When I try to upload my programme on the Arduino Uno Chinese clone, It says

                                  -> avrdude: ser_open(): can't open device "/dev/ttyUSB0": No such file or directory ioctl("TIOCMGET"): Inappropriate ioctl for device
  • My Arduino Programmer: ArduinoISP
  • My Arduino Software version: one.6.8
  • My Bone: Linux Mint

Can you assistance me prepare this error?

  • What is the serial port of your arduino?

    May 12, 2016 at vii:51

  • My Serial port is /dev/ttyUSB0 . I am using Linux Mint .

    May 12, 2016 at 7:53

  • if you do ls /dev/ttyUSB0 does it show something? If and so, are you a member of the dialout group_

    May 12, 2016 at 8:53

  • Run from a final: test -westward /dev/ttyUSB0 || repeat Error - if it tells you Error y'all don't accept permission to access the device. If information technology tells you nothing and so your permissions are fine.

  • @frarugi87, when I type 'ls /dev/ttyUSB0' , it shows me a message -> /dev/ttyUSB0

This could exist whatsoever number of dissimilar issues. Here are several mutual causes:

  1. Yous have multiple USB serial port devices continued to your computer. Try using the command ls -l /dev/ttyUSB* to check if your computer thinks in that location are more than than 1 concluding USB device. Disconnect all of them, then simply connect the Arduino Uno. Then repeat the check.

  2. Yous exercise non have permissions. This is tricky to bank check equally Linux offers a flexible merely complicated root, group and user permission prototype. You lot should NOT make a addiction of this, simply, for a quick check, yous tin try running the Arduino application every bit root and bank check if you lot tin can upload a sketch to the Arduino Uno.

  3. You have a counterfeit FTDI scrap on your Arduino Uno that has been rendered useless by sure versions of the Windows FTDI Commuter. The USB IDs tin become reset to useless values. I believe the electric current FTDI Windows Driver no longer does this.

  4. You did not install the Linux FTDI driver. A driver is a program to abstract the hardware from the application. In this way, different hardware can be treated the same by the awarding, simplifying the awarding. However, the wrong driver/hardware combination may not work every bit expected.

  • FTDI drivers are not a separately installed particular on well-nigh Linux distributions in the way they are with Windows. Generally they would only need to be manually added to a very odd Linux such as might exist found on an embedded or special purpose system or a custom build from scratch - the code has been part of the kernel source effectively forever and will be built and shipped as an automatically loading module in any ordinary full-featured Linux.

  • Don't run arduino IDE as root to test if permissions is at fault hither. Run this command instead: sudo chown root:YOURUSERNAME /dev/ttyUSB0 to give yourself access to the tty device

I had the aforementioned trouble and solved with the proposition of ndemou:

                  sudo chown root:YOURUSERNAME /dev/ttyUSB0

  • This is a bad idea, in particular on a typical dynamically configured linux with udev or like managing /dev nodes you will have to do it every fourth dimension yous connect the device. Add together your user to the appropriate group instead, which is a lasting set up.

  • @Greenonline - delight don't brand trivial edits of bad answers.

  • @ChrisStratton - Please, kindly refer to the Review Queue.

  • That means absolutely zero. This is a fundamentally bad answer, and that fact cannot be changed by format editing. Additionally, even if this were a good answer, your edit would exist pointless. Such pointless edits waste everyone's fourth dimension. Kindly desist.
