Having some issues with USB recognition

I'm trying to get the one click lag fix 2.0 onto my phone. However I've run into quite a few problems. Everything was fine, I was having no problems with connecting to my computer. However when I connected the USB cable again, the phone receives power from the cable but neither the phone or laptop recognize each other. I tried doing all sorts of things (turning on USB debugging and all that) but to no avail. I decided to try to do the factory reset. While the phone was rebooting the "Found new hardware" bubble popped up and it recognized it but as soon as everything was loaded it was gone.
Then I tried restarting it with USB debugging off and it DID recognize it. However once I restart it like that there is no way to turn USB debugging back on without disconnecting it... and once i do that and activate USB debugging, the phone is not recognized again.
This has been a pretty frustrating ordeal and I have tried it on multiple PCs. I am using the stock cable that came with the phone...
Any ideas?

Same thing happens to me. Stock cable would show up as a device when plugged into multiple computers. I swapped phones but I'm sure its just a cable issue.

Have you downloaded the latest USB driver for the phone from samsung's website?
What OS are you using?
Make sure you plugged your USB cable into USB 2.0.
Also, make sure the USB sliding door is fully opened and locked. The door on the phone could prevent a good connection from taking place.

Yes, I do have the latest driver.
I have tried doing this on both Mac (snow leopard) and windows XP (different laptops).
All the connections are good and they are all certainly usb 2.0.

Windows won't recognize my SGS2

Hi,
I have for two days tried getting my PC to recognize my SGS2. With no luck. I want to ROOT my phone.
I am using Windows 7 64-bit and gingerbread v2.3.5
- USB-debugging is turned OFF.
- I have tried to format the SD-card, even used different SD-cards.
- I have tried using another PC, with no luck.
- Tried diffrent versions of Kies; 1.5, 2.0, and 2.1
- Tried diffrent versions of the Samsung Mobile driver; 1.3 and 1.4.8
- Tried using a different USB-cable (the one I'm using, is original and i can see that my phone is charging.)
- I have formatted the phone several times.
- I have tried typing *#7284# and changes the USB setting from Modem -> PDA
- Windows Drivers are up-to-date.
- I cannot see anything in the Device manager.
What else is there to do? Is something wrong with my phone?
Is there any APK, besides from Gingerbreak, that i can use to root my phone?
Cheers

Could you tried it in another PC with Windows XP?

When you plug it in to the USB port... Does the phone start to charge up?

Sounds like a hardware issue, i too have Windows 7 X64 on my laptop and no such problems.

Give a shot with USB debugging to ON.

I had the same problem.
This may sound stupid, but it does work, try another USB port.
I just plugged my USB cable into either one of the front USB ports on my PC (WinXP) and sometimes the phone connected (Debugging ON: phone was an external hard drive. Debugging OFF: phone connected to KIES) and other times it didn't. I tried toggling the Debugging, switching off and on the phone, changing USB cables, uninstalling KIES and then reinstalling KIES.
I finally noticed that the phone worked fine on the front left USB port and not on the front right. I have the same thing happening on my work's PC (only it was the front right port that worked). The rear USB ports didn't work.
I doubt that it is a problem with the PC operating system (I found out later that someone with a Mac had the same problem). It therefore must be with the phone's software recognising a connection with a computer and only wanting to connect through that initial connection port.

ive noticed this problem too of it only working with certain usb ports and not others on the same pc. Quite annoying when i was trying to use my phone to transfer some files from another computer and the phone wasnt picked up by the computer.
I think it may have something to do with using MTP rather than standard USB mass storage.

Never plug your phone or any other usb powered device into your front USB ports. most of them do not supply full power. As a matter of practice you should always plug your phone into a direct motherboard USB port on the back of your computer.
I had the same problem with my front ports several times on several computers. My first galaxy S1 would not work on my front port either. all problems were solved by plugging into the direct motherboard usb ports.

Why would you turn USB debugging off?

Do you have Administrator rights?

try installing drivers manually on your pc
and then plug the phone ( usb debugging off )

Try 32bit system
Try using a 32bit XP or 7 PC someone I know had the same problem their Win 7 never gave the problem when flashing or connection with their SGS2 for over 6 months. And just the other day they had a problem so they used a XP 32 bit PC connect ok flashed ok once the phone was rebooted they connect to their Win 7 64bit and the PC saw their handset. So what gives

I have plugged in many different phones and other devices that take their power from the Front USB ports on my PC. Power has never been a problem. Recognising a device can sometimes be a problem (but the same problem happens with the rear USB ports).
I regularly charge my SGSII via the Front USB port of my PC (both work and home). Quite a few of my workmates now do the same because a spare microUSB cable is much cheaper than a good mains charger and also they can back up their phone and transfer files as well.

This worked for me
1. Unplug the USB cable
2. On the cell phone, dial the following number: *#7284# Once the last # is hit, the PhoneUtil application is launched. Choose USB -> Modem and then USB -> PDA mode. The good mode should be PDA. Even if the mode is PDA, switch to Modem and then back to PDA.
3. Plug the USB cable.

Sometimes if you're not using the cord that came with the phone it won't recognize the phone
I had the same problem with my phone but I found the cord the phone came with and it solved the problem

Try turning off your antivirus first for drivers to install. Worked for me.

I have just installed SiyahKernel 2.3 and Windows 7 Ultimate 64 bits did not recognize my SGS2.
What I did is turn on and then turn off the "USB debug" option. It was off at the beginning but... I did that just in case and...
That solved my problem.

Similar issue
My phone charges when plugged in but won't mount. It worked fine until about a month ago.

I'd similar problem.
My SGS2 couldn't be connected to PC (Windows 7 Ultimate 64bit) by USB cable, but it could be connected via Wi-Fi. I found out, that my, however original, USB cable was faulty (could only supply a juice from USB port ). When I used my wife's cable (she's got SGS2 too), everything was fine: my phone connected to PC, Kies v.2.1.0.11112_41 checked firmware and wanted to update, but couldn't do it, because battery was almost flat - I'm charging it now.
Will see tomorrow, however I was able to connect SGS2 to PC via USB cable

Still having the recognition problem, however you can get around it a number if ways. Use Kies wifi to get files to your phone. Use mobile Odin to flash.
Highly recommend to pay the $2 for pro version, that way it will stay rooted.

USB3 not working

Hello, I have both a new Galaxy S5 and a recently installed Windows 7 64bit PC.
I just bought an USB3 cable and tried it: when I plug the cable in an USB2 port, all works as expected (Windows warns the device can go faster if connected to an USB3 port); when I plug the cable to an USB3 port, the phone says connected to USB, message disappears, appears again and then definitely goes away (just charging); Windows says the device is not recognized.
I asked where I bought the cable and they changed it with a new one, but the effect is the same.
I tried installing latest Samsung USB drivers (1.5.51.0) without succcess.
The phone is not rooted.
Can you please assist in solving the problem?
Thank you!

USB 3.0 drivers installed for the motherboard?

How can I check? Windows says the device can go faster with USB3, maybe this means they are installed?

Go to your motherboard manufacturers website, drivers section, and look for USB3.0 drivers
For mine they are called ASMedia_USB3
Windows saying they can go faster with USB 3.0 just means windows has detected a USB3.0 device

Ok, I went to Lenovo Thinkpad download section and installed Interl USB3 drivers; I'm going to reboot

If that doesn't work, check your BIOS for USB3.0 settings, see if there is anything in there you can tweak

No luck...
I'm not sure it is on the PC side: I tried an USB3 mass storage device and it goes faster...

Maybe the cable is faulty then, or not up to USB3.0 standards
Is it a genuine S5 USB3.0 cable, or something from ebay or somewhere?

It is from "somewhere", but this is the second one with the same problem, chances are lower...

Second one from the same place?
Worth trying a genuine cable, the most likely culprit is a cheap cable from 'somewhere' rather than a PC or an S5

I'll try as soon as I find one!
What I wanted to check was if there's anything to "enable" on the phone or Windows.

Not that I know of, although I've not used a USB3.0 cable on my S5 yet - I haven't seen anything in the phone settings, and I know that my PC USB3.0 works fine without doing anything other than installing the drivers

@pdario
Please check you marked in phone 3.0 mod.
(when you plug to 3.0 usb port, you have option in phone to choose USB 3.0 mod)
Work?

The phone does not say it is connected to USB, it only shows it's charging.

So that the problem.
Unistall all android devices drivers you have, then plug the galaxy s5

How can I uninstall all the drivers? Where do I find them?

Nexus player not showing up in Device Manager

I'm trying to unlock boot loader and root my device, But for some reason when I plug my nexus player into my computer no drivers get installed and under device manager there is no android device or anything of that nature under any of the categories. I've made sure developer debugging and USB debugging are enabled and turned on, but nothing seems to work. I even installed google usb drivers if that has anything to do with it. So does anyone know why its not showing up?

Most likely it's the USB cable or OTG cable, one of the two could be faulty. Another thing, try different USB ports on your PC. Try turning the USB debugging on and off several times, USB cable and OTG cable must be attached to your PC, while doing this. Remember now, your PC must also be authorized for the connection. You should see a white pop up, just check mark the block, click on OK.

Yes try different USB ports and different USB cables. My PC didn't recognize the NP when using the front USB ports, but it works fine when using the back ports.

It shows up if I turn debugging on and off a lot but when restarting while rooting it wont show up again and I think this is the reason my rooting isnt working right could that be a problem?

USB connection not detected by Windows 10

Can anyone suggest how to make windows 10 recognize the phone when connected via USB cable?
Latest official android version and USB debugging enabled.

Which cable are you using for connection to the computer? the cable that comes with the phone is for charging only, you'll need a data cable for connection.
Some users have reported issues when flashing or sideloading using a USB 2.0 cable. The cable included with PH-1 is USB 2.0 and is primarily intended for charging. If you're flashing or sideloading PH-1, we recommend using a high-quality, spec-compliant USB 3.0 (or higher) cable.

ive used both 2.0 and 3.0, but never the 3.1 USB C style. never had an issue, but some of the cables look premium and are cheap crap that connect and disconnect on a whim because the pins arent contacting unless the cable is perfectly straight

I'm using this cable: https://www.amazon.com/gp/product/B01N5KL10L/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
It is supposed to be a data cable and looks pretty decent.
Are any special drivers required ? ( I have installed the USB driver found on the Essential support page but no dice)

I have those same cables, they are a bit touchy when it comes to staying connected especially in a USB 2.0 port. Make sure you're using a 3.0 port and once it connects, don't move it much. Not a great solution I know but what can you do.

I tend to leave Device Manager open when I install new hardware. It often helps understand the sequence of things. Do you hear the Windows Device Connected Sound? If nothing is showing up there, it's the USB cable

Well.. I got my phone last Wednesday and I just got the issue when I got USB3.0 to USB C cable last Friday. (my main PCs do not have USB-C port)
The symptom is;
connecting USB cable and change connection mode to "file transfer" or MTP, it looked going to connect, but actually failed or disconnected when I tried browse the device or copy files.
After few research, I could resolve the issue.
Here are the what I did.
First, I have to download and install USB driver from Essential home page. (check "Essential Developers" page. I cannot add link here yet because I'm newbie here.)
Second, Now I got connection, but still the connection was unstable especially when I copied big files (about 200~300MB or more). The issue could be resolved after turning on "Disable USB audio routing" option in "Developer Options". (You should enable the "Developer Options" first)
Third, Now I have no problem on Windows PC connection, but I got a problem with Ubuntu 16.04. And I have found the it happens only when I connect it via USB hub. After connecting to PC directly, the issue has gone.
I have no problem on USB connection with my PCs now.
