Linux distributions usually have the drivers built-in, but strict user permissions (udev rules) will prevent your flashing software from communicating with the JXMCU hardware. 1. Configure Udev Rules jxmcu driver work

这表明JXMCU适配器在驱动兼容性设计上具有独特优势：

Windows 10 and 11 strictly require digitally signed drivers. Some older or modified JXMCU/CH340 drivers lack this signature, causing Windows to block them automatically. 3. Loose or Damaged USB Ports
