Can't get Nexus 7 to show up on computer

Shows up on my laptop but not on my desktop, have tried back and front USB ports
have uninstalled USB drivers, reinstalled USB drivers (universal adbdriversetup6 downloaded from xda sources)
downloaded android SDK manager and installed whatever USB stuff it had there
used USBdeview to remove any nexus 7 related things and then re-install USB drivers
Cannot for the life of me figure out what's going on... can anyone help me please
When I plug it in my desktop it makes the sound like something got connected... even has the safely remove hardware thing with nexus 7 there, but nothing in my computer
also have tried with/without USB debugging
tried removing my rom and flashing stock etc
Nothing has worked so far

and yes forgot to put in the title but this is for the Nexus 7FHD 2013

Is there a chance you are using usb3.0 port and can switch to usb2.0?
I would suggest you backup, flash stock, and redo your driver deinstall/install on stock. Try to get it working there first. Make sure USB debugging is disable on stock.

tried USB 3.0 as well as 2.0 on desktop doesnt work, shows up as a device on safely remove hardware, and I can also see it under other devices in hardware manager or whatever but doesnt display in computer
USB debugging enabled or disabled on stock doesn't work.. tried going back to stock and doing driver installation etc as well

In device manager are there any unknown devices?

Did you remember to

Driver instal with WinXP
I went around with this problem after both my Win7 laptop and WinXP desktop both recognized my N7 2013 the first time I connected to them. I had no problem dragging and dropping files.
I had then returned the tab back to BB for a exchange for another. This time after setting up the tab and setting the MTP file toggle and USB settings correctly......The Win7 laptop worked find and recognized the N7 just like it did on the first tab. But now the WinXP desktop did not work and only saw the N7 as a ABD device.
You may already have the correct drivers (if not those are available here in several posts). You just have to direct windows driver update to the correct place for the MTP driver. Here is how i did it.
1. Open up the Device Manager on your PC and locate the Android device it sees. Select the update driver option and you get to the "Welcome to the Hardware Update Wizard" screen.
2. In this window it asks "Can Windows connect to Windows Update to search for software?" Select the 3rd option ' No, not at this time"
3. In the next window "This wizard helps you install software for...." Select the 2nd option "Install from a list or specific location (Advanced)
4. In the "Please choose your search and installation options" window... go down to the bottom and select "Don't search, I will choose the driver to install" option.
5. Now finally the window we need..... "Select the device driver you want to install for this hardware" The "show compatible hardware" button should be selected...if not check that box. You should see 2 choices in the "Model" area..... Google Nexus ADB Interface" and what we need to select " MTP Device" click on the MTP Device and hit next......it should install and your Nexus 7 should then show up properly.
Hope this works for all that have had a hard time as I did....I just found it odd after getting a replacement N7 my XP desktop did not recognize it as it did to the original one I used the day prior.

Just go in settings then storage and then computer usb connection by opening preferences in storage and then make sure mtp is checked.

If nothing else here has helped you solve this issue, check my thread, it should be of some help to you...

I'm having an issue where I can connect to my laptop in debug mode, but I'm not able to connect in the MTP mode with debug turned off. I expected to be able to mount the device storage in either mode.
Is that correct? If so, any ideas? I do notice I can't seem to get the MTP driver to stay in device manager.

Device Shown as Offline after GPe rom flash

Hi all,
I rooted my M8 recently with the Windroid toolkit. Everything worked great, and I flashed the digitalhigh GPE rom and love it.
Now when I try to connect my phone to my computer, I do not receive the prompt for RSA key trust. My phone shows offline on my 8.1 VM and it is just not found on my Windows 7 machine. It also shows offline on a Macbook Air. I have tried everything I can find to get USB debugging to start working again but I just can't seem to find out what needs to be done. I have the latest version of the HTC drivers I believe and I should have the latest add drivers. On Sense, I had to turn on USB debugging and select the phone to be mounted as a disk drive for WinDroid to be able to root my phone.
So, how can I get this fixed? Is it an issue with the ROM? Is there some way that I can turn on a disk drive mode on the rom.
Any help is appreciated!
Thank you.

Check the device manager in Windows. Does it state a 'unknown device' (or similar)

Looking at device manager, it shows my phone in two different places. It shows once in 'other devices' as just android phone and then under 'portable devices' as the name of the phone.
When I go into detail under 'other devices', device manager show that drivers are not installed but says everything is installed correctly under 'portable devices'.
I have the latest version of Sync Manager, so by that reasoning I should have the latest version of the HTC drivers. What else would I need to get my phone to not show as offline?
Thank you

Uninstall Sync Manager. It doesn't play nice with ADB. The only thing it is good for if you are rooted is installing the drivers. After that, get rid of it.

Still having issues
Hello all,
I am still having issues with getting my computer to recognize that USB debugging is on and getting it connected to my computer with adb. I have uninstalled sync manager, and yet my phone is still not recognized.
Under debugging in developer options, the only thing I have checked is USB debugging.
Is there something else that needs to be checked in the developer options? Why do I still have this issue?
P.S. I would post pictures, but I can't unfortunately :\

Thanks for the reply bford152. Oddly, I do not have this option available to me.
I would like to post pictures of the options I have under USB debug. But even posting a link and not having it parse still tries to read it and says I cannot post outside links. Next question, how do I attach photos without adding it as a link to the post. Maybe I'm blind, because I cannot see an option to do this.
Thanks everyone!

What's your adb version ?
It needs 1.0.31 for Android 5.1 and 1.0.32 for Android 6.0 (minimum requirement)
Have you tried with a secured kernel/boot.img ? If you don't have "Revoke USB debugging authorizations" in Developer options - means that you have insecure kernel installed.

I have adb version 1.0.32, so all good there.
I don't seem to have "Revoke USB debugging authorizations". So, I have Elite kernel right now and I guess that's the issue. I will get a different kernel and see if that helps.
Thanks!

Change the option to File Transfer from the popup/notification on your phone when you connect it to the PC. It works for me.
EDIT: If it still doesn't change, check the adb drivers.

i am not getting any popup.

Check the sliding switch on the right hand edge of the op3 is "down" to allow ALL notifications. There are plenty of "install OP3 drivers" videos on Youtube. Windows drivers are also on the phone.
This should still work - the drivers are also supplied on the phone. Doing nothing other than connecting a op3 to a windows pc should cause a cd drive to appear in Windows Device Manager and in File Explorer (look under "This PC") for "CD Drive (drive letter: OnePlus Drivers" . Double Click the icon and run "OnePlus_USB_Drivers_Setup.exe". If you are running a recent version (and clean installed in the last few months) of W10 Pro then you may hit driver signing issues

USB error PLEASE HELP!

As regards the attaching of files, you have to have a minimum number of posts to be able to do that.
As regards the USB, be a little more specific like what you are trying to do, which ROM you are running, whether you are rooted, what happens when you connect the phone to PC etc which will enable the members to help you.

There could be several reasons for this, but lets start with the basics.
Have you tried a different cable?
Have you selected File Transfer (MTP) from usb options?

I get a windows sound like its connecting then in the bottom right where the time is next to that is a root sign then I get a pop up saying exactly.....The last USB device you connected to this computer malfunctioned and Windows does not recognize it. Recommendation.. Try reconnecting the device. If Windows still does not recognize it, your device may not be working properly. When I go to the Device Manager/Control Panel it doesnt do anything. I've tried to add adb to the path but maybe added it to wrong path now it won't come on. If there is a work around maybe to re-add to right path. Device Manager was fine before I added adb and added path as per internet search. Device Manager before would say something like error 39. I've tried MTP that doesn't get it to open up either.

I cant even root for the life of me now, Im on 8.0, I'm trying to just root the phone and to start the computer has to recognize it I understand but it won't, with my Oneplus 2 was fine,(I'm thinking maybe phone doesnt have the drivers built in to the file system, you know when you plug in and turn on MTP it shows the drivers app for Windows?) the only thing it errors plugging in.

On my son's pc running windows 10, I didn't have any issues connecting my OP3 to it and viewing files, nor did I have to install any drivers, same for Windows 7.
Hook phone to pc via usb cable.
Pull down notification bar and select "File Transfer" from usb options or go to Settings and search USB and select USB Preferences > File Transfer.
Browse phone from Window's file manager.
If still having issues, you can try and install Oneplus USB drivers, reboot pc and see if the phone can be recognized.

For some reason it's working now don't know what the problem was or even if it was something I did. Either way it's fixed.

If you are running Win 10, you will have to disable driver signing before the correct drivers are installed. May be that was your issue.

Problems with USB connection

Hello! I have a mi A2 lite, I can't connect it to the computer using USB, it doesn't install drivers, it doesn't appear on installed devices. I've tried all the tutorials available on YouTube, but it doesn't work, does anyone know what I could do to fix this?
- I already downloaded the drivers and installed manually, but nothing changes.
- I've tried on multiple computers and none work
- When I bought the cell phone it connected, but after a while no more.
Does anyone know any solution to this problem?
Thanks!

Did you allow the phone to talk to USB. You must use the notification to enable file transfer or set the default in settings or enable debugging if you want it to show up to USB.

It does not appear the notification, but I have already tried to activate by the settings too, I already connected the debugging mode, but it also did not work. When connector it only loads, there is no other action.

I have the same prblm ...... any solutions? Help me please

Same here on v11.0.12. Its a driver issue. You need to install latest xiaomi drivers + qualcomm drivers. I fixed it before but it doesnt work again after i uninstall drivers.

I connected phone to PC with only old original short cable, no other cables worked :/

Have you tried to clean phone's USB socked? There are some spray contact cleaners, that can be used for this purpose.
