I'm currently making my own version of an Arduino Leonardo and want a way to differentiate between it and the Leonardo, I have my own bootloader with edited descriptors to change the pid ,vid , name and company but it shows up as a Leonardo if I don't change the pid and vid, and shows up as a USB Serial port if I do change them.
I'm thinking I need to write my own driver for it to have the correct name, is there any resources that can point me in the right direction?
I tried editing arduinos but it fails on install, I think the security file has something to do with that.
You can buy a code signing certificate an re-sign the CAT file that comes with the drivers. See my article on the subject.
Alternatively, you can just switch to Windows 10, which has a new driver called usbser.inf. This driver should automatically recognize the virtual COM ports on your board and configure them to be used with usbser.sys, so you don't need a driver.

Few months ago, I bought cheap arduino nano from china. Instaled all the required drivers, and tried out my frirst program.
Now I tried to upload something new, and I get this error message:
avrdude: ser_open(): can't open device "\.\COM4": System can't find given file.
I also noticed, that Tools->Ports can not be clicked. The device does not even show up in device manager.
Any Ideas?
In my first program I did also set pin 0 and 1 (RX/TX) as outputs and used them to flash LEDs. I am aware, that this probably prevents new code from beeing uploded, but it should not prevent from the device from shoving up at all. The computer talking to the USB driver, not the microcontroller.
Go to Device Manager and find the Arduino COM Port
Go to the Advanced properties of the port
Set the port # to COM1
Then un-plug your USB and plug it back in.
For the past week I have been programming an Arduino Uno with a computer running Windows 7. When I first started, I found the device on COM6 and was able to upload code no problem. Recently it suddenly stopped receiving code under the error:
Serial port 'COM6' not found. Did you select the right one from the
Tools > Serial Port menu?
The Serial port menu though is grayed out. Research has told me to open up Device Manager and update drivers but there is no other devices tab in my Device Manager. The Arduino is run off the power of the USB cable and runs the code I uploaded a few days ago just fine. What can I do to be able to upload code to the Arduino?
Update:
I installed the Arduino software on another computer and it does not recognize the Arduino either. One of the comments indicates that this could be a problem with the FTDI chip. How can I test if this is the case, and if it is, can I fix it?
There are two types of cable:
Charging Cable
Data Transfer Cable
So try changing the cable, if you have already tried every USB driver and port; or else
Install a new driver using this link, http://www.wch.cn/download/CH341SER_MAC_ZIP.html.
But after installing the driver, if it doesn't work, then change the cable.
For Linux:
To solve the problem, simply run the IDE as super user, so go to terminal and type 'sudo arduino'.
To solve this problem permanently:
In the terminal, run 'gksudo gedit'
In gedit, open the /usr/share/applications/arduino.desktop file.
Change the line Exec=arduino
to Exec=gksudo arduino. Save the file.
Similarly, do the same for Windows...
Also try to re-install Arduino driver.
The Arduino probably started using a different port. When you plug Arduinos into a different USB port it sometimes defaults to a new COM port. Check your device settings for which ports are being used and try each of those. Also try plugging it into a different USB port (if no ports are displayed) and it should register with a new COM. If that fails reboot your machine and repeat the above. If that fails reinstall the Arduino USB driver and repeat above. If that fails you might have fried your Arduino's USB chip (or some other hardware on the Arduino).
For Linux: Vinayk93 is completely right. Adjust the serial port's access rights like so:
$ cd /dev/ ; ls -l ttyA* -- find the right portname, then
$ sudo chmod 666 ttyACMx -- x is 0 or 1
I bought an Arduino Uno recently. After getting the necessary cables, I decided to upload an example to the chip.
Instead of seeing that Blink, I received an error like processing.app.SerialException: Serial port 'COM1' not found. Did you select the right one from the Tools > Serial Port menu?
Yes, I tried that. But even Serial Port Monitor doesn't seem opening. Then again, I get some exception that isn't worth mentioning.
After I found out that my Serial COM ports don't work (via Portmon.exe), and figuring out that I may even don't have any (there is no COM port in Device Manager), I also tried to download a driver for COM port, but it has also failed.
Some say that it's because of my Acer Aspire 5742's motherboard. Some say that the reason is Windows 7.
Long story short, I'd really appreciate if someone can help me with my COM port problem and mend my broken dreams.
Installing Drivers for Arduino in Windows 8 / 7.
( I tried it for Uno r3, but i believe it will work for all Arduino Boards )
Plugin your Arduino Board
Go to Control Panel ---> System and Security ---> System ---> On the left pane Device Manger
Expand Other Devices.
Under Other Devices you will notice a icon with a small yellow error graphic. (Unplug all your other devices attached to any Serial Port)
Right Click on that device ---> Update Driver Software
Select Browse my computer for Driver Software
Click on Browse ---> Browse for the folder of Arduino Environment which you have downloaded from Arduino website. If not downloaded then http://arduino.cc/en/Main/Software
After Browsing mark include subfolder.
Click next ---> Your driver will be installed.
Collapse Other Devices ---> Expand Port ( its in device manager only under other devices )
You will see Arduino Written ---> Look for its COM PORT (close device manager)
Go to Arduino Environment ---> Tools ---> Serial Port ---> Select the COM PORT as mentioned in PORT in device manager. (If you are using any other Arduino Board instead of UNO then select the same in boards )
Upload your killer programmes and see them work . . .
I hope this helps. . .
Welcome
Did you install the drivers? See the Arduino installation instructions under #4. I don't know that machine but I doubt it doesn't have any COM ports.
I've had my drivers installed and the Arduino connected through an unpowered usb hub.
Moving it to an USB port of my computer made it work.
Abstract: Steps of How to resolve "Serial port 'COM1' not found" in fedora 17.
Today install the packages for Arduino in Fedora 17.
(yum install arduino) and I have the same problem: I decided to upload an example to the chip. and got the same error "Serial port 'COM1' not found".
In this case when I run Arduino program, some banner appears which warns me that my user is not in 'dialout' and 'lock' group. Do you want add your user in this groups? I click in add button, but for some reason the program fail and not say nothing.
Step1: recognize the Arduino device
unplug your Arduino and list /dev files:
#ls -l /dev
plug your Arduino and go and list /dev files
#ls -l /dev
Find the new file (device) that was not before plugging, for example:
ttyACM0 or ttyUSB1
Read this properties:
ls -l /dev/ttyACM0
crw-rw---- 1 root dialout 166, 0 Dec 24 19:25 /dev/ttyACM0
the first c mean that Arduino is a character device.
user owner: root
group owner: dialout
mayor number: 166
minor number: 0
Step2: set your user as group owner.
If you do:
groups <yourUser>
And you are not in 'dialout' and/or 'lock' group. Add yourself in this groups run as root:
usermod -aG lock <yourUser>
usermod -aG dialout <yourUser>
restart the pc, and set /dev/<yourDeviceFile> as your serial port before upload.
unplug not necessary,just uninstall your port,restart and install driver again.you will see arduino COM port under the LPT & PORT section.
This fix / solution worked for me:
Device Manager --> Ports --> right click on Arduino Uno --> Update Driver Software --> Search automatically for updated driver software
I restarted my computer and then opened the IDE again and it worked while none of the above did.
Maybe you have to do the things above as well, but make sure to restart the computer too.
I have a number of Windows 2000 systems that we are trying to use to program the new Arduino Uno and Mega devices. These boards now come with a USB connection, an upgrade from the prior FTDI. I'm not able to download the Arduino code into the board from a Windows 2000 system
The supplied drivers are *.inf files that modify the standard USB driver that comes with Windows (in this case Windows 2000).
I go through the process of setting the port, setting the device and doing the download. The download fails, and the apparent error is that the PC can not communicate with the board. I've checked the port, adjusted the baud rates, etc. I've even moved the port number from a high port number (ie COM12) to a lower port (COM2) without any success. I do see activity on the rec/xmt lights on the Arduino board, so some type of data is being sent and received.
I'm looking for:
Someone who has been able to download files from Windows 2000 to the Arduino
or
A way to shim inside the USB driver to be able to watch the traffic going up and down to the board so I can continue to debug this.
or
Some general tips for things to look at in the .inf file that need to be set/not set to make it work on Windows 2000.
I know the boards work I've used them on a different set of Windows XP systems. So I know to some extent the install is good and that most of what I have works.
Full dumps can be found on the Arduino forum, http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1291090110/.
This is the information produced by the AVRDude program while it's trying to download the code.
this could be a long shot, but I jsut recentlz had problems uploading too. Fist of all, how long is the USB cabele you are uploading from? Mine in one case was too long and th arduino woul lose sync. Secondly, and this might just be a silly oversight (like i did) do you have things wired in the digital pin 0 and 1? These are used for the communication, and if there is anything else plugged in to them the upload will also fail.
As I said, long shot but those were two errors I had.
I have an Arduino-based device which connects through USB.
I'd like to detect it from my Qt 4 application, using QExtSerialPort (or whatever necessary), when it's plugged in.
If this weren't possible, I thought I could somehow get a list of the system's port names and just try all of them in search for my Arduino (where I'd implement some kind of handshaking procedure for it to detect it correctly). My concern in this approach is that I'm not sure if a device (for example, printer) would get damaged if I send some kind of handshaking ack at a different baud rate.
So, I don't really know where to start for any of them. Which would be the best approach? How would I implement it?
I believe you can find list of serial ports on Windows by looking into
HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM
registry key
Each serial port on a UNIX system has one or more device files (files in the /dev directory) associated with it:
System Port 1 Port 2
IRIX® /dev/ttyf1 /dev/ttyf2
HP-UX /dev/tty1p0 /dev/tty2p0
Solaris®/SunOS® /dev/ttya /dev/ttyb
Linux® /dev/ttyS0 /dev/ttyS1
Digital UNIX® /dev/tty01 /dev/tty02
more details on serial programing on POSIX systems here
Since your device is USB, your UART port will be emulated by some kind of conversor in his hardware. So first you must understand what driver is being used on your system.
The most common SERIAL->USB conversor uses PL2303/PL2301 chip, so it would create a path on /dev, if its the first device, it will appear as "/dev/ttyUSB0", but you may also see the list reading the proc path (like "cat /proc/bus/usb/devices").
Under Windows it usually creates a virtual "COM", just go to device manager and check the port.
When you are sure about how the HW talks to your system, you may use QExtSerialPort for wrapping the system API and talk to the device.
Way too hard and too platform specific, using weird Windows Registry keys or rely on hard wired device nodes on Linux.
You are on the right way. Get QextSerialPort or QSerialDevice (which I preffer in my projects, because it got integrated in Qt5), have a look at the examples and simply use it. In both libraries you get some kind of port enumerator class which returns you a list of all configures serial ports. Only platform/device specific settings you will have to do manually (like getting RS485 in half-duplex mode on my current embedded project), but "standard" problems are perfectly encapsulated in a QIODevice implementation.
You can use both QextSerialPort and QSerialDevice like a file. Open it (instead of a filename you specify the device name ie. "COM1" on Windows or "/dev/tty0" on Linux, depending on your configuration) and then read or write like you are doing it with an ordinary QFile, QBuffer, Qwhatever-inherits-from-QIODevice.
If you have any problems opening the port and communicating, don't hesitate to ask! :)
