Usb connection doesn't always work - T-Mobile, Samsung Galaxy SIII

Ok so here is the story so far. If I connect my galaxy s3 with the factory cable directly to USB it works fine.. however the cable is too short. so I bought an extension. Its a male to female (good quality) and I connect my factory cable to it. My computer says usb not detected most of the time with the longer cable but if I unplug it and plug it back in and then switch between the media device (mtp) and the camera (ptp) a few times, it will work. Once it connects, it works fine for transferring songs/movie files/whatever. Any clue why this does this? Its super annoying for it to not just connect the first time.

pc doesn't detect usb connection/sync

Hi,
I bought an used Dash and when I try to sync it through ActiveSync nothing happens. I tried to intiate the sync from the Dash and nothing happens either.
Basically, nothing happens when I connect it to the USB port in the PC. It doesn't try to sync, the PC doesn't see a new unit or anything else that happens when you connect something to the USB. I used to have another Dash sync'd to the same computer and everything was fine.
Is it possible that the usb port in this Dash is broken? is there any way to verify it? I've tried with two different cables that I know they work and plugging it in different USB ports in the PC.
Thanks.

PD: the Dash does charge through the usb cable. And after charging for a bit, I can see that the battery is full, led is green.

Check this:
on the dash
Start menu
Settings
Connections
More
USB to PC
remove the check-box in the advanced connection setting
save and try again
also... are you running a firewall? if so, that's quite likely a problem as well. i run comodo and it blocks the connection. i haven't figured out the proper setting yet to allow the phone through so i just shut comodo off when i'm needing to access the phone from my computer.
When you plug your usb cable into your phone, does the light on the top turn either amber or green? If so, usb connection is working. If it is still not syncing, open Activesync on your PC got to tools-connectionsettings and make sure Allow usb connections is checked.

PC Connection Issues with EVO

Already tried reformatting Windows and installing any and all drivers I could find.
When I connect my EVO to my PC via the USB cable, the connection type window appears, the amber light turns on, and it shows up on my PC for ~2 seconds. Then it disappears. I have been unable to keep it connected.
It works on other PCs I've tried, just not mine for some odd reason. (Any other USB item works fine), and I've tried multiple USB ports.
Any ideas?
I had this exact issue when I was going through a non-powered USB hub. As soon as I plugged it into my computer's direct USB plug no issues. How old is the computer you are trying to plug this into? Is is USB 2.0? I'm on windows 7 64bit if that helps. Hope you get this fixed, it's annoying as hell.
Forgot to mention, this is on Windows 7 x64 as well.
Im using the ports on my mobo, and its a rather new mobo (XFX 780i). Tried every single port =\

[Q] cant connect to computer

my Evo wont connect to CPU any more ive tried reading all the other threads but still not working
I just want to flesh out some of the details here.
Is the phone charging when you plug it into the computer?
Is there any activity from your PC or the phone when you select "Disk Drive" from the USB menu? (Like maybe a USB error/not connected sound in Windows).
Are you able to access or see it through ADB using the SDK?
Does it work on any other computers?
Have you done anything recently? Did it just happen today?
usb connection not working
I'm having the same problem--my original usb cable was damaged, and I just bought a new (generic) one. Does the EVO require a special type of cable rather than just a standard micro usb?
Here's the details:
USB Debugging is enabled.
Phone is set to ask for connection type (default is disk drive).
Phone charges when plugged into the PC but the computer doesn't recognize it.
In the notification bar, there is the usb debugging icon, but not the other one that usually says charge only/disk drive, etc.
ADB doesn't see the phone.
So far I haven't been able to get to another computer to see if it does the same thing. I tried disabling usb debugging, no effect.
update
Ok, yesterday I got my phone replaced because the screen was damaged. I also got a new usb cable; this one specifically for the EVO. Same thing. I plug it into the computer, and it charges, but the PC doesn't recognize it, and the phone just seems to think it's plugged into an AC adapter. The phone is set to ask what to do whenever I connect it to a PC. Since this is a brand new phone and cable, I would think this would have to be a computer issue, but the PC doesn't seem to recognize that anything has even been connected.
Update: solved--it was the usb port. For some reason the usb ports on my pc case stopped working; plugged into one of the back panel ports and it works fine.
Any microsd cable will work, I'm using my palm pre's now, my htc cable went out a month ago.
I
Chevk device manager whole you are plugging your phone in. just in case there is some bad driver issue, it should show there.
Swyped from a galaxy far far away......

usb host problems

Hello, I have really odd problems with connecting devices to my sgs2. When I connect the cable my phone recognizes it and sometimes recognises also wireless mouse when I connect it. Problems starts when I want to connect pendrive or hard drive (with addictional power cable). The phone doesn't recognise it (already found that i need program to mount from market (doesn't work)) and hard drive shuts itself down after few moments.
Also when I take out cable from micro usb port my phone immidiatelly reboots sometimes it even does it when I just connect and disconnect cable without mouse etc on the second end. I am using rooted 4.0.3 XXLPW. Does anyone has similar problems or just my phone has something wrong with usb port? Looking forward for any helpful responses and sorry for my eng. Thanks.

S20 Plus connection stability with USB 3.0 specifically

Ok this is driving me nuts so I gotta ask...I have a S20 Plus 5G (Verizon) and have a brand new custom-built computer with a ridiculous amount of USB 3.0, 3.1 ports. I have to tether my phone to my PC for internet so I use the USB-C to USB-C cable that came with the phone to connect to the single USB-C port on the computer. I also use said connection for Samsung DEX (not simultaneously, would if I could lol).
With this specific setup, I don't have any issues at all, but I know for a fact that it's not a 3.0 connection because of the cable (the "Device can perform faster when connected to USB 3.0" message confirms as much). The cable is obviously the limiting factor holding it back from 3.0 so I tried replacing it in the setup with various (both USB-C to USB-C and USB-C to USB-A) 3.0 cables and sure enough, I get the correct "connected through USB 3.0" message under my device's name in the devices menu.
However, no matter which 3.0 cable I try or which 3.0+ port I plug it into, I always run into the issue of the device randomly disconnecting/reconnecting every so often. I get the whole disconnected/reconnected sound deal and the "select what happens with this device" Autoplay message. I've tried turning off Autoplay, turning off the USB notification message option, going into device manager/registry and ensuring that every single thing related to the USB ports has the power conservation option turned of, etc.
One major thing is that when I created a USB 3.0 "certified" connection with my mom's slightly older custom-build computer, it seemingly had no problems holding the connection, so it appears as though it's something on my computer specifically that's causing it. I just frankly have no idea what that thing could be at this point. Any ideas?

I have not understood your intention.
Why do you have to connect the phone via USB cable to your computer?
If you have internet via mobile data on your phone and want to share it with the computer, you can tether via mobile hotspot of your phone. Just connect the computer via wifi to your phone's hotspot.
And your device should be able to use Dex wirelessly. I read about it in one of the latest Android 11 OneUI 3.1 changelog.
