I removed the kext and pkg files for the FTDI drivers and deleted them completely, still when I open the System Report I still see the FTDI USB Serial Driver entry.
Use the USB / Serial CH340 / CH341 Driver‘s Download: Windows 32 bit : Download. But dont worry, Srishti Robotics have provided two drivers. Because Arduino Uno Clone does not use the same driver chip with Arduino Uno R3 Original. Most new users find it difficult to get the USB drivers. Now even after doing all this when I connect my Arduino Uno to my Mac via the USB it does not get detected. Arduino Uno R3 Clone CH340 / CH341 USB driver. So I removed the FTDI drivers from my Mac so it will use Apple's drivers. He suggested we remove the FTDI drivers and rely on Apple's drivers. Revision 2 of the Mega 2560 board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode. Instead, it features the ATmega16U2 (ATmega8U2 in the revision 1 and revision 2 Arduino boards) programmed as a USB-to-serial converter. Then I came across this post: where the user is having this same problem with MacOS Sierra. The Mega 2560 does not use the FTDI USB-to-serial driver chip used in past designs.
I followed this link : where it tells us to download and install the FTDI drivers separately. I updated my OS to Sierra 10.12.5 and now suddenly the usb serial option has disappeared. Power LED is constantly on and L LED is flashing in a specific pattern.Few weeks ago my Arduino Uno (IDE version 1.8.2) detected the USB port and I was able to do some small IOT projects. Here's the video footage when the device is plugged in. Arduino not getting detected, USB2.0-Serial issue Since Arduino hardware is open source, it is manufactured and marketed by different vendors. But don't worry, Srishti Robotics have provided two drivers.
I have also tried to put the device in DFU mode by shortening RESET and GND next to Mega8U2 chip in order to try to upload a new firmware. Most new users find it difficult to get the USB drivers. If that fails you might have fried your Arduino's USB chip (or some other hardware on the Arduino). If that fails reinstall the Arduino USB driver and repeat above. If that fails reboot your machine and repeat the above. Learn how add library to your Arduino IDE. Also try plugging it into a different USB port (if no ports are displayed) and it should register with a new COM. Because of this, I am unable to get to the point to install the drivers for it. Libraries are certain codes that work for specific hardware or sensors. The device is not listed in Device Manager and Windows does not produce the sound when connecting plug-and-play device. Using different cables (including the one that works with my printer).
Switching to other USB ports on my computer.
My operating system is Windows 7 圆4 and here are the steps that I tried: Do the characters appear on the screen as if typed at a keyboard Look in Device Manager. Read a card or key fob by passing the card or key fob on or near the reader. Does it work without installing drivers Open any editor such as NotePad.
I am having problems connecting it to my computer and have spent several hours trying to figure it out to no avail. How to use USB RFID readers on an Arduino Uno. This is a Chinese product and should be the exact copy of Arduino.
