Arduino Usb Port Driver Download

[Oliverio Gallman]

Idownloaded ch40 and ftdi drivers for Arduino Uno but the port option is grayed out everytime. I cannot find any things on the web for this problem. I programmed the same Arduino Uno on a laptop and it was working fine!! I didn't Even installed any drivers in the laptop. But on my desktop computer, i installed every drivers but it's just not working!!!! Pls help

OK, that is the ATmega16U2. Its drivers are in the drivers subfolder of the Arduino IDE installation folder. Try pointing the Device Manager driver installation wizard at that folder to see whether it will install the driver. After that, it should show up in the "Ports (COM & LPT)" section of Device Manager.

I did the same thing, but it says "Windows was unable to install drivers for your "Unknown device". And also now when I plug the Arduino Uno r3 and open device manager, it appears under the "Universal serial Bus" list. And my Uno r3 is shown as "unknown device(device descriptor request failed)" something like this is shown. The problem is getting worser. Pls help

I want to provide some pre-flashed arduinos to some tech-nots and I want their experience to be as easy/smooth as possible. They don't need to modify the sketch but the nature of the application requires a PC to communicate back and forth with the arduino.

Well installing the IDE does not install any USB drivers automatically as the IDE does not know at installation time what kind of arduino board you may have or how many different types of arduino boards you may add in the future. Installing the IDE does result in all the various drivers being placed in a folder, but the actual installation of the drivers is a manual process that one has to go through when they first plug a arduino board into their PC.

So for non-tech types I would think having then install the whole arduino IDE just to have access to the usb driver files would be complex for them. Assuming you know ahead of time what flavor arduino board they will be using, you could just send them the correct USB driver file in a cheap memory stick or just email it to them?

I will know exactly what boards I give them (probably an Uno). If I wanted to give them the uno driver, what do I need to give them and tell them to do? Unfortunately they'll be running on anything from Win8 to WindowsXP...

Installing drivers for the Arduino Uno or Arduino Mega 2560 with Windows7, Vista, or XP:

Plug in your board and wait for Windows to begin it's driver installation process. After a few moments, the process will fail, despite its best efforts

Click on the Start Menu, and open up the Control Panel.

While in the Control Panel, navigate to System and Security. Next, click on System. Once the System window is up, open the Device Manager.

Look under Ports (COM & LPT). You should see an open port named "Arduino UNO (COMxx)"

Right click on the "Arduino UNO (COmxx)" port and choose the "Update Driver Software" option.

Next, choose the "Browse my computer for Driver software" option.

Finally, navigate to and select the driver file named "arduino.inf", located in the "Drivers" folder of the Arduino Software download (not the "FTDI USB Drivers" sub-directory). If you are using an old version of the IDE (1.0.3 or older), choose the Uno's driver file named "Arduino UNO.inf"

Windows will finish up the driver installation from there.

Installing drivers for the Arduino Duemilanove, Nano, or Diecimila with Windows7, Vista, or XP:

When you connect the board, Windows should initiate the driver installation process (if you haven't used the computer with an Arduino board before).

On Windows Vista, the driver should be automatically downloaded and installed. (Really, it works!)

On Windows XP, the Add New Hardware wizard will open:

When asked Can Windows connect to Windows Update to search for software? select No, not this time. Click next.

Select Install from a list or specified location (Advanced) and click next.

Make sure that Search for the best driver in these locations is checked; uncheck Search removable media; check Include this location in the search and browse to the drivers/FTDI USB Drivers directory of the Arduino distribution. (The latest version of the drivers can be found on the FTDI website.) Click next.

The wizard will search for the driver and then tell you that a "USB Serial Converter" was found. Click finish.

The new hardware wizard will appear again. Go through the same steps and select the same options and location to search. This time, a "USB Serial Port" will be found.

You can check that the drivers have been installed by opening the Windows Device Mananger (in the Hardware tab of System control panel). Look for a "USB Serial Port" in the Ports section; that's the Arduino board.

Yeah I've seen the getting started page. It's too much for the people I want to give this to. I was hoping either to find or write something that would do it automagically for them. So the guide would look like this:

My tech-nots can handle that... I guess what I'm curious about is that on my Win7 machine I plugged the board in and installed the IDE. That's it. Did I get away with that because my win7 install didn't need a driver install?

I can't really answer that not being a Windows software guru type. I started with arduino back in the version 7 or 8 IDE days I think, and once your PC already has the needed USB drivers installed, upgrading the IDE does not require reinstalling USB drivers if you already have them installed into your machine. I did recently get a new computer with windows 8.1 and spend a lot of time on the web finding the work around of installing 'unsigned' drivers for FTDI, USBasp programmer, USBtiny USB driver, etc. but in the end it got done, abet with a lot of time and frustration on my part.

I do appreciate your problem/objective and a simple standalone .exe installation of arduino USB drivers would be a nice thing to have in ones 'tool box' if it is indeed possible. But keep in mind that the arduino platform supports multiple OSs and they have to publish installation instruction to support so many different PC, OS versions, and board types that it's hard to see how to simplify the process for just a subset of user's needs. But again there are gurus around here so maybe someone can help you with your desired objective.

The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter.

The cable that shipped with my Arduino Uno worked for power but not data transmission so the /dev/tty.usbmodem was not showing up in the Tools --> Port menu. After I switched to a different cable, the /dev/tty.usbmodem port showed up and it worked beautifully.

Yosemite 10.9 (and OS X 10.10 and newer) requires a signed USB driver kext (kernel extension). You can find one on the FTDI web site here:

Use version 2.3 for 64-bit OS X 10.9 or later. Install and reboot.

This exact same thing happen to me on my mac running the same operating system. I had to restart this system a few times to get it to work. I restarted it with the arduino plugged in; and that worked rather than my previous attempts when i rebooted then plugged in.

After an awkward, google searching beginning, where the board only accepted a new sketch after being physically unplugged and replugged, I downloaded the latest FTDI driver, installed, and RESTARTED the mac. Now, joy and peace reigns. No side-effects with other mac functions, thankfully. Hope this helps.

The CP210x USB to UART Bridge Virtual COM Port (VCP) drivers are required for device operation as a Virtual COM Port to facilitate host communication with CP210x products. These devices can also interface to a host using the direct access driver.

The CP210x Manufacturing DLL and Runtime DLL have been updated and must be used with v 6.0 and later of the CP210x Windows VCP Driver. Application Note Software downloads affected are AN144SW.zip, AN205SW.zip and AN223SW.zip. If you are using a 5.x driver and need support you can download Legacy OS Software.

To add to Nikhil Borle's answer, if you check the USB Devices in the System Report and don't see anything, you may have a cable problem. I didn't see my device, and found out that the USB Type-B cable wasn't fully plugged in to my Arduino! (It has been a very long time since I've used Type-B). Apparently it's possible to plug it in halfway and it will still receive power, but won't be able to communicate...

Once I fixed that, I closed & reopened System Information and it showed up as simply "Communication Device", although when I selected that, under the details, "Manufacturer" was listed as "Arduino (www.arduino.cc)" (I've got an Arduino Uno R3).

I had the same issue with Arduino Leonardo knock off on OS X Ventura on an M1 MacBook Pro. When plugging in the board into USB I noticed some UI window appearing and disappearing quickly. Too quick to identify what is it. Leonardo appeared in System Report, but not in Arduino IDE.

I had a similar problem with Arduino Uno and Mac Catalina 10.15.7. After try multiple solutions I noticed the green on light on my Uno was very faint or kept turning off. After playing with the board for a minute I unplugged all the wires for my project so that only the USB cable was plugged into the Uno and nothing else. After that the Arduino showed in the port menu as expected.
