If I plug the device in, I get the sound Windows (10) makes when recognising a device, but in the device manager, only two things change:
Under Ports, USB Serial Port (COM12) appears.
Under USB controllers, USB Serial Converter appears.
In the Arduino IDE, I have to choose Arduino Nano manually.
From the ports, I can choose from COM"number from 3 to 11 and 14" Serial Port and COM12 Serial Port (USB). COM13 is probably not listed because my Arduino UNO uses that one.
I have downloaded, unzipped and installed the drivers:
CH34x_Install_Windows_v3_4.EXE
CDM212364_Setup.exe
Nothing changed, should I do more with the drivers other than installing them?
If I want to upload a sketch p.e. "Blink.ino" on COM12 I get the error:
avrdude: ser_open(): can’t open device : access is denied
Hi @m4ui. Which version of Arduino IDE are you using (e.g., "2.0.1")? The version is shown on the window title bar and also in the Help > About dialog.
I ask for this information because I want to give you the appropriate instructions for the IDE version you are using.
There is a known bug in Arduino IDE 2.x that can cause uploads to fail with this "Access is denied" error if you try uploading to certain boards while Serial Monitor or Serial Plotter is open. A port can only be used by one process at a time, so Arduino IDE automatically closes the port in Serial Monitor and Serial Plotter during an upload, automatically opening it again after. For some reason, that juggling of the port control is not working for certain boards.
The workaround is to manually close the port in Serial Monitor/Serial Plotter before doing an upload. Please give that a try and then let me know if you still have the error while uploading:
Serial Monitor
Click the X icon on the "Serial Monitor" tab in the bottom panel of the Arduino IDE window to close the tab:
Upload the sketch.
Open Serial Monitor again if needed (by clicking the icon on the IDE toolbar or the Tools > Serial Monitor menu item) after the upload is finished.
Serial Plotter
If you have the "Serial Plotter" window open, the procedure is a bit different from closing the Serial Monitor connection:
Close the "Serial Plotter" window.
If the "Serial Monitor" view is not already open, select Tools > Serial Monitor from the Arduino IDE menus to open it. ⓘ We must do an open/close cycle on Serial Monitor as a workaround for a bug in Serial Plotter
Click the X icon on the "Serial Monitor" tab in the bottom panel of the Arduino IDE window to close the tab:
Upload the sketch.
Open Serial Monitor and/or Serial Plotter again if needed after the upload is finished.
Please let me know if you have any questions or problems while following those instructions.
I unplugged my Docking Station (that's the only thing plugged in) restarted my Computer and tried it again. The first time I uploaded i got the error:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x76
...
the second time and all after that I got:
avrdude: ser_open(): can't open device ".\COM12": Access is denied
If I change the script, I get the "programmer is not responding" error the first time again.
OK, I think this is actually progress. You might have a "problem stack", where there were two separate problems that both affect uploads. In this case, fixing the first problem (i.e., interference from Serial Monitor) only gets you to the second problem.
I'm going to ask you to post the full output from an upload attempt when in verbose mode.
NOTE: These instructions will not solve the problem. They are only intended to gather more information which might provide a clue that eventually leads to a solution.
Please do this:
Select File > Preferences from the Arduino IDE menus.
Uncheck the box next to "Show verbose output during: ☑ compilation".
Check the box next to "Show verbose output during: ☐ upload".
Click the OK button.
Attempt an upload, as you did before.
After the upload fails, you'll see a button on the right side of the orange bar in Arduino IDE: Copy error messages. Click that button.
This copies the full output to the clipboard.
Open a forum reply here by clicking the Reply button.
Click the <CODE/> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
Press Ctrl+V.
This will paste the error output from the upload into the code block.
Move the cursor outside of the code tags before you add any additional text to your reply.

Failed uploading: uploading error: exit status 1
It is possible for a short or external circuitry connected to the Arduino board to interfere with the upload process, causing this type of upload error.
Make sure the board is not sitting on anything conductive that could short the contacts on the bottom of the board. Make sure there isn't any conductive debris (e.g., strands of wire or component leads) on the board or on the surface the board is sitting on.
If you have a shield or any external circuitry or components connected to your Arduino board, try this experiment:
Unplug your board's USB cable from your computer.
Disconnect any shields, modules, external circuitry, etc. from your board.
Plug your board's USB cable back into your computer.
Now try uploading a sketch to the board again. Does the upload succeed?
This experiment will determine whether the upload error was caused by interference from your external circuitry. If so, you can then focus your attention on identifying the specific problem with the circuit and resolving it.
NOTE: These instructions will not solve the problem. They are only intended to gather more information which might provide a clue that eventually leads to a solution.
