Question 1

Install fails or driver won’t load?

Accepted Answer

Run the CH341SER installer as administrator. On 64-bit Windows, if blocked by signature enforcement, temporarily disable it or use the signed WHQL release. Reboot after install.

Question 2

Device not detected / COM port missing?

Accepted Answer

Try a different USB cable and a direct rear port. In Device Manager, check Ports (COM & LPT) and Universal Serial Bus controllers. If a warning icon appears, update manually to CH341SER. For CH341A EEPROM/parallel use, confirm the correct mode and that no other CH341 device is attached.

Question 3

Version conflicts / old driver returns?

Accepted Answer

Uninstall existing CH341 drivers and bundled vendor copies, select “Delete driver software,” reboot, then install the latest WinChipHead CH341SER package. Avoid mixing CH340/CH341 vendor driver sets.
