USB转UART线的芯片型号

买了一根PL2303TA的线，只能从minicom接收的log, 但是不能发送数据，无法login。

有经验的同学可否告知能通过UART从host发送数据到开发板的线的芯片，我再买一根。CH340，FT232，PL2303HX？

最好是Linux Host可以用的

3

普通的ch340就可以 实测

4

个人建议是ft232r/ch343，ch340的驱动兼容性一直问题很大。如果想顺便玩玩裸机开发可以搞一个ft2232h

我用 PL2303TA 连 VisionFive v1 没有问题（虽然，有时候需要在 picocom 中按 Ctrl + C 退出重试好几次），但我用的是 picocom，没有用 minicom。
