
Ubuntu Linux 跑 RIDIS 基本正常。
https://whycan.cn/files/members/3/QQ20180922174606.png
Win7 枚举正常，得找个驱动装装.
在 windows 下安装 RNDIS 驱动只需要用 kernel 目录下的 Documentation/usb/linux.inf 手动安装就可以。

有一位网友搞定了licheepi nano 4.19 usb otg,但是我照着他的没搞定，晚点上传文件。
能否把相关链接发一下，大家一起努力，一鼓作气搞定这个问题。

我试了下，直接把 RNDIS 编译进内核，没反应，而且 USB ID 的管脚配置有问题。有能跑起来的启动 log 吗？

ISCR : 5303f000
PHYCTL : 00012b80
PHYBIST : 00000000几个主要的寄存器的值都差不多，但是不能枚举，不知道问题出在哪儿。

3.10 内核的 RNDIS 搞定了。
f1c100s 的手册中关于 USB 有这样的说明：
Supports up to 3 User-Configurable Endpoints for Bulk , Isochronous, Control and Interrupt
bi-directional transfers (Endpoint1, Endpoint2)
支持 INT 传输的只有 EP1 和 EP2，目前代码采用的是 EP4，是无法工作的。
按如下修改后，在 Windows 下 RNDIS 没问题了。
static const char ep0name [] = "ep0";
static const char ep1in_bulk_name [] = "ep1in-bulk";
static const char ep1out_bulk_name [] = "ep1out-bulk";
#if 1
static const char ep2in_bulk_name [] = "ep2-int"; // 作为 INT 节点，为了 usb_ep_autoconfig 能查询到
#else
static const char ep2in_bulk_name [] = "ep2in-bulk";
#endif
static const char ep2out_bulk_name [] = "ep2out-bulk";
static const char ep3_iso_name [] = "ep3-iso";
static const char ep4_int_name [] = "ep4-int";
static const char ep5in_bulk_name [] = "ep5in-bulk";
static const char ep5out_bulk_name [] = "ep5out-bulk"; .ep[3] = {
.num = 2,
.ep = {
.name = ep2in_bulk_name,
.ops = &sunxi_udc_ep_ops,
.maxpacket = SW_UDC_EP_FIFO_SIZE,
},
.dev = &sunxi_udc,
//.fifo_size = SW_UDC_EP_FIFO_SIZE,
.bEndpointAddress = (USB_DIR_IN | 2),
#if 1
.bmAttributes = USB_ENDPOINT_XFER_INT,
#else
.bmAttributes = USB_ENDPOINT_XFER_BULK,
#endif离线
现在我这里还有一个问题， 请教 @szyusong, USB只能工作在 device 模式才能驱动 RNDIS, 而选择 OTG的时候, 插入电脑或者U盘都是没反应的, 这个问题应该如何解决呢？
我手头的板子没法测试，得确保 usb_id_gpio, usb_det_vbus_gpio, usb_drv_vbus_gpio 这几个都有有效的管脚相对应。

方便的话共享一下手册

在其中搜“Endpoint1”。
