标题: 3399升级 PL2303驱动

买的绿联的usb转9针,3399板子无法识别啊,在win10上没问题。
(在EC-A3399上,和RK3399proc上都试过了,同样的问题。)

不能识别为ttyUSBx;系统信息如下,

[23527.943028] usb 1-1.2: new full-speed USB device number 14 using ehci-platform
[23528.030796] usb 1-1.2: New USB device found, idVendor=067b, idProduct=23c3
[23528.030839] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[23528.030865] usb 1-1.2: Product: USB-Serial Controller
[23528.031101] usb 1-1.2: Manufacturer: Prolific Technology Inc.
[23528.031127] usb 1-1.2: SerialNumber: AMBQf103Y23

编译新的驱动,提示升级驱动
没办法卸载板子里的驱动,提示:insmod: ERROR: could not insert module pl2303.ko: Device or resource busy
卸载时:
rmmod: ERROR: Module pl2303 is not currently loaded
log:
[25678.136747] Error: Driver 'pl2303' is already registered, aborting...

不知道该怎么办了,
