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!?!?

[Q] USB connection to PC not working after root

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.

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?

[HELP ME] XT1686 Turbo Charging, USB OTG & USB to PC issues

Hello!
Up until the latest update of April security patch, everything worked well on my phone. But yesterday I noticed that my device did not detect USB OTG (the same USB worked flawlessly on my Redmi 3S Plus). The SanDisk notification just doesn't show up at all. The laptop shows that the USB device is not recognised on connecting phone to it. Also, I do not get the USB configuration notification in the notification bar anymore that lets us choose between charging, MTP and other modes. I've turned USB debugging on & off several times, restarted my device, but nothing helped. But the device is recognised as an USB on the laptop. Also on connecting the device to my laptop, it simply charges. On connecting it to the charger, it does not show "Turbo power connected" anymore. It simply says, "charging". Is anybody facing the same issue? Can please anyone help me if you know a possible solution for this problem?

All of it looks like symptoms of broken data pins in your phone's usb port. Try booting it in bootloader mode and connecting to your pc, if fastboot doesn't recognize it when doing "fastboot devices" in cmd then it's certainly a hardware issue.

I don't know how but magically, last night when I connected the charger to my phone, it started Turbo charging! I checked the USB OTG connection in the morning and it worked! I'll now check the connection to my laptop and report back! Thanks a lot for replying!

Glad to hear it's working. Hope it was just a glitch and doesn't happen again

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?

1. Enable USB Debugging in developer options
2. Download and install ASUS USB Driver from asus website like below. Search for ASUS_Android_USB_drivers_for_Windows

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.
