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.
Screenshot:
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!

I have an issue with Grid-Eye Eval Kit (Panasonic production).
I could not connect it to the PC with USB port. The PC cannot recognize it to perform the application and also COM port.
I have installed USB driver, but no reaction from PC! It seems to have a bootloader on the MCU but I dont know how to solve it.
Anybody has solution for this problem ?
Thank you for helping me.
I could solve my issue, go to this address and download the firmware and download built file into MCU (SAMD21G18A) by microchip studio developer IDE.

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^^
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)
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 am having trouble following the procedure on the Arduino website to update the wifi shield firmware. Here's the link.
The outlined procedure is hard for me to follow, including what files to download from Github and where to store them on my computer.
I then am unsure of exactly what to enter in the command prompt.
Also, the error I was getting in the command prompt is when Opening Port- Fail could not open USB device
This would make me think that I need drivers or something, but nowhere I searched has said this.
I have done lots of searching and I can't find any good tutorials on how to upgrade the wifi shield firmware on a windows computer.
Any help or suggestions would be much appreciated!

I finally figured out how to upgrade the firmware and I documented the process. However, I am unsure of how to post the process that I saved as a pdf and Word document.
1)Make sure that you're connected directly to the shield alone. Do not mount it on anything.
2)Make sure the right driver is installed for the shield. For windows, the driver comes with "Flip". You can find them inside the installed directory.
