20250410飞凌的OK3588-C核心板接USB3.0接口的热像仪在Linux R4下的USB状态的确认
2025/4/10 15:11
缘起：需要在 飞凌的OK3588-C核心板 Linux R4下接 USB3.0接口的热像仪。
如果不适用type-C的座子，干扰巨大，热像仪直接无法打开。
将 type-C 转 type-C 的C-C线剪掉一段的type-C头，直接焊线到地板上，热像仪可以打开。
由于为了做延长线，在焊线处往上打开屏蔽层大概2厘米，热像仪打开之后大概2.5s秒钟即死掉。
【请严重注意：9线/9针？的type-C线不具备完整的type-C功能，可能会出现正插的时候识别为USB3.0，反插USB2.0的情况。】

注释：USB3.0接口的热像仪 的设备号是：ID 04b4:02f7
挂载在 008# 号USB总线上了。
Bus 008 Device 001: ID 1d6b:0003
注释：由于8号总线是USB3.0接口：ID 1d6b:0003
因此，此时 USB3.0接口的热像仪也挂载在USB3.0的接口上。
可以正常打开/出图。
其他还有USB2.0的 接口：ID 1d6b:0002
和USB1.0/1.1的接口：ID 1d6b:0001
