Check the software driver installation

1) Open the Device Manager dialog from Control Panel

• Windows Vista: Start >> Control Panel >> System >> Hardware >> Device Manager
• Windows XP: Start >> Control Panel >> System >> Hardware >> Device Manager
• Windows 2000: Start >> Settings >> Control Panel >> System >> Hardware >> Device Manager
• Windows 98/ME: Start >> Settings >> Control Panel >> System >> Device Manager

The software driver is properly installed, but the USB-RS232 adaptor does not work as expected

One of the common reasons that software may not work as expected with a USB-Serial adaptor when the devcie is properly installed, is many older programs (and even some new ones) only support a limited number of COM ports (e.g. only COM1 - COM4)

If the USB-RS232 adapter is installed as COM5, it may need to be reassigned to COM1 - COM4 to work with some software.

The following outlines how to to reassign the COM port on Windows XP/2K/Me/98SE

Windows XP

1) Follow steps 1-3 of 'Check the software driver installation'above.

2) Right-click on the 'Prolific USB to Serial Port', then click Properties

3) Click on the 'Port Settings' tab. Click the 'Advanced' button.

4) In the 'COM Port Number' drop-down select the desired port number. For example if the software requires COM2, select COM2. Note the COM port must have '(in use)' listed next to it, if it does then another device with that name is already installed in the system. After selecting the desire port number, click 'OK.'

5) Click 'OK' again, and the device will show up as being on the same COM port that it was before (i.e., COM5), but should show up on the selected port name when the Device Manager dialog is closed and opened again.

6) Close the Device Manager. Launch the software to use with the new COM port.

Windows 2000, Me, and 98 SE (Second Edition)

1) Follow steps 1 2 of 'Check the software driver installation'above.

2) Right-click on the 'Prolific USB to Serial Port', then click Properties.

3) Click on the 'Port Settings' tab. Click the 'Advanced' button.

4) Uncheck 'Use automatic settings'.

5) Select 'Input/Output range'. Click on 'Change Settings'.

6) Type '02E8-02EF' in the Value box. This value will change the port to COM 4. If COM 4 is in use, you must choose another port. The values for each port are.

• COM 1: 03F8-03FF
• COM 2: 02F8-02FF
• COM 3: 03E8-03EF
• COM 4: 02E8-02EF

7) Enter the value, then click OK. Click OK again, then click Yes when the 'Creating a Forced Configuration' window appears. Click OK.

8) Restart the computer. The Device Manager can be checked, to see the COM port change.

Initially when I plugged the debugger into a usb port my pc would make a sound and it would show up in the Device Manager as a COM port. I was successfully able to debug a blink sketch. I had not connected the tx and rx wires so I was using a second usb plugged into my D1-mini-ESP32.

Then I did some more work on my project and then when I plugged the debugger in it didn’t show up in the Device Manager as a COM Port. I’m not sure if something happened to the esp-prog hardware or if I screwed up the device drivers on my PC.
Note: COM1 is on my motherboard

And, Zadig no longer shows the FDTI driver available for replacement. Is activating the FTDI drive just a onetime thing and after that the only choice is to update to the WinUSB? Is there a way to reinstall the FTDI? Interestingly in the device manager with only the ESP-Prog plugged in it shows two Dual RS232-HS devices but no COM port. Makes me think I’ve screwed something up with the device drivers.

Here is a screen shot of the Device manager with both the target board and esp-prog plugged in using separate USB cables.

I think I’ve tried all of the obvious things including: trying a different USB cable, rebooting my PC. At one point I used the Device Manager to delete both of the Dual RS232-HS devise and the FTDI COM device and rebooted my PC, no change. I’ve rerun Zadig many times but the FTDI Bus drive never shows up again. I’ve tried reinstalling the driver but that hasn’t helped.

I realize this is probably not related to PlatformIO but there don’t seem to be many that understand configuring the ESP-Prog and @manuelbl seems to understand how all of this is supposed to work.
