荔枝派F1C100S，我启动好像是正常的，OTG功能，USB插入电脑有反映WIN可以驱动加载，但是HOST功能一直不行
我插入U盘、USB网卡都没反映，lsus，出来一直具返回一行“Bus 001 Device 001: ID 1d6b:0002”；
我看PE2，插入电脑高电压，插U盘是低电压，理论是对的
以下为启动代码 ：

是不是cdc得编译成模块才能 otg?

不会吧，其实我也不需要USB连WIN。我直想接个U盘，接入个USB网口

还是说，PE2需要进行人工拉低电平

我记得这个固件可以测试otg,你试一试: https://whycan.cn/t_3400.html

收到，谢谢，这个好像是V3S的

楼主这个问题解决了没,我好像类似问题,同样固件,生成的SD卡固件USB HOST都正常的.但生成的NOR FLASH里的固件,就发现不了USB设备.
