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.

I would like to get my nexus 7 to connect to the internet via a cdma usb modem. Using my lg rumor touch and sprint with a data package a usb cable and a otg cable. However when I plug my phone into the nexus 7 the phone doesn't give me the option of what kind of connection it should be. When connected to a computer I get the option. Is there some diver I need on the tablet or could it be an issue due to me using a 3rd party cable to connect the phone.
Hi,
I've got a rooted stock 4.2.1 N10 here, the USB connection to any PC is no longer working. When I plug it in the charging icon on the tablet appears but nothing else happens.
Tried different cables, different ports, different computers. Have disabled/enabled debugging options and storage type of the tablet PTM/MTP.
I'm hopeful the port on the tablet is still working as OTG cable and pen drives work fine.
Any help or suggestions our there for me?
Cheers
I have similar problem. I cannot enter to nexus from windows after rooting.
Install the right drivers.
Or it could be in a couple incredibly rare circumstances that are not at all likely, that your USB cable is broken and the data pins are able to connect. But you probably have a driver problem.
Hi guys, I have this really weird issue occurring. I have my note 3 connected to my computer via usb, but it does not stay connected. My computer keeps making a noise of new device connected, then disconnected. The phone connects, few secs later, disconnects. I have tried 3 different usb, 1 is the original,, different usb ports. It cant be the cable tho, cause it charges fine, and i wiggled it while charging. I let the drivers install when i first plugged the n3 in, so those should be good.
Any idea? could it be a ROM issue? Really need it to work, since I use tethering (

What rom are you using? And have you tried reinstalling drivers from samsung? http://www.theandroidsoul.com/galaxy-note-3-drivers-installation-guide/ and have you tried just using the micro USB cable (not the USB 3.0)
biggins 4.5, yea i tried those drivers, didnt try usb2.0 yet.
Its literally sitting here connecting, then disconnecting on and on, i have no idea, not even moving it

It could be the data pins in the cable/phone, the power pins would still let it charge even though there's still supposed to be energy going through the data pins when charging. And have you selected a different option when plugging it into the computer (from installer, media device, to camera) from the options that note 3 provides? (click the icon in the status bar when you plug it in)
yea i tried camera, its on installer by default i think and i tried mtp also, usb3.0 said it required airplane mod so i didnt try that. How could i check the pins>

Well it you look at the port and they're not bent or snapped then it isn't the pins. What about USB 2.0?
Will try 2.0 tomorrow, here is a pic of the pins, if you zoom in do they look ok?

What OS is your computer running? There are some USB issues with windows 8.1. I was having the same problem at times but there was a fix in optional updates that have seemed to clear things up for now. I think it's the download numbered...2914219. I'm not completely sure as I did a few weeks ago.
Just for the record, I have had trouble with certain cables in the past. Sometimes computer didn't like a long cable.
Pins are absolutely fine, only reason I even mentioned those was because one time a little kid plugged my streak 7 cord in upside down and jacked the female port to crap. And as TheAfroSamurai mentioned it might be your computer, I had trouble with a long cable with my kin 2. Different cable fixed it for me.

I can connect my V20 to a Windows PC via USB cable, and transfer files back and forth. I had to pick something on a menu the first time I plugged in the phone.
However, if I plug a USB stick directly into the V20, it does not recognize it, or respond at all. My friend plugs the same USB stick into his V10 and an app pops up and shows the folders.
I'm using a micro-USB to USB-C adapter on the stick to plug into the V20. I know the adapter works, because I tested it when connecting to the PC.
I have searched settings for "USB" and it only comes up with USB tethering.
This is an AT&T stock phone, using the stock launcher. No root or anything.
Any idea how to get the USB recognized on the V20? Thanks.
it might be that the USB host function doesn't work with those adapters. have you tried plugging in a USBC to USB adapter and plugging a flash drive into that?
something like this

I've tried the same thing without success. My note 3 & 4 worked fine. I also had a Note 7 and Nexus 6P and it didn't work with those either.
has there been any advancement on this issue?
Did anyone find the answer to this? My V20 used to boot up a USB stick but just stopped working one day.
