In Arduino IDE the Port(Tools->Port) is inactive. I'm using Arduino Uno which was working properly. What should I do to fix this problem?
Also there is an error icon next to the name of Arduino Uno in windows Device Manager ( Error code in device manager: "This device cannot start. (Code 10)" ).
I uninstalled and updated the driver but nothing happened.
Any help will be appropriated!
The problem is solved here. You basically need to download and install the CH340 USB driver.
I downloaded it from this link and it worked pretty well.

I'm trying to use an Arduino board (brand new), but it doesn't show up as an available port to write to connect to. Under my boards it doesn't show up, but it shows up under "Other Devices" as "ATmega16u2 DFU"
I've read online that the firmware needs to be updated, and I followed the instructions on the following link:
https://www.arduino.cc/en/Hacking/DFUProgramming8U2
The link to the latest firmware is broken. How else can I go about this?
Have you installed the drivers? if it is an original arduino board, inside the IDE installation folders you will find the drivers.
After I searched for this issue and did not find a solution yet, I will ask here:
I have a Windows 10 computer with Arduino IDE 1.8.5 installed.
When I try to connect my Arduino Industrial 101, it is not possible to select the COM port in the IDE. Additionally, it isn't even shown in the device manager as "unknown device" as e.g. Arduino COM port doesn't work or Arduino doesn't get recognized state.
Before anyone asks:
-I ran the installer as administrator
-The device drivers are installed (At least they were ticked in the installer programm)
-I have this issue on a second computer (Windows 7 with Arduino IDE 1.8.5), too
Does anyone have a solution for this issue?
EDIT: I tried again with the NodeMCU: The IDE shows COM port 7 in the information area on the lower right but when uploading I get a "Failed to open COM7" error. So, it seems to be a general IDE issue...
Ok, I found the issue... You won't believe me but either it was a broken cable or a cable that does not have enough power supply somehow. Strangely, this was the official cable from the Arduino package I got. My Samsung mobile cable saved the day^^
Getting this when I upload the blink example from the arduino getting started book. The file compiles but just hangs at this point. I have reset, restarted, reinstalled. Nothing seems to work.
It worked just 1 day ago and there have been no changes since.
System wide configuration file is "C:\Program Files (x86)\Arduino/hardware/tools/avr/etc/avrdude.conf"
Using Port : COM5
Using Programmer : avr109
Overriding Baud Rate : 57600
Most of the problems with uploading sketches to Arduino boards come down to communication problems.
Try using other USB ports, check if you selected the correct COM port in the Arduino IDE, also check that you selected the correct board in the IDE.
If all else fails, please check if you can upload the sketch on another PC.
this error might be caused from a mistake in connecting the wires or a problem in the program.So try to check the connection of the wires and if you uploaded the program just because you still don't know how to write arduino codes, I advise you to learn and experiment with the help of the tutorials on the arduino site and reference.I hope that my answer helped you.
I am trying to download code to my littleBits Arduino module on IDE software. I am not able to find the port whenever I am trying to download the image to the board. Is this an internal issue, or an issue with my Arduino board?
You need to check if the arduino serial driver is properly installed in device manager. If arduino serial port is available in Ports then you can download program through IDE

Make sure you have proper drivers for your board. In Arduino IDE make sure you are selecting the proper target ie, littleBits Arduino board.
If you are using the Linux system you can use dmesg to see if your system detected the device properly.
If you are using windows system use device manager to make sure your device is properly connected.
Has it ever worked? Did it work for a while then stop?
Reason I ask, I had a problem where the Little Bit suddenly stopped accepting new code. Whenever I tried to download, the Arduino IDE started reporting Unknown USB Device.
Turned out, we had bricked the device. I blogged my steps for recovery here.
Check tools>ports and see if any are available, try them all, (check
while the board is connected)
if none are available check device manager under com ports there should be your device listed if not the you need to reinstall the drivers.
also check if the board is connected correctly (i.e. the connection cord is working properly)
I am trying to connect a esp8266 wi-fi module via a usb ttl converter to PC, but the device manager is not showing any well established port for the given connection. The only thing device manager shows out is a "CP2102 USB to UART Bridge Controller" and hence Putty is not identifying the port.
Kindly help me out.

First of all you need to install the drivers from here: https://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
Then you need to make sure your power supply for the ESP8266 has an output of 3.3v.
You need to re-download the latest driver.
Mine was working perfectly fine for about 4 months and then out of nowhere it stopped working. (I suspect it stopped working because of some windows updates I did on my machine.)
I tried reinstalling with an older .exe install file and it wasn't solved. It wasn't until I actually re-downloaded the file again (from https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers) and then it worked!
Hope this helps!
