Recently, most players hit the following issue when using the FT232 module:

  • The PC can't identify the FT232 (USBTTL) module suddenly, but it worked well previously.
  • Check the "device manager" in PC, a undefined "FT232R USB UART" displayed.
  • Try another PC, the same error and re-install driver no help.

For upper issue, you can use the following method to resolve it.

Solution

Firstly open the "device manager", as follows:

Double click, you can found the FT232 is an undefined device, even no type tag.

Don't worry, let's see the following solution:

Firstly, click the "update driver", and select "search and install driver manually"

It still has error, right? Don't worry. You have to update the driver again. Confused? Although only one device, you have to update driver twice, and the first step can be ignored.

So double the device and repeat the upper procedure.

Still update driver manually.

Select from list.

Select the type that "Port (CON and LPT)"

Use the same factory and version.

Result

This common issue relates to Windows system. Some software or system updated, and lead to the module driver doesn't work again. And use another PC, still failed, the reason should be that the driver impacts the FT232 chip's internal logic.
