解决Ubuntu22.04.1上安装ch34x串口驱动报 Key was rejected by service 需要签名的问题问题官网下载解压驱动包编译安装给驱动签名再来载入模块设备驱动程序问题
Ubuntu22.04.1 Linux版本5.19.0-32-generic 运行Qt串口通信 m_serialPort-open(QIODevice::ReadWrite) 时总是失败。 负责硬件的同事说可能是需要安装ch340驱动。

ncyfNCYF:~/Downloads/CH341SER_LINUX$ 原因在 readme.txt 里面有说明
// ChangeLog
// 1.0 - 1.1 modified to solve transmition between ch341 and ch341
// 1.1 - 1.2 Support high Linux kernel
InstructionsNote: 1.Please run followed executable programs as root privilege2.Current Driver support versions of linux kernel range from 2.6.25 to 3.13.x3.Current Driver support 32bits and 64bits linux systemsUsage:(load or unload linux driver of CH34x)//compile #make//load ch34x chips driver#make load//unload ch34x chips driver#make unload
// 1.2 - 1.3 Fix some bugs第七行Current Driver support versions of linux kernel range from 2.6.25 to 3.13.x的意思是linux内核的当前驱动程序支持版本从2.6.25到3.13.x 而我的是5.19.0-32-generic
所以需要去查看ch34x.c的 源代码直接复制到CH341SER_LINUX/ch34x.c 中重新make

ncyfNCYF:~/Downloads/CH341SER_LINUX$ 此时没有签名。
给驱动签名
首先依赖mokutil和shim-signed
sudo apt install mokutil
sudo apt install shim-signed
sudo update-secureboot-policy --new-key生成的证书(MOK.der)和私钥(MOK.priv)位于 /var/lib/shim-signed/mok/ 目录下。
openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -days 36500 -subj /CNDescriptive name/导入签名证书
sudo mokutil --import /var/lib/shim-signed/mok/MOK.der重新启动 电脑启动 UEFI 询问您是否要更改安全设置选择”Yes”。 将签名写入驱动
