1、檢視系統自帶的ch34x驅動
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、刪除系統中帶的比較老的版本
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、下載ch34x驅動 https://www.wch.cn/download/CH341SER_LINUX_ZIP.html
解壓後得到如下三個檔案
kangxubo@kangxubo-HKNS:~/下載/CH341SER_LINUX$ ls driver README.md kangxubo@kangxubo-HKNS:~/下載/CH341SER_LINUX$ cd driver/ kangxubo@kangxubo-HKNS:~/下載/CH341SER_LINUX/driver$ ls ch341.c ch341.h Makefile kangxubo@kangxubo-HKNS:~/下載/CH341SER_LINUX/driver$
4、檢視系統版本號
kangxubo@kangxubo-HKNS:/$ uname -r 5.19.0-38-generic kangxubo@kangxubo-HKNS:/$
5、根據自己的系統版本查詢對應的ch341.c檔案 https://elixir.bootlin.com/linux/v5.19/source/drivers/usb/serial/ch341.c
將檔案內容拷貝複製到上邊下載的驅動檔案中驚醒替換
6、編譯檔案
kangxubo@kangxubo-HKNS:~/下載/CH341SER_LINUX/driver$ make make -C /lib/modules/5.19.0-38-generic/build M=/home/kangxubo/下載/CH341SER_LINUX/driver make[1]: 進入目錄「/usr/src/linux-headers-5.19.0-38-generic」 warning: the compiler differs from the one used to build the kernel The kernel was built by: x86_64-linux-gnu-gcc (Ubuntu 11.3.0-1ubuntu1~22.04) 11.3.0 You are using: gcc (Ubuntu 11.3.0-1ubuntu1~22.04) 11.3.0 CC [M] /home/kangxubo/下載/CH341SER_LINUX/driver/ch341.o MODPOST /home/kangxubo/下載/CH341SER_LINUX/driver/Module.symvers CC [M] /home/kangxubo/下載/CH341SER_LINUX/driver/ch341.mod.o LD [M] /home/kangxubo/下載/CH341SER_LINUX/driver/ch341.ko BTF [M] /home/kangxubo/下載/CH341SER_LINUX/driver/ch341.ko Skipping BTF generation for /home/kangxubo/下載/CH341SER_LINUX/driver/ch341.ko due to unavailability of vmlinux make[1]: 離開目錄「/usr/src/linux-headers-5.19.0-38-generic」 kangxubo@kangxubo-HKNS:~/下載/CH341SER_LINUX/driver$ ls ch341.c ch341.ko ch341.mod.c ch341.o modules.order ch341.h ch341.mod ch341.mod.o Makefile Module.symvers kangxubo@kangxubo-HKNS:~/下載/CH341SER_LINUX/driver$
7、拷貝檔案到系統目錄下
kangxubo@kangxubo-HKNS:~/下載/CH341SER_LINUX/driver$ sudo cp ch341.ko /lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial [sudo] kangxubo 的密碼： kangxubo@kangxubo-HKNS:~/下載/CH341SER_LINUX/driver$ ls ch341.c ch341.ko ch341.mod.c ch341.o modules.order ch341.h ch341.mod ch341.mod.o Makefile Module.symvers kangxubo@kangxubo-HKNS:~/下載/CH341SER_LINUX/driver$ cd lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial bash: cd: lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial: 沒有那個檔案或目錄 kangxubo@kangxubo-HKNS:~/下載/CH341SER_LINUX/driver$ cd lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial/ bash: cd: lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial/: 沒有那個檔案或目錄 kangxubo@kangxubo-HKNS:~/下載/CH341SER_LINUX/driver$ cd /lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial kangxubo@kangxubo-HKNS:/lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial$ ls aircable.ko io_ti.ko navman.ko ti_usb_3410_5052.ko ark3116.ko ipaq.ko omninet.ko upd78f0730.ko belkin_sa.ko ipw.ko opticon.ko usb_debug.ko ch341.ko ir-usb.ko option.ko usbserial.ko cp210x.ko iuu_phoenix.ko oti6858.ko usb-serial-simple.ko cyberjack.ko keyspan.ko pl2303.ko usb_wwan.ko cypress_m8.ko keyspan_pda.ko qcaux.ko visor.ko digi_acceleport.ko kl5kusb105.ko qcserial.ko whiteheat.ko empeg.ko kobil_sct.ko quatech2.ko wishbone-serial.ko f81232.ko mct_u232.ko safe_serial.ko xr_serial.ko f81534.ko metro-usb.ko sierra.ko xsens_mt.ko ftdi_sio.ko mos7720.ko spcp8x5.ko garmin_gps.ko mos7840.ko ssu100.ko io_edgeport.ko mxuport.ko symbolserial.ko kangxubo@kangxubo-HKNS:/lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial$
8、檢視驅動是否安裝完成
kangxubo@kangxubo-HKNS:/lib/modules/5.19.0-38-generic/kernel/drivers/usb/serial$ lsmod Module Size Used by pcspkr 16384 0 ch341 24576 0 usbserial 57344 1 ch341 rfcomm 86016 4 ccm 20480 6 snd_soc_avs 131072 0
9、重啟電腦
sudo depmod -a
9、安裝cutecom
kangxubo@kangxubo-HKNS:~$ sudo apt install cutecom [sudo] kangxubo 的密碼： 正在讀取軟體包列表... 完成 正在分析軟體包的依賴關係樹... 完成 正在讀取狀態資訊... 完成 下列軟體包是自動安裝的並且現在不需要了： chromium-codecs-ffmpeg-extra gstreamer1.0-vaapi i965-va-driver ibus-data ibus-gtk4 intel-media-va-driver libaacs0 libaom3 libass9 libavcodec58 libavformat58 libavutil56 libbdplus0 libblas3 libbluray2 libbs2b0 libchromaprint1 libcodec2-1.0 libdav1d5 libflashrom1 libflite1 libftdi1-2 libgme0 libgsm1 libgstreamer-plugins-bad1.0-0 libigdgmm12 liblilv-0-0 libllvm13 libmarisa0 libmfx1 libmysofa1 libnorm1 libopencc-data libopencc1.1 libopenmpt0 libpgm-5.3-0 libpinyin-data libpinyin13 libpostproc55 librabbitmq4 librubberband2 libserd-0-0 libshine3 libsnappy1v5 libsord-0-0 libsratom-0-0 libsrt1.4-gnutls libssh-gcrypt-4 libswresample3 libswscale5 libudfread0 libva-drm2 libva-wayland2 libva-x11-2 libva2 libvdpau1 libvidstab1.1 libx265-199 libxvidcore4 libzimg2 libzmq5 libzvbi-common libzvbi0 mesa-va-drivers mesa-vdpau-drivers pocketsphinx-en-us python3-ibus-1.0 va-driver-all vdpau-driver-all 使用'sudo apt autoremove'來解除安裝它(它們)。 將會同時安裝下列軟體： libqt5serialport5 建議安裝： lrzsz 下列【新】軟體包將被安裝： cutecom libqt5serialport5 升級了 0 個軟體包，新安裝了 2 個軟體包，要解除安裝 0 個軟體包，有 7 個軟體包未被升級。 需要下載 136 kB 的歸檔。 解壓縮後會消耗 499 kB 的額外空間。 您希望繼續執行嗎？ [Y/n] y 獲取:1 http://cn.archive.ubuntu.com/ubuntu jammy/universe amd64 libqt5serialport5 amd64 5.15.3-1 [34.6 kB] 獲取:2 http://cn.archive.ubuntu.com/ubuntu jammy/universe amd64 cutecom amd64 0.30.3-1build1 [101 kB] 已下載 136 kB，耗時 2秒 (76.3 kB/s) 正在選中未選擇的軟體包 libqt5serialport5:amd64。 (正在讀取資料庫 ... 系統當前共安裝有 216853 個檔案和目錄。) 準備解壓 .../libqt5serialport5_5.15.3-1_amd64.deb ... 正在解壓 libqt5serialport5:amd64 (5.15.3-1) ... 正在選中未選擇的軟體包 cutecom。 準備解壓 .../cutecom_0.30.3-1build1_amd64.deb ... 正在解壓 cutecom (0.30.3-1build1) ... 正在設定 libqt5serialport5:amd64 (5.15.3-1) ... 正在設定 cutecom (0.30.3-1build1) ... 正在處理用於 desktop-file-utils (0.26-1ubuntu3) 的觸發器 ... 正在處理用於 gnome-menus (3.36.0-1ubuntu3) 的觸發器 ... 正在處理用於 libc-bin (2.35-0ubuntu3.1) 的觸發器 ... 正在處理用於 man-db (2.10.2-1) 的觸發器 ... 正在處理用於 mailcap (3.70+nmu1ubuntu1) 的觸發器 ... kangxubo@kangxubo-HKNS:~$
10、安裝完成之後還是無法使用串列埠助手，因為識別不到串列埠，是因為brltty導致的的，處理方式可以參考 https://blog.csdn.net/qq_39851127/article/details/125988455，也可以直接解除安裝 brltty
kangxubo@kangxubo-HKNS:~$ sudo apt remove brltty [sudo] kangxubo 的密碼： 正在讀取軟體包列表... 完成 正在分析軟體包的依賴關係樹... 完成 正在讀取狀態資訊... 完成 下列軟體包是自動安裝的並且現在不需要了： chromium-codecs-ffmpeg-extra gstreamer1.0-vaapi i965-va-driver ibus-data ibus-gtk4 intel-media-va-driver libaacs0 libaom3 libass9 libavcodec58 libavformat58 libavutil56 libbdplus0 libblas3 libbluray2 libbs2b0 libchromaprint1 libcodec2-1.0 libdav1d5 libflashrom1 libflite1 libftdi1-2 libgme0 libgsm1 libgstreamer-plugins-bad1.0-0 libigdgmm12 liblilv-0-0 libllvm13 libmarisa0 libmfx1 libmysofa1 libnorm1 libopencc-data libopencc1.1 libopenmpt0 libpcre2-32-0 libpgm-5.3-0 libpinyin-data libpinyin13 libpostproc55 librabbitmq4 librubberband2 libserd-0-0 libshine3 libsnappy1v5 libsord-0-0 libsratom-0-0 libsrt1.4-gnutls libssh-gcrypt-4 libswresample3 libswscale5 libudfread0 libva-drm2 libva-wayland2 libva-x11-2 libva2 libvdpau1 libvidstab1.1 libx265-199 libxvidcore4 libzimg2 libzmq5 libzvbi-common libzvbi0 mesa-va-drivers mesa-vdpau-drivers pocketsphinx-en-us python3-ibus-1.0 va-driver-all vdpau-driver-all 使用'sudo apt autoremove'來解除安裝它(它們)。 下列軟體包將被【解除安裝】： brltty 升級了 0 個軟體包，新安裝了 0 個軟體包，要解除安裝 1 個軟體包，有 7 個軟體包未被升級。 解壓縮後將會空出 8,294 kB 的空間。 您希望繼續執行嗎？ [Y/n] y (正在讀取資料庫 ... 系統當前共安裝有 216869 個檔案和目錄。) 正在解除安裝 brltty (6.4-4ubuntu3) ... 正在處理用於 man-db (2.10.2-1) 的觸發器 ... kangxubo@kangxubo-HKNS:~$
11、至此串列埠驅動安裝完成
