windows: 之前安装了Zebra打印机官方驱动所以先卸载掉驱动。再安装Zadig用Zadig工具来安装WinUSB驱动。 zadig下载Zadig - USB driver installation made easy 记住这两个数据vendorId0A5F productId :00C1 。这是打印机的供应商ID和产品ID程序中要用到。
Linuxubuntu22.04 x86_64已经内置usbfs直接下载libusb库libusb - Browse /libusb-1.0/libusb-1.0.27 at SourceForge.net
解压后安装
./configure --prefix/home/a/libusb-1.0.27/build
make -j 4
sudo make install
linux查看vendorid productId命令lsusb
将头文件和库加到项目中。
