Arduino ide port greyed out12/6/2023 Look on the internet for ways to release them. ![]() Windows users, feel free to pick this apart.Windows will reserve ports (based on VID and PID of the USB device I think) and sometimes that can become confusing. It's a fair bet that if you had to manually install a driver in device manager for a device that did not exist in the first place, you're probably not using the right driver.Īfter all this, if you manage to get the right driver installed and the hardware is clearly recognized, you might just need to run the arduino IDE as administrator so it has permission to talk to the com port. I think the most common UART that clones use is the ch340 - so you might just be able to grab this driver and things will start working. Also: I think it's possible for a device to be "disabled" in windows, which might(?) prevent it from showing up in device manager, but from the docs it looks like devcon should show disabled usb devices.Īssuming you find the usb device id of the Uno or Uno Clone's USB UART, you'll need to hunt down its driver by googling that device id. If all else fails, it looks like you can use a microsoft utility called devcon ( devcon hwids =usb) to list usb devices. Googling "lsusb equivilent windows" leads me to believe that you can open "device manager -> details -> by path" and specifically look at devices attached to your usb hub. The first thing I'd do is unplug the device, run lsusb then plug it in and see if running lsusb again lists a new device. I'm a linux user, so I'm approaching this from the angle of how I'd start debugging it. Next step is to go back over to buddy's house and plug the same uno into his machine to see if it works, but i won't have time for a few weeks. ![]() i'm also not the most tech savvy guy on the planet so i'm not sure if that means anything. in fact i had to manually go in and "add legacy hardware" in order to get the ports (com and lpt) option to appear. ![]() is it possible the uno itself is bad?Ī few other things to note.when i have device manager open and i plug-in/remove the usb cable, nothing appears/disappears. The uno board does light up when i plug it in, but my computer doesn't seem to be recognizing it. bought new cord, no luck.ģ) drivers.went into device manager and manually updated the drivers, making sure it was looking in the right folderĤ) found a random troubleshooting tip online that had me go into the preferences.txt file and manually add the COM number that appeared in my device manager i'm not as familiar with iOS so i didn't do much else to get that to work.Ģ) thought since it wasn't working on wife's mac, could be a bad cord. i have only one port option but i don't think it's the right one. a list of things i've tried:ġ) went to wife's mac and downloaded the iOS IDE. i plugged it in and downloaded the IDE from, and have never had an option to select a port. ![]() (it says made in italy, also says atmega328P). It doesn't appear to be the chinese knockoff, although admittedly i'm not entirely sure how to tell. A buddy of mine gave me his old arduino uno starter kit that he purchased from a radio shack a few years ago. I'm brand new to this, started researching about a month ago and finally decided to give it a shot. Seems to be a common problem but i've been working to get it resolved for over a week.
