Arduino Uno is not showing up at all anywhere is the PC (including device manager or "devices and printers" when connected via usb cable. As a result it is not showing up in the IDE as well as working port. Tried reinstalling the IDE and still it wasn't working. I suppose this is a common problem but none of the fixes seem to be working.
I had loaded a program onto the Arduino Uno and it is still working but not being detected by PC. Please help me with this problem.
The most common cause of the board not showing up even in Device Manager is using a defective or charge-only USB cable. Try verifying your cable works for data on another device or use a new cable.
It's also possible you damaged your Uno since the time of the successful upload.
What OS ?
What type of USB port ?
I am using the USB cable which came along with the uno. It has been running perfectly since it was bought. I connected a nano via a miniUSB cable and it works perfectly fine. SO the problem is with either the cable or the Uno. Uno is performing the stored program though.
Having the same problem with Arduino MKR 1010. It does not Work in MAc or Windows and I am using a cable that worked with an ESP32 board.

This is an Arduino issue and not a cable issue. Sometimes it works and sometimes it doesn't not.
"Sometimes it works and sometimes it doesn't not" could definitely be caused by a damaged cable.

I can't share this view. In my daily environment as a teacher in an Informatics department I am dealing with this SoC, e.g. Raspberry Pi (all kinds), ESP8266, ESP32, Smartphone (e.g. HTC, Samsung and Cubot) so many times and with high quality cables (not low cost ones) and the only devices that have USB connectivity issues are the Arduino ones.
In addition to that how can you explain the fact that the same cable that is working perfectly with my Arduino Yún becomes suddenly so bald quality that I can't connect my device any more and then after some months the same Arduino device with the same USB cable works fine. Even worst the cable that is not suitable for one Arduino Yún works perfectly with the other one.
We have been discussing this with your support services in the past. I did order 2 pieces Arduino Yún and the vendor (PlayZone.ch) in Switzerland sent me replacement pieces 2 times under guaranty. The last time he wrote that he will refund me and wont sell me those devices anymore.
I think you must admit that your devices have USB stability issues and should solve the issue. The issue seems to be due to an over current situation.
He is a more specific Linux log when connecting the Arduino Yún device. It doesn't matter which USB cable I use the message remains the same.

I find your devices very good from the simplicity and clever design, but because of this issue and I can't use these reliably in my labs experimentation.

An even better input for your investigation. My purpose is to help fixing the issue.
Still under the same Linux environment, the same USB cable and with the same 2 Arduino Yún (1st and 2nd).
Here is the Linux system log.
According to this and my understanding, the issue lies within the 1st Arduino Yún USB connection and not in the USB cable itself.

You seem to be under the impression I'm a representative of the Arduino company. This is not true. I'm just a hobbyist who tries to help people out on the forum. I don't officially represent Arduino in any way. It's very rare for an Arduino employee to comment on the posts in the general forum sections. If you need to talk to someone from Arduino about an official Arduino product, you can use the Store Support Contact Form:
Just my two cents here.
My YUN went through a period of work / no work.
Slightly and gently moving the connector on the cable sometimes resolved the issue or at least made the required connection to get the board to fire up.
Eventually I checked the connector on the board and found there were dry joints.
A very fine tipped soldering iron and a small amount of extra solder on all the connections including the support connections fixed it almost completely.
I have to add that this was a DOT ORG board and NOT a DOT CC board.
I also found during all that messing around that there can be slight differences in the ends of the USB cable themselves and that after repeated use they can also be part of the cause. Upgraded the micro connector cable and no longer have any issues at all.
I've definitely had the problem of a USB cable that works fine for many other devices not working on one particular device. I have a big pile of USB cables so I just try a couple different ones until I find one the device likes.

I am sorry for that. You're right. Please, accept my apologize.
No need to apologize. I just want to make sure that my actions don't reflect on the Arduino organization.
I'd expect a different level of support from customer service than from a volunteer doing it as a hobby. In my business, I take the attitude "the customer is always right" and make sure every problems is completely resolved. As a volunteer, I try to help when I can but I don't feel the obligation to solve every problem. Sometimes I get busy or bored and just hope someone else will be able to help where I couldn't. I currently have a backlog of >2000 forum threads I saved because they were of interest to me but I didn't have time for. I'm not sure when I'll ever get around to going back through all that and by the time I do it will likely be too late for it to help the person posting (though it's still worth resolving problems so others won't have the same trouble). I think we do fairly well here on the forum but certainly there are a lot of threads that never get resolved.
Hi all,
The first arduino I received came with a defect. I just received a new one working.
The on led is always on now.

I am happy for you. You've been a lucky guy.
I do however think that you haven't got my whole story

Check this web site and make your own opinion: https://www.arduino.cc/en/Guide/YunUpdater
How can you loose the the warranty if you make a firmware upgrade according to the manufacturer's indications? Quite surprising... isn't it?
Once again, you have been lucky and I haven't.
