Can't Connect to Windows 7 After 3.1 Update

I'm using the Google I/O Limited Edition Samsung Galaxy 10.1" tablet. Connected and developed with the device fine on my Windows 7 machine until the 3.1 update last night.
Now, when plugging in the USB, the new USB debugging icon (the Android bee) shows up in the tablet's tray. However, Windows 7 doesn't find the device. I've tried power cycling my PC and the tablet. I've tried disabling USB debugging several times. I've installed Kies, but it does not successfully install the required drivers. I attempted to install the driver listed on Samsung's page for the device, but it didn't appear to do anything.
I was actively developing an app for tablets, and this has ground my progress to a halt. Anyone else experiencing this? Have a fix?

Have you tried a different USB port (on hub) or a direct USB port on the motherboard?

Yeah, that doesn't do anything.

Well mine wasnt working all i did was take the usb out uncheck usb debuggin and plugged it back in and it worked..

Yeah, I've tried enabling/disabling USB debugging, plugging and unplugging the USB. Still nothing.
Again, the behavior I'm getting is that the tablet is indicating that USB debugging is on when I plug the device in. I get the USB debugging icon in the tablet's system tray. But Windows 7 just isn't seeing it. This sure seems to be a driver issue.

Finally got it working. It took doing a factory reset on the device.

I had to turn off usb debugging, then plug usb back in.... tablet said that I had to disable bluetooth, disabled and it worked pefectly! So could it possibly be a problem with bluetooth!?!?

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.

USB Type-c port : bugged or broken ?

Hello guys, here is the bug I experience
First of all i'm sure the cable isnt guilty as I tried two different cables, with one of them being new, getting the same result/bug
Whenever I plug something to my usb type-c port, it can ONLY and ONLY charge !
When i plug the phone to a PC, it won't recognize a phone is plugged ! It charges, but I don't have the window where u can choose between MTP, Charging,...
Of course I have enabled : USB Debugging, and switched from "Charge" to "MTP" in dev options
Even the USB otg doesn't work (with "OTG stockage" enabled ofc)
From times to times I could connect the pc to the OP5, but by plugging / unplugging the cable like 20 times... And now it's worse as it doesnt work at all !
It used to work perfectly in the past , is it possible the system can bug to the point this bug appears ? Is the type-c port broken ?

I have the same problem, the USB port can only do slow charging. It doesn't connect to PC/Mac and doesn't dash charge either. Taking it to service center as i'm pretty sure it's a hardware issue with the USB port.

Try downloading OnePlus USB drivers on pc you connected device to. https://www.androidfilehost.com/?fid=673368273298966498

MTP should work without those.

No it's not an issue with the drivers. The phone used to get detected fine and would do dash charge properly earlier, it suddenly stopped working.
I visited the service center, they confirmed my suspicion, it was an issue with the USB port module. A hardware issue where some of the pins on the USB module stopped working for reason, and as a result phone wouldn't receive connection from the cable. They replaced the module for me and the phone works properly again.

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.

Windows 10 HP laptop doesn't recognise the phone.

Guys I'm trying to connect my phone to laptop but phone doens't get recognised in the laptop. The device makes sound and so does the laptop. No pop-ups in either of devices. The phone starts to charge but no option in the notification shade to change the mode of connection though. I've tried with turning on the usb debugging too, but no help.
Laptop pups up an error message later that the "LAST USB DEVICE YOU CONNECTED MALFUNCTIONED. WINDOWS DOES NOT RECOGNISE IT".
Is this falut of my charging port or of laptop? Or windows 10?
I've tried connecting to all other ports and with different cables. My all other android devices connect though. Please help.

I've had this issue with pen drives and my USB port had an issue(short circuited).
Check these :
Try running devices troubleshooter from control panel.
If the phone is charging properly by using the same cable , it's probably an issue with the laptop.
Is it on pie?

Sir I've tried debugging thing already and set the option to MTP. I've run troubleshooter too but windows couldn't identify and solve the problem. I'm guessing the problem is with windows 10. So I've decided to installed windows 7 in a different drive. Maybe that'll solve the problem.
Phone is running on Oreo.
Note:- I think micro usb has four pins. One among them might be a ground pin. One must be for charging and other must be to transfer data. Correct me if I'm wrong.

I had several times repairing phone with broken micro usb connector, it has 5 pin to be soldering on it. 2 for the power and 3 for data transfer. If the cable is fine for other devices then maybe the problem is not from the cable itself. I had an experience like that case before that if the notification from the pc says connected device is malfunctioned, that may caused by when u first time connected the phone to the pc, the device is disconnected when it still trying to instal the driver. When u connected the phone to pc check on the device manager, if u see "!" icon there, then theres the problem, ur phone driver not installed properly, u can try manual instal of device driver from there.

Last usb device you connected malfunctioned. Windows does not recognise it
"USB device not recognized. The last USB device you connected to this computer malfunctioned, and Windows does not recognize it” always appears in Windows 10 and Windows 8.
And the reasons for the issue contains:
The currently loaded USB driver has become corrupted or unstable
USB drivers need to be updated
USB drive may be entering selective suspend
USB has some damaged files or bad sectors
USB drive has not been formatted correctly
For different reasons, you need to take different measure, but you can directly format it via AOMEI Partition Assistant to solve the usb device not recognize issue.

The USB port itself was damaged. So I got replacement and now the new phone works fine with same laptop. Thanks you all for your replies.
