如果牺牲Teeny的优点，就不建议楼主搞成万能的USB库。 一个人的能力实在有限，就是厂家也是好几个团队的工作量。 建议楼主， 1. 选择最常用，销量大，有特点的STM32芯片，目前有demo的还可以减少，重点优化完善。也方便测试。 2. API最好是完全彻底兼容一个或几个常用的USB库，做到无缝更换。 3. 其他的STM32，依靠使用者自己移植/分享。

@jiuxiaxixi HAL库，仍然大行其道主要是因为，整体来讲HAL库仍然是最容易使用的库 和 经过长期测试过的库。 有这样的基础，HAL库其他的问题，比如速度慢，占用内存大，等等，都是可以忽略不计的，特别是在MCU的速度和FLASH的大小都不是问题的今天。
