In the Arduino IDE, you should see the COM port in the "tools" menu.  
You can try another USB cable, or select the old bootloader in the "Tools / Processor" menu. Or try another USB port or try another computer.

Hi @pacific10. This "`can't set com-state for ...`" error occurs when uploading to the boards that use specific batches of the [WCH CH340 USB chip](http://www.wch-ic.com/products/CH340.html). The problem only occurs when using the latest version of the CH340 driver.

The affected users have reported that doing a "roll back" to an older version of the driver was an effective workaround. You can give that a try.

I'll provide instructions you can follow to do that:

1. Click the following link to download the previous version of the driver from the chip manufacturer's website:  
[https://www.wch-ic.com/downloads/file/65.html?time=2023-03-16%2022:57:59](https://www.wch-ic.com/downloads/file/65.html?time=2023-03-16%2022:57:59)
2. Wait for the download to finish.
3. Run the downloaded `CH341SER.EXE` file.
4. A " **User Account Control**" dialog may now appear asking " **Do you want to allow this app to make changes to your device?**". Click the " **Yes**" button.
5. A "**DriverSetup(X64)**" dialog will open. Click the " **INSTALL**" button in the dialog.
6. Wait for the driver installation to finish, as indicated by the appearance of a " **Driver install success!**" dialog.
7. Click the " **OK**" button in the " **Driver install success!**" dialog.  
The dialog will close.
8. Click the **X** icon at the top right of the "**DriverSetup(X64)**" dialog  
The dialog will close.
9. Close Arduino IDE if it is running.
10. Connect the Arduino board to your computer with a USB cable.
11. Open the [Windows **Device Manager**](https://support.microsoft.com/en-us/windows/open-device-manager-a7f2db46-faaf-24f0-8b7b-9e4a6032fc8c).
12. Select **View \> Devices by type** from the **Device Manager** menus.
13. Open the " **View**" menu.
14. If there is a **✓** to the left of the " **Show hidden devices**" menu item, click on " **Show hidden devices**" to disable it.
15. Open the "**Ports (COM & LPT)**" section of the **Device Manager** tree.
16. You should see a port identified as "**USB-SERIAL CH340 (COM_n_)**" under the "**Ports (COM & LPT)**" section (where "COM_n_" is some serial port e.g., COM4). Double click on that item.  
The "**USB-SERIAL CH340 (COM_n_) Properties**" dialog will open.
17. Select the " **Driver**" tab of the "**USB-SERIAL CH340 (COM_n_) Properties**" dialog.
18. You will see a " **Roll Back Driver**" button in the dialog. If it is not clickable, perform the following instructions:
  1. Click the " **Update driver**" button.  
An "**Update Drivers Device - USB-SERIAL CH340 (COM_n_)**" dialog will open.
  2. Click on " **Search automatically for drivers**" in the "**Update Drivers Device - USB-SERIAL CH340 (COM_n_)**" dialog.
  3. You should now see the driver installation wizard update the driver. Wait for the update to finish, as indicated by the message " **Windows has successfully updated your drivers**" in the dialog.  
❗ It is possible you will instead see the message " **The best drivers are already installed**". If so, please stop following the instructions here and reply on the forum thread to let me know. I'll provide alternative instructions you can follow.
  4. Click the " **Close**" button in the "**Update Drivers Device - USB-SERIAL CH340 (COM_n_)**" dialog.  
The dialog will close.

19. Click the " **Roll Back Driver**" button in the "**USB-SERIAL CH340 (COM_n_) Properties**" dialog.  
The " **Driver Package rollback**" dialog will open.
20. Click the radio button next to " **My apps don't work with this driver**" in the " **Driver Package rollback**" dialog .
21. Click the " **Yes**" button.  
The " **Driver Package rollback**" dialog will close.
22. Click the " **Close**" button in the "**USB-SERIAL CH340 (COM_n_) Properties**" dialog.

Now start Arduino IDE again and repeat whatever you were doing before when you encountered that error before. Hopefully this time you will not encounter that "`can't set com-state`" error during the sketch upload.

I have found that when the driver installation gets into this state, it can be solved by uninstalling and then reinstalling the drivers. After that, the "roll back" option should be enabled.

I'll provide instructions you can follow to do that:

1. Close Arduino IDE if it is running.
2. Connect the Arduino board to your computer with a USB cable.
3. Open the [Windows **Device Manager**](https://support.microsoft.com/en-us/windows/open-device-manager-a7f2db46-faaf-24f0-8b7b-9e4a6032fc8c).
4. Select **View \> Devices by type** from the **Device Manager** menus.
5. Open the " **View**" menu.
6. If there is a **✓** to the left of the " **Show hidden devices**" menu item, click on " **Show hidden devices**" to disable it.
7. Open the "**Ports (COM & LPT)**" section of the **Device Manager** tree.
8. You should see a port identified as "**USB-SERIAL CH340 (COM_n_)**" under the "**Ports (COM & LPT)**" section (where "COM_n_" is some serial port e.g., COM4). Double click on that item.  
The "**USB-SERIAL CH340 (COM_n_) Properties**" dialog will open.
9. Select the " **Driver**" tab of the "**USB-SERIAL CH340 (COM_n_) Properties**" dialog.
10. Click the " **Uninstall Device**" button.  
The " **Uninstall Device**" dialog will open.
11. Check the box next to " **☐ Attempt to remove the driver for this device.**".
12. Click the " **Uninstall**" button.  
The " **Uninstall Device**" and "**USB-SERIAL CH340 (COM_n_) Properties**" dialogs will close.
13. Disconnect the USB cable of the Arduino board from your computer.
14. Reconnect the USB cable of the Arduino board to your computer.
15. Wait for the "**USB-SERIAL CH340 (COM_n_)**" device to appear under the "**Ports (COM & LPT)**" section of the **Device Manager** tree.  
❗ This will take a couple of minutes as Windows must first automatically reinstall the driver.  
❗ It might appear first as a " **USB2.0-Serial**" device under the " **Other devices** section of the tree. Just wait for a little longer and it will appear in its final place under the "**Ports (COM & LPT)**" section.
16. Click the following link to download the previous version of the driver from the chip manufacturer's website:  
[https://www.wch-ic.com/downloads/file/65.html?time=2023-03-16%2022:57:59](https://www.wch-ic.com/downloads/file/65.html?time=2023-03-16%2022:57:59)

21. Wait for the driver installation to finish, as indicated by the appearance of a " **Driver install success!**" dialog.
22. Click the " **OK**" button in the " **Driver install success!**" dialog.  
The dialog will close.
23. Click the **X** icon at the top right of the "**DriverSetup(X64)**" dialog.  
The dialog will close.
24. Switch back to the Windows " **Device Manager**".
25. Double click on the "**USB-SERIAL CH340 (COM_n_)**" device under the "**Ports (COM & LPT)**" section.  
The "**USB-SERIAL CH340 (COM_n_) Properties**" dialog will open.
26. Select the " **Driver**" tab of the "**USB-SERIAL CH340 (COM_n_) Properties**" dialog.
27. Click the " **Update driver**" button.  
An "**Update Drivers Device - USB-SERIAL CH340 (COM_n_)**" dialog will open.
28. Click on " **Search automatically for drivers**" in the "**Update Drivers Device - USB-SERIAL CH340 (COM_n_)**" dialog.
29. You should now see the driver installation wizard update the driver. Wait for the update to finish, as indicated by the message " **Windows has successfully updated your drivers**" in the dialog.

The dialog will close.
31. Click the " **Roll Back Driver**" button in the "**USB-SERIAL CH340 (COM_n_) Properties**" dialog.  
The " **Driver Package rollback**" dialog will open.
32. Click the radio button next to " **My apps don't work with this driver**" in the " **Driver Package rollback**" dialog .

The " **Driver Package rollback**" dialog will close.
34. Click the " **Close**" button in the "**USB-SERIAL CH340 (COM_n_) Properties**" dialog.

Now start Arduino IDE again and repeat whatever you were doing before when you encountered that error before. Hopefully this time you will not encounter that "`can't set com-state`" error during the sketch upload.

But you now have a different error message 😉 Consider that progress 🙂

`Overriding Baud Rate : 115200` indicates that you're using the "328P" option under tools / processors in the IDE. Try the "old bootloader" option and if that fails the 168 under tools / processors.

The approach by @ptillisch in post #11 is to determine if there is a bootloader and if yes, which one.

If it did not flash, there is no bootloader on the 328P processor. Can you post a link to what you exactly bought. Or post a clear photo of the top so we can try to identify the microcontroller.

The usual solution is to (try to) burn the bootloader.

This error might be caused by having the wrong port selected from the **Tools \> Port** menu in Arduino IDE.

Please perform this experiment to verify that the port you have selected is your Arduino board:

1. Disconnect the USB cable of the Arduino board from your computer.
2. Select **Tools \> Port** from the Arduino IDE menus.
3. Take note of the ports, if any, listed in the menu.
4. Close the **Tools** menu.  
❗ The ports list is only updated when the **Tools** menu is re-opened, so this step is essential.
5. Connect the Arduino board to your computer with a USB cable.
6. Select **Tools \> Port** from the Arduino IDE menus. - If a new port is listed in the menu, that is the port of your Arduino board.

Select that port from the menu and try uploading again.

If the upload still fails, or if no new port appeared after you plugged the Arduino board into your computer, add a reply here to let us know and we'll investigate the problem further.
