So I recently bought an arduino and when I plug it in it shows up under Ports (COM & LPT), but it doesn't show up under usb devices or under "other devices" as an unknown device. The guide that I'm watching says that it should be popping up as an "unknown device", which I am subsequently supposed to update the drivers for using a specific folder that I installed, but as it's not appearing under an unknown device I am unable to do that. Does anybody have any idea as to what exactly is wrong with my board/how to fix it?
I am not a windows person but I know you have to have a proper driver installed for it to work. Try this link: https://docs.arduino.cc/tutorials/generic/DriverInstallation
See my problem is that the arduino is never appearing under "other devices" like from that guide video. Whether I plug it in or short it it never enters DFU mode, which is what would make it appear under "other devices"
Which guide would that be?
It doesn't have to. Once it shows in Ports (COM & LPT), it's a known device and should work.
Once it's a known device, it will show up in the IDE and you can (should be able to) program the board. The CH340 in the picture is a clone Nano; for that I had to install the generic CH340 driver.
Below screenshot for a Mega (Uno will be similar).
What is the problem that you're trying to solve?
I believe there is nothing wrong. It appears the drivers are already installed. (Windows does that).
You can look at the com port list and assume you board is the comport that is not COM1.
I'm trying to use flip 3.4.7, but for flip to detect the arduino it needs to be put into DFU mode and pop up as an "unknown device", as after it does that I'm able to actually use the correct drivers using the windows update driver function
Is this a genuine UNO or a clone ?
As per earlier post Clones often need a Ch340 driver installed as the USB chip is different .
I'm not too familiar with arduinos but I just bought the one on amazon with the quickest delivery time. I have since installed said drivers from here CH340 Drivers for Windows, Mac and Linux
but still no luck with having the arduino enter DFU mode. tried uninstalling everything and reinstalling it then trying to enter DFU mode, but still no dice
DFU mode?
You're saying that inside the IDE it doesn't list / show-up
Tools / Port / COMxx
I'm trying to do this. When the board enters DFU mode on the window device manager it will appear as an "unknown device", and in turn you're able to use flip 3.4.7 to make windows identify the arduino as "ATmega16U2", and in turn let me run the code that I'm trying to with the board. My problem is no matter how many times I try to make the board enter DFU mode, it always just stays identified under the "PORT (COM & LPT) " instead of becoming an unknown device
O-I-C
I'm recalling another similar subject.
Depending on the revision (Rev.) level, there is a jumper to add and/or 10k resistor to mess with - that's my foggy recollection. And, you have a clone there which makes things "dicier".

I spent two days trying to resolve similar problems, in the end I deleted all the com ports via the registry, and bingo as I plugged each board back in, it was correctly assinged a new com port and was correctly recognized by the Arduino IDE (2.0.0 and 1.1.18). If you are feeling brave, go to " Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Ports" and delete suspect ports. The article that saved me is here.https://theitbros.com/how-to-delete-com-ports-in-use/
Looking at that link you sent my problem is that I can't even get past the "reset the 8u2 or 16u2" step. When I do exactly that, connecting those two pins then disconnecting them, the arduino does not disappear from the list of serial ports. Instead it just returns as if nothing happened
