Sorry if this isn't the right place to ask, I'm new to arduino and I searched for my question here on ST and found similar but outdated queries that didn't help me so I might as well help others who might be having the same problem.
The very first time I connected arduino to my W7 laptop, it worked like a charm, installed new device drivers successfully, uploaded my sketch (which still continues to run every time its powered). I checked device manager and it showed the arduino under COM/LPT ports.
Then, after disconnecting the arduino and reconnecting, it no longer shows a COM/LPT section and instead shows an unknown device under USB. Every time I've tried uninstalling driver and reconnecting, it keeps giving me a driver installation failed error.
Googling for the issue told me to "update drivers" manually using the .inf provided with the Arduino installation through device manager, but when I tried that, it says the drivers aren't compatible with Windows x64.
Another tip from an arduino forum user told me to copy the arduino.inf into C:/Windows/inf, but that didn't solve the problem either
Any ideas?

I've been using a STM32H753I-EVAL2 board for several months now.
Last week I was suddenly not able to connect to the board anymore (tried with several tools: GDB, STM32cubeProgrammer, always same message like "STLink error"). I of course checked the driver was correctly installed and was the right one, reinstalled it, changed USB cable and ports. Also tried to connect to a Nucleo which was fine.
I randomly tried to change the power supply of the board from PSU (ie. powering through external power supply) to STLink (powering through USB) and it solved the issue. I was happy as I thought it was just a hardware issue like a conflict between both power supplies.
But today the board was not connecting anymore again. So I switched back the alim to PSU and it worked !
Did someone experience the same issue ? Or does it trigger something for someone ?
I'm using an Arduino Leonardo. It worked very well the last time, but now my Computer (Win 10) doesn't recognize it anymore. (I used Win 10 before too).
After pressing the "reset-button" it works for a few seconds, but after that it's gone again.
Do you have any ideas, how I can solve this problem?
Reinstall the Leonardo driver.
change the usb wire.
if it is not worke then the boot loader got corrupted.

My laptop model is SW3-16-15TV, I installed windows 10 home on it and I don't have sound, wi-fi, and other features... I found drivers for it here https://www.acer.com/ac/en/US/content/support-product/6460?b=1 . I download only this driver https://i.stack.imgur.com/8JXTL.png because contains all other drivers. I tried to install other drivers one by one but I can't. Some of them throw errors and some of them installed but nothing happend. For example I installed audio driver, but after I reboot my pc I don't have sound and the same problem. I entered in BIOS and from there I found laptop serial number and searched that drivers... When I want to run Platform Drivers Installer it throw me this error:
a system reboot is required to rollback changes made
I didn't know why it throw me this error :(
I found the how to fix drivers! Device Manager -> uninstalled driver (with yellow or red attention sign). Click on Browse my computer for... -> Browse driver path, check that checkbox and click Next !
my external monitor stopped working today after restart. I found the computer on during the night. Running win 10 64b on Lenovo U430p.
The monitor worked fine the whole time. I can see windows logo while booting, but then it says no signal. When I uninstalled the video driver it worked (login screen, desktop, res 800*600), until windows installed driver over it. I tried getting newest driver from both Lenovo and Intel, but with no results.
Did anyone experience this issue as well? I read about people having this with new computer but not to happen from the blue and ususally at least disabling the video adapter helped.
Thanks!
Haven't found real solution and it seems to be a problem of Intel graphic cards.
However reverting to most basic driver windows can offer did the trick
Uninstall driver
Rollback driver
Using wushowhide.diagcab utility (https://support.microsoft.com/en-us/kb/3073930) disable updates for all video card drivers
I bought my Arduino Uno R3 a few months ago. It's been working like a charm since then, but today, it stopped interfacing with my computer. Let me be more specific. I have a 2013 Macbook Pro Retina with OS X 10.9 (Mavericks). It has the latest Arduino IDE installed.
I was using it today and after uploading a simple sketch (it worked for a little while) my Mac stopped recognizing it, and since, I haven't been able to access it. The LED connected to Pin 13 stays on 100% of the time. The RX/TX LEDs don't flash, but the main functions of my sketch (other than the serial functions).
Have I screwed my Arduino's Serial chip? What can I do? I am only 15, so another $30 is a little bit too much to spend to get another one.... :)
Thanks!!
UPDATE: I forgot to mention that I have tried my other Windows computer, and another cable, just to rule out those possibilities.
That is a very common issue with Arduino. I used to face that problem all the time while using Arduino. Though I never really found a solution for this, the problem did go away after sometime. Did you try resetting the uC using the reset button on the board, or restarting the IDE or your system if neither worked?
Make sure you have chosen the right COM port. On a windows system you can do this by going to device manager and look for the ports tab under it.
