I am having a very bad day. Sometimes I just get overwhelmed by a cascading chain of failures. I don’t know why this happens to me. It must be my fault somehow.

 

I have very little understanding of Android and I don’t use it a lot as I have no smart phone. But I do have an old tablet running 4.1.1 (Jellybean, I think) and I play with that from time to time.

 

Today I needed to take a photo. I don’t take many so I use the tablet for that. It has always worked fine. I have never had problems transferring photos via USB to the pc.

 

Except today. I can’t find any trace of the USB function on the settings menu. It just isn’t there. Somehow I must have deleted it. It is the kind of thing I do.

 

So I tried to see if I could get back whatever was gone. I downloaded UMS Enabler, which has options to enable USB mass storage or MTP mode. I tried both modes. It says whatever mode I choose is working and that USB is connected. The logo changes colour and everything appears to be working. But Windows sees no trace of the tablet. It doesn’t show anything at all, with or without a triangle. The USB cable I am using worked before.

 

This is about as far as my Android know-how takes me. I have no idea what to try next. It worked fine before. Now it doesn’t. I don’t know what I did to it.

 

Any help, as always, will be most gratefully accepted.

Assuming you have wifi and your pc and android tablet are on the same network at home, you could install Airdroid on your tablet fro. Google play store.

This is a really good app. You start Airdroid on your tablet. You don't need to sign into the app - just skip that step.
It will show a link that has a url like http://192.168.1.123:8888 just open a Web browser on your pc and type that address.
The tablet should pop up with a prompt to ok the connection and then your Web browser on your pc should let you poke around the folders on your tablet. You can transfer files etc quite happily both ways.

Yeah I do have wi-fi and I will go that route eventually. I'm just bugged that I had USB working and now I don't. I would like to know what went wrong and how to fix it.

Something about usb debug mode perhaps? I haven't had android for a while now. Is that a branded tablet eg Samsung or some Chinese clone? I've had a clone die on me with weird things no longer working e.g. Google play store suddenly stopped working!

For my $0.02c worth; make sure you have the sound turned up on Windows when you plug your tablet it.  It should make a connection noise in Windows - "Duh-DUNK" (rising in pitch).

 

If you don't hear that, then that points to a physical cable issue (or potentially a driver issue on Windows) as a good place to start more diagnosis / troubleshooting.

Does 4.x have the enable mode requirement on the phone for security? Feel like that was from 5 on but when you connect it and pull down the top menu you can select USB (as it shows up here when plugged into a PC) and then it has your options, you have to change that from Charge Only or something similar to Transfer files.  Again not sure that this was a requirement on 4.x but thought I would mention it.

Thanks for the suggestions everyone. Whatever it is, I can't make sense of. There was always a USB setting on the menu to turn on the port. Now it is gone. I have tried connecting it many times but Windows doesn't register it at all. I have always tried different cables and connectors. I tried a different computer as well as a different port but no difference. Somehow it is just gone. I don't understand it at all.

It turned out to be a cable. Worked fine the last time I used it. This time it didn't do anything. A second one caused the tablet to go into USB mode correctly, but Windows did not see a connection. Third one was a Dynamix I just bought from Cable Direct as a backup specifically for this but it wouldn't plug into the connector, regardless of what I tried. Right cable, right size, but wouldn't go in. 

 

I finally found a fourth one being used for something else. It worked fine. Sheesh.

 

Why do these things always happen to me?

without being accusative, other than luck, how one treats their cable would determine longevity of item?

 ok i take that back - perhaps you meant the connecting pins are buggered - probably means you use plug-unplug often :) they are only made for so many plug-unplugs ...

I get the point but I don't know how I could do this any differently. Two of the cables are used to charge mobile devices. It is normal to plug and unplug them. The Dynamix cable was never used. It was simply faulty. Only one of the four worked.

Ah a couple of points

 

1. There's nothing you can do other than not plug USB in, which, well, when you need to plug you need to plug!

 

2. I find aftermarket cables a bit of a hit and miss - for me, every aftermarket cable I've bought developed issues after 1 week - 1 month of use, such that I'm sick of them now. But then again I have been buying cheap cables. I got what I paid for unfortunately.

Is there any way to test USB cables, eg a device that you can plug both ends of a cable into and it checks that everything is ok?

 

I remember using a little box to test network cables several years ago but I haven't seen anything like this for USB cables.

 

I use a power bank with my phone and I've gone through three cables in the last year because they start off working fine but slowly start failing (probably due to the flexing of the cable that occurs when I'm walking around with the power bank plugged in). At first I suspected the power bank or phone connection but changing the cable always fixes the problem (for a while at least).

I have had so much cable trouble with so many different devices lately. What is the point of making cables at all if they can't make ones that work correctly? I bought an expensive Dynamix cable precisely to avoid this problem, and it didn't work at all. It is very frustrating. I don't have an answer to this. I am also having cable issues with my HDMI monitor and in the recent past I had to replace SATA cables. How in the devil are you supposed to know what works and what doesn't? It is really confusing.
