配置如下：

FluxBB bbcode 测试

insmod g_ether.ko信息如下：
[ 459.502260] g_ether gadget: using random self ethernet address
[ 459.508903] g_ether gadget: using random host ethernet address
[ 459.529760] usb0: MAC 22:01:32:dc:e1:b4
[ 459.534219] usb0: HOST MAC 56:6c:b8:9d:b9:36
[ 459.552964] g_ether gadget: Ethernet Gadget, version: Memorial Day 2008
[ 459.561290] g_ether gadget: g_ether ready

但是没有显示RNDIS，PC机也没有识别出USB

OTG切换到device模式了吗?

sys_config.fex中的USB我是这么配置的

我记得 adbd 是可以，你试一试adb或者串口?

是这些adb配置吗

参照 https://whycan.com/t_1626.html ，修改驱动
1.make ARCH=arm menuconfig,进入Device Drivers/USB support/USB Gadget Support,选中USB Gadget Drivers (Ethernet Gadget (with CDC Ethernet support))以及RNDIS support
2.修改sys_config.fex中的usb_port_type = 0，使usb处于device模式
3.修改sunxi_udc.c
4.修改usbc.c
同上以上步骤即可实现USB虚拟成网卡
