So, every time I connect my Moto X to my Windows Laptop via USB, it always keeps plugging and unplugging itself as if I was doing it. The phone icon appears and it begins to try and load the memory storage and then it just vanishes and "unplugs itself". As of now, I just unplug the USB cable from one slot of the laptop and then insert it in another, and it fixes the issue.
Now, that doesn't work either. What's the problem and how can I fix it?
Chances are it's one of a few things.
Bad cable. Bad ports on laptop. Or the port on your phone.
I'd start with some different cables.
Then try a different pc.
If it's the phone, then that's a problem. The phone ports are fragile. My daughters Gtab3 has a wonky port, cause I'm sure the plastic tab was snapped by her using the tablet while it's plugged in. So now to charge it, it will only work sitting still on whatever and I have to jiggle the cable to get it just right. It's only help by the wires inside now.

I repaired the Moto X Device Manager and now I'm using a different cable. So far. so good. I'll report back in a few days to see if anything changes.

So, after messing around with AC Sideload Wonder Machine installing a bunch of apps, something happened and now I can't mount my Captivate to my computer. When I plug the USB into the PC, it momentarily shows "Charging" on BattStatt, but then it goes away immediately and the phone does not show an option to mount nor does it charge the phone.
I have the USB settings set to Mass Storage and USB debugging off. I've tried a different computer and nothing. USB drivers have been installed.
For some reason, it charges the phone if I plug it into the wall.
Did I damage the cable? Did I corrupt some system files? Any advice? Thanks in advance.
Edit: Not rooted, stock android 2.1. I've tried uninstalling/reinstalling the USB drivers. Doesn't help.
Did you try enabling usb debugging again?

Yeah, that doesn't do anything either.
D'oh, just went through this too. Been a while I guess since I'd done it. You have to open the notification bar and select the "copy files for USB" option.

try using another cable, if it doesn't work, look into possibly master reset. If not that, try one click downloader reset.

I just tried another cable on another PC and it sort of works if I jiggle it a bit - I'm able to maintain a connection and transfer files, and it charges as well. I'm starting to think the USB port on the my phone may be defective.
My usb port was a little bent on my phone, after one of my sons tried to disconnect the cable sideways rather than straight. I just adjusted the outer parts very carefully with small pliers, and also bent the inner contact slightly. After that I had no more problems with charging, just be careful! Maybe that could help you, mrpibb?
Also make sure your USB slider door is fully open. It will "click" when fully open or closed.

Yeah, it's fully opened. Using the cable that came with the phone, it never works. Using a different cable, it sometimes works. The weird thing is that it charges fine via AC adapter when its plugged into the wall.

Spitballing here but it might not be the cable but the adapter on the phone.
Pins 1 and 5 (power) might be ok but either pin 2 or 3 (data) could be defective on the phone.

That's my fear as well. I'm screwed?
So I am trying to root my d4 but I wasn't given a stock usb cable. Instead, I am using the usb cable that came with my lg revolution. But when I plug it into my laptop & d4, all of the sudden the phone goes into settings and starts selecting and deselecting settings seemingly at random. Is that something to do with the cable?

Okay, I figured out what was going on. Here's what happened in case any of you experience the same problem:
It was the cable like I was thinking. Sometimes when I hooked the D4 up to the computer with the LG phone's cable, it caused the phone to bog down (maybe it was busy trying to communicate with the laptop and the cable just wasn't compatible so it kept trying and kept trying, etc.). I'd gone into settings to turn USB debugging on and when I swiped along the screen was when it started to lag. So, the D4 couldn't tell that what I'd done was swipe my finger over the screen to scroll down. Instead, it thought I'd selected everything in the path of the finger swipe. But it reacted so slowly I couldn't tell that's what was going on because I'd swiped again resulting in yet more selections/deselections of settings. And then for 20 seconds after swiping it was still catching up and toggling settings on and off. Rinse and repeat...
I borrowed a Motorola cable from a Droid X2 user and everything went smoothly. My phone was recognized, drivers installed, yadda, yadda, and I'm now rooted!

I think it's actually interference created by an unstable DC charging current that messes with the sensitivity of the touchscreen. I have the same problem with my D4 if I use some of the crappier USB wall chargers. I've found the Apple iPhone / iPad chargers work pretty well and most any USB micro cable seems to work pretty well. it could just be less than stellar DC voltage coming from your laptop. Maybe you were running off of battery in one of those instances or maybe wall power, or maybe you were plugged into a different wall socket or at a different house / place with a different mains electrical feed?
Thanks. That sounds plausible. I was using my laptop on every attempt but I don't remember when I was plugged in and when I wasn't. I'll have to experiment a little and see what happens.

I've now tried it in every combination I could think of...connected to a laptop plugged in/not plugged in to the wall, connecting to a desktop...using each cable in each situation, and using a couple of wall chargers. The only thing that made a difference for me was the cable. The moto usb cable works fine as do both the lg and off-brand wall charger cables I have. The problem only comes about when using the lg usb cable with the d4...then stuff gets freaky. No big deal, though. I can easily avoid that combination. Just found it interesting/weird.
I seem to be having problems when I connect my touchpad to my pc. It will not stay connected. I have to move the usb chord around to it hits the right spot and hold it there. I assume this is probably my original usb chord causing the problem. Can anyone recommend an exact model I need to get to replace it? I still have the charger, just need a chord to connect my touchpad to my pc.

Any micro USB cable will work. Most micro USB cables seem fragile and don't have a very long life. I have a pile of them. You can buy them in lots on Ebay for cheap. I suggest getting a few. Also, you can spend a little more and get the flat cables which seem to be a little more robust. You can even get them with LED lights that will tell you when your battery is charged.
Few days ago, I connected my phone to pc while in fastboot and there was a small spark and burnt smell on the USB port. Nothing melted though. Since then, my phone won't connect. The phone still turns on.
Do you guys think that just replacing the USB port on my One will solve the problem?

Assuming you have tried different cables and computer ports, the next thing to look at would be the USB port on the phone.
I think it came with android 12, the card reader is not recognized when plugged in. I have tried 3 of them. They used to work with my S21 Ultra. When I plug them in to my old P30 Pro, they work fine.
Also, I can't connect to my PC as I used to, now the only way is to use DEX.
USB debugging is on.
Any ideas folks?
You say it won't connect to your PC. I assume that means wired USB connection? And when you refer to Dex, I presume you mean you're using is wireless rather than wired?
Assuming those things, it sounds like you have having issues with USB data lines and the common denominator here is your device. My guess is a faulty USB socket or worse, damage to the board itself.
You don't mention charging issues but that would still work if the power lines are OK. Does the phone fast charge? That uses the data lines to provide extra power. If it doesn't then there is definitely a problem with them.
I would suggest this is a hardware fault and would need opening up and servicing or a replacement board. I cant help you with that though. Sorry.
No problems here with cardreaders or connection with PC or monitor with wired Dex connection (SM-G998B on G998BXXU4CVC2).
Suggest you first check your charging port for dust or debris. Clean with compressed (dry) air or gently with toothpick.
no problem with charging......wall socket or in the car.
I don't use fast charging
My little thumb drive still works...just plugged it in. As suggested, blow some compressed air in the USB port.

If the power lines are unaffected then your phone will still charge. Fast charging works by utilising the data lines to increase the power provided. Turn on fast charging (you can switch it off after) and plug your phone in to a wall socket. Does it fast charge? If not then there is definitely an issue with the data lines. This then confirms why connected USB devices don't work. As others have suggested, clean the port and see if it works. If it still doesn't work then it will need to go for repair. Virtually all Samsungs have a secondary board which holds the USB port and bottom speaker. This can be replaced.
