1、查看系统自带的ch34x驱动
kangxubo@kangxubo-HKNS:/lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial$ ls
aircable.ko ftdi_sio.ko kobil_sct.ko pl2303.ko usb_debug.ko
ark3116.ko garmin_gps.ko mct_u232.ko qcaux.ko usbserial.ko
belkin_sa.ko io_edgeport.ko metro-usb.ko qcserial.ko usb-serial-simple.ko
ch341.ko io_ti.ko mos7720.ko quatech2.ko usb_wwan.ko
cp210x.ko ipaq.ko mos7840.ko safe_serial.ko visor.ko
cyberjack.ko ipw.ko mxuport.ko sierra.ko whiteheat.ko
cypress_m8.ko ir-usb.ko navman.ko spcp8x5.ko wishbone-serial.ko
digi_acceleport.ko iuu_phoenix.ko omninet.ko ssu100.ko xr_serial.ko
empeg.ko keyspan.ko opticon.ko symbolserial.ko xsens_mt.ko
f81232.ko keyspan_pda.ko option.ko ti_usb_3410_5052.ko
f81534.ko kl5kusb105.ko oti6858.ko upd78f0730.ko
kangxubo@kangxubo-HKNS:/lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial$
2、删除系统中带的比较老的版本
kangxubo@kangxubo-HKNS:/lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial$ sudo rm -rf ch341.ko
kangxubo@kangxubo-HKNS:/lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial$ ls
aircable.ko garmin_gps.ko mct_u232.ko qcaux.ko usbserial.ko
ark3116.ko io_edgeport.ko metro-usb.ko qcserial.ko usb-serial-simple.ko
belkin_sa.ko io_ti.ko mos7720.ko quatech2.ko usb_wwan.ko
cp210x.ko ipaq.ko mos7840.ko safe_serial.ko visor.ko
cyberjack.ko ipw.ko mxuport.ko sierra.ko whiteheat.ko
cypress_m8.ko ir-usb.ko navman.ko spcp8x5.ko wishbone-serial.ko
digi_acceleport.ko iuu_phoenix.ko omninet.ko ssu100.ko xr_serial.ko
empeg.ko keyspan.ko opticon.ko symbolserial.ko xsens_mt.ko
f81232.ko keyspan_pda.ko option.ko ti_usb_3410_5052.ko
f81534.ko kl5kusb105.ko oti6858.ko upd78f0730.ko
ftdi_sio.ko kobil_sct.ko pl2303.ko usb_debug.ko
kangxubo@kangxubo-HKNS:/lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial$
3、下载ch34x驱动 https://www.wch.cn/download/CH341SER_LINUX_ZIP.html
解压后得到如下三个文件
kangxubo@kangxubo-HKNS:~/下载/CH341SER_LINUX$ ls
driver README.md
kangxubo@kangxubo-HKNS:~/下载/CH341SER_LINUX$ cd driver/
kangxubo@kangxubo-HKNS:~/下载/CH341SER_LINUX/driver$ ls
ch341.c ch341.h Makefile
kangxubo@kangxubo-HKNS:~/下载/CH341SER_LINUX/driver$
4、查看系统版本号
kangxubo@kangxubo-HKNS:/$ uname -r
5.19.0-38-generic
kangxubo@kangxubo-HKNS:/$
5、根据自己的系统版本查找对应的ch341.c文件 https://elixir.bootlin.com/linux/v5.19/source/drivers/usb/serial/ch341.c
将文件内容拷贝复制到上边下载的驱动文件中惊醒替换
6、编译文件
kangxubo@kangxubo-HKNS:~/下载/CH341SER_LINUX/driver$ make
make -C /lib/modules/5.19.0-38-generic/build M=/home/kangxubo/下载/CH341SER_LINUX/driver

ch341.h ch341.mod ch341.mod.o Makefile Module.symvers
kangxubo@kangxubo-HKNS:~/下载/CH341SER_LINUX/driver$
7、拷贝文件到系统目录下
kangxubo@kangxubo-HKNS:~/下载/CH341SER_LINUX/driver$ sudo cp ch341.ko /lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial
[sudo] kangxubo 的密码：

kangxubo@kangxubo-HKNS:/lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial$
8、查看驱动是否安装完成
kangxubo@kangxubo-HKNS:/lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial$ lsmod
Module Size Used by
pcspkr 16384 0

10、安装完成之后还是无法使用串口助手，因为识别不到串口，是因为brltty导致的的，处理方式可以参考 https://blog.csdn.net/qq_39851127/article/details/125988455，也可以直接卸载 brltty
kangxubo@kangxubo-HKNS:~$ sudo apt remove brltty
