This "can't set com-state for ..." error occurs when uploading to the boards that use specific batches of the WCH CH340 USB chip. The problem only occurs when using the latest version of the CH340 driver.

The workaround for the problem is to perform a "roll back" to an older version of the driver that is compatible with these problematic "CH340" chips. 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
  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.
  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 (COMn)" under the "Ports (COM & LPT)" section (where "COMn" is some serial port e.g., COM4). Double click on that item.
    The "USB-SERIAL CH340 (COMn) Properties" dialog will open.
  17. Select the "Driver" tab of the "USB-SERIAL CH340 (COMn) 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 (COMn)" dialog will open.
    2. Click on "Search automatically for drivers" in the "Update Drivers Device - USB-SERIAL CH340 (COMn)" 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.
      :red_exclamation_mark: 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 topic 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 (COMn)" dialog.
      The dialog will close.
  19. Click the "Roll Back Driver" button in the "USB-SERIAL CH340 (COMn) 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 (COMn) 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.

yeah it says that

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.
  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 (COMn)" under the "Ports (COM & LPT)" section (where "COMn" is some serial port e.g., COM4). Double click on that item.
    The "USB-SERIAL CH340 (COMn) Properties" dialog will open.
  9. Select the "Driver" tab of the "USB-SERIAL CH340 (COMn) 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 (COMn) 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 (COMn)" device to appear under the "Ports (COM & LPT)" section of the Device Manager tree.
    :red_exclamation_mark: This will take a couple of minutes as Windows must first automatically reinstall the driver.
    :red_exclamation_mark: 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
  17. Wait for the download to finish.

    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 (COMn)" device under the "Ports (COM & LPT)" section.
    The "USB-SERIAL CH340 (COMn) Properties" dialog will open.
  26. Select the "Driver" tab of the "USB-SERIAL CH340 (COMn) Properties" dialog.
  27. Click the "Update driver" button.
    An "Update Drivers Device - USB-SERIAL CH340 (COMn)" dialog will open.

Please slow down a bit. You need to give people time, they also have other things to do.

Here is the error I get when uploading any code. I am using the Blink Example for this exercise. IT may also be worth mentioning that Arduino IDE does not automatically recognize my Nano. I have tried all the different Processors and most of the Programmer settings. Get Board Info isn't super helpful, and returns this:

If you expect it to state that it's a Nano under Tools → Ports that will not happen because your board uses a generic srial-to-usb adapter.

Does that port disappear when you disconnect the board?

16

Ok, thank you for the reply! The port /dev/cu.usbserial-110 appears and disappears immediately upon plugging and unplugging the nano. I have seen it (rarely!) come up as /dev/cu.usbserial-210 as well, but usually it's 110. I also have a Bluno nano V1.3 by DFRobot, and it works very well. It shows up as /dev/cu.usbmodem-1101.

You mentioned that you tried different processors.

This indicates the "new" bootloader. Please verify (again) that the "old bootloader" does not work.

Please take clear photos of the top and the bottom of the board and post them here; you can drag and drop them (but might need two posts). We should be able to read the print in the ICs (CH340 (according to the VID/PID) at the bottom, 328P on the top).

Well, I tried the old bootloader again, and it worked. I am sure I tried it before, but this time it worked. (insert USB meme here)

For interest's sake, the microprocessor is an Atmel Mega328P, and the driver is the CH340G.

I may look into faulty connections on the board that might be causing intermittent issues; the soldering on the headers looks pretty messy.
