Hello,
Hope someone can help.
Strange thing here, probably I'm missing something
New PC (to Arduino, running strong for almost a year). Wanted to install Arduino UNO with 3 motor shield V2 (used on another computer without any problem).
Installed IDE, but it is not recognized, not as UNO without a driver, just USB serial 2.0.
Update driver, select folder, but can't chose arduino.inf, just the folder and windows don't find the driver.
Any ideas on how to proceed?
Thanks!!
I have downloaded and installed this one... now it is recognized by SimHub...
I Will let you know if it works...
BTW the CH340 link under the thread that is at the beginning, does not work..

Thanks for pointing this out. I have observed this problem of the website of the CH340, wch.cn, being down some months ago. I was hoping it would come back, but now it's looking like that's not going to happen.
I think it's important to get drivers from a trustworthy source. This is why I have always recommended people to go straight to the manufacturer's website to get the CH340 driver. Since that's no longer possible, I have two alternative sources I'm considering:
The first is SparkFun's tutorial dedicated to the CH340:
https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers/all#drivers-if-you-need-them
SparkFun is definitely a trustworthy source, and that is a nice tutorial as well. The only problem is they are providing the outdated 3.4 version of the Windows driver (I didn't check to see what the situation is for the Linux and macOS driver versions). The latest version from the manufacturer is 3.5, with a 2019-01-30 date, as compared to the 2016-09-27 date specified for the SparkFun 3.4 download.
The second is the archived copy of the manufacturer's website on the Internet Archive's Wayback Machine, trustworthy both because it's provided by Internet Archive and because it's a copy of the manufacturer's own website. This provides access to the latest version of the driver (3.5). The main problem with this is there is something about the wch.cn website that makes the download links from the archived driver page not work:
CH341SER.EXE - 南京沁恒微电子股份有限公司
however, I found that the archived copies of the downloads themselves work fine:
Wayback Machine
I am leaning toward archive.org as the best source, but am interested in the opinions of @rolofuentes and any other forum members.
I found this working link on Seeed Studio site

The driver that I have downloaded work, Uno is now detected, by IDE and SimHub. Somehow The 3 motor shield V2 I have installed is not recognized/working. Can't find if it is a hardware problem or a software problem (or the problem is just me doing something wrong).
Making hardware changes is a bit difficult for how my sim rig is constructed, but until now I know everything is powered, no pins missing, and if I press the reset button of any of the motor shields, the whole Arduino system reset, so this makes me think that they are all connected and working...
Also, I have tried the IDE example (running the motors) and it also doesn't work (but the code is uploaded to the UNO (this makes me think the Driver is working OK)
This is slow.. I have to go ceteris paribus on the try and error path..
Any ideas on how to solve this are welcome!
Now working... was just a problem between the seat and the keyboard... as always right??

http://www.wch.cn/download/CH341SER_ZIP.html
The one in the "Please check the troubleshooting guide before posting here." post, and the link I have always recommended are the equivalents to that, except they point to the page for the .exe version of the driver package instead of the .zip.
Despite many attempts to load the pages of wch.cn (including that .zip file page) while I was investigating the issue, it was not working for me earlier today, and also not working the last time I checked it some months ago. But it is working now so I guess it must have been somewhat coincidental that it was out both the previous times (though it also likely indicates that the site's availability is unreliable).
So I think it's best to leave the link as is, but I'm already on alert as whether the uptime of this website is too low to make it a viable source for the drivers.

The driver that I have downloaded work
I understood that, but I'm not going to feel comfortable recommending people to install a driver from "geekfactory.mx". Don't get me wrong, I have no reason to believe the good folks at geekfactory are unreliable, but I need to take special caution when recommending people to install software. That both because I don't want to be responsible for anyone getting hacked, but also because people are going to be suspicious (rightly so!) of some random person on a forum recommending they install something. If the source I am recommending is trusted by people, then they don't need to worry about whether I'm trustworthy. But if the source is unknown to them, they will need to trust me.
This is why I was interested in your perspective on the matter of which of the two URLs you would feel more comfortable installing a driver from on the advice of a random stranger on the Internet.
You are 100% right...
What I mean is that the drive that I downloaded was working fine, the problem was me.
But also, I did install this one (before I notice the problem was me):
https://web.archive.org/web/20210119102158/http://www.wch.cn/downloads/file/65.html
Now it running without any problems... Actually, I'm using that one!!
I usually feel more comfortable with .org sites...
Sorry for the misunderstood.
