Windows 7 - Installing ADB

Ok, I've just upgraded to windows 7. I was pretty psyched about the whole thing, and my computer seems like a whole new machine, coming from XP 32 bit.
So one thing I'm attempting to get adb to work with my phone. Heres my first problem - right off the bat, my computer doesnt recognize my phone as anything but an unknown device. YES I'VE TRIED DEBUGGING, DISK DRIVE, ETC., but nothing works.
I go to device manager, all I see is unknown device. Ok fine. I download the adb files that allow you to download the Android 2.1 thing and usb drivers. Still nothing works. I go to device manager, try to update the drivers for said "unkown device" and i get a message "the drivers are the newest up to date" or something. I try downloading the 64-bit HTC Hero drivers, same thing. I download and install HTC Sync, same thing.
I get this message when I plug the phone in...
"USB Device not recognized
One of the usb devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message"
So my question is, how do i get my computer to recognize my phone, even as storage device??

try uninstalling htc sync and using a different usb port. does that work?

And to address how to get it to recognize as a drive, when you plug it in you should be presented with options where you can make it a disk drive. Or pull down your notification bar and change the type.

On the phone yes, I can select a different type. On my computer, I just get that unknown device message.
And out of the blue I just tried a different USB port, and now it works as a storage device.

Did you restart the computer after installing the drivers? Sometimes mine gets a little goofy like that.

i had that issue with one of my usb ports too. i think sometimes a bank of usb ports are used as basically a usb hub, and the evo doesn't like that, from what i understand.

Reboot comp, reboot EVO. Connect 'em, and then go into Device Manager, uninstall the "unknown device" (EVO), and then have it scan for new devices. Now, when it says scanning for drivers (or something to that effect) look for an advanced or "skip checking Windows Update for drivers" option. Then navigate to the ADB drivers in the Android SDK and tell it to use those. Make sure you have USB Debugging turned on, and EVO's set for "Charging Only".
If that still doesn't work, then there's an incompatibility with your computer's USB controller and Win7.

If your computer is old enough, incompatibility is a possibility. See if there's other ports you can use, like on a different side of the case. Also, what brand computer?

stop! lol its fine. it works. i guess i should have stated that i've been on these forums for quite a while, and have flashed and rooted a few different phones using this computer, but with xp.
i just switched to windows 7, and of course lost all my drivers, and everything I had saved would have to be switched to 64-bit. I just couldnt get anything to work, but it seems to work now.
and I dont know what brand necessarily this computer is. i built it. I do have a dell keyboard though.

[Q] Drive Mode Windows 7

Hello,
I just got my Evo. Love it.
My question is, I enter drive mode on Windows Vista, but when I try to enter drive mode on Windows 7, the drive does not show up. In the device manager, it shows up as an unknown device. In devices and printers, it shows up as an Android phone. ????
Any help would be great!!!

did you install htc sync on the windows 7?

Mine did the same thing on Windows 7. Actually I'm on my third Evo & all of them were like that. I never got the option to choose in the notification bar & HTC Sync never helped, the phone wasn't recognized.
Make sure you're using the cable that came with the phone or at least one shorter than two-feetish. Long 3rd party cables won't work. Download widgetsoid 2.x from the market, it's a power control widget & it's great. Make a 1x1 switcher widget & only select "usb storage" under the first category. Ignore all of the other options because you'll be removing it after anyway. On the bottom panel, scroll all the way to the right & click apply. Sorry for the lengthy description, I'm not sure how well you know how to work your phone. Okay, turn on USB debugging in settings > applications > development. If you feel the need you can reboot your phone. Be sure to not kill anything.
Connect the cable to the computer. You should get a notice that usb debugging is on, don't touch it. Find the widget you made & touch it. You should connect after a couple seconds. If it tells you to connect your phone first, then it isn't working & this advice was pointless.

The device it's seeing is the adb interface from the phone (Unknown Device). If you enter storage mode (ie Cable plugged in -> Notifications > USB Connected > Turn on USB Storage), it is a different device that should be recognized by Win7 native drivers. If not, you could try installing HTC Sync and then rebooting, then plugging in your phone and try that.
Worst case, get a microSD-SD adapter that will let you put your SD card direct in the PC (not the best solution, but it works).

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.

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?

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.

Thank you guys SO MUCH for the help... I actually just returned my unit to staples because those POS wont give me a price adjustment vs google play

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.

usb data not working after september update

USB cable only charges the phone when connected to computer. Tried the following
1. Using 2 different cables which previously worked for data but phone only shows charging.
2. Using pc and Mac and both does not see phone. Looked in device manager of windows but it nothing shows up. Both computer previously used for data transfer on this phone
3. Looking inside usb-c port but no lint or dirt. Although just before update to September security patch my phone has some water on the screen which I wiped off. And the phone does not show sign of problem other than no data transfer to computer
4. Factory reset phone and same thing
5. No notification shown for changing charging only to file transfer
6. Computer doesn't Bing when connected.
What else can I try? Anyone can help or confirm if their usb-c works after September update so I can narrow down to hard ware problem.
Anyone diagnosed this hardware problem before?

Do you have developer options enabled in settings? If you do go into networking/usb configuration and change that. If you don't you can enable it by going into about phone in settings and tapping the build number 7 times.

I tried changing the options to MTP, PTP, midi, charge only, etc but non of them make any difference to the computer, nothing pops up and does not show as new item connected in device manager

did you try changing from charging to mpt, and maybe back and forth, while the phone was connected to the pc? I have the same update on my 5x and mine is working fine.

Tried changing when USB connected and when not. Doesn't seem to make a difference.

I'm not sure what to tell you. You could try flashing the firmware package prior to the sept update. You'll have to re-set up your phone, but if you've already done a factory reset it won't be worse than that. That could tell you if it's software or hardware

I don't know how I can flash a previous firmware if I don't have USB access.. it's really frustrating. Looking from ifixit. It does not seem there is any chip near usb-c other than voltage control.
Can't seem to find how I can look at logs to know if USB has been engaged or if there is any error message. It's all dead end and my phone seem to be the unique case.

Are you rooted and do you have chainfire's flashfire?

I should have asked if USB was working before the sept update? I had a problem where the PC would recognize the device but couldn't run fastboot. This solved that problem but it sounds different than your issue

USB worked fine, I am using it for Android studio, and transfered music across as well. Looked at the post and it seemed that has to do with device manager. Problem is mine does not show up any changes to device manager. I.e . No ADB or other device. Seemed like no data is exchanged and windows treating it like a battery or something

Any fix for this?
I've hit the same issue and wondering if anybody has a fix for this yet?
I'm using linux and seeing no usb activity at all from my nexus 5x after sep 17 update.
I've tried multiple cables. Cleaned the usb port on the phone. Multiple PCs.
I've connected to the phone using adb over tcpip and seeing nothing in logcat except battery logs when the usb cable is plugged in and out.
Turned usb debugging off and on.
I've set usb mode in developer options to mtp (it was on 'charging') and restarted the phone. Then find the option is forced back to 'charging.'
Logcat entries during boot show no failures in regards to usb connectivity.
Charging works fine but no data connectivity via usb at all.
Anyone got any other ideas?

Hello world.
I had the same issue.
To solve the problem :
- unlock developer mode
- switch on debug usb
regards
J.

I had this problem too- did not have to enable USB debugging though, just enabling the developer options fixed it for me. Which is odd because I definitely had them enabled previously... I guess a recent update reset that and for some reason all the USB data options are tied to developer mode now.

I've got 790 (american, as i know). The same issue, no response from service, guarantee, doesn't help, pc shows it as unknown device. some other bugs, mobile data fails, no sim detected after a few seconds, violet camera with no focus, but nice when the distance ia ok, so matrix works ok, but no stabilisation.
Then, bad battery, it seems that the bank ia ok, but controller works bad. it charges enough time to think that the capacity is not degraded. I suppose that usb controller (pc connection and fsat discharging) are nearby problems.

None of the above posts worked for me on my N5x (8.1.0 March), but searched some more and found this to work for me:
https://productforums.google.com/forum/#!topic/phone-by-google/DfpqXN1UfWY

Hello everyone. I'm just resurrecting this old thread so I can provide the solutions I have found to this problem. It appears this symptom has multiple causes, and there are different solutions depending on the cause. I have seen this problem twice now on my Nexus 5x (stock, no custom ROM) and solved it both times.
1. SOLUTION #1 - Messing with USB Configuration in Android
First time I encountered this problem, I did the following:
- USB Debugging was already enabled
- Enter USB Debugging menu
- Scroll down to "Select USB Configuration"
- Open this and select MTP, even if MTP was already selected. On my 5x, MTP was already selected, but selecting it again fixed whatever was broken, and the phone was immediately visible again in the Windows 10 interface when connected via USB.
2. SOLUTION #2 - ClockworldMod USB Driver was installed. Replace with Google driver
The second time I encountered this issue, the Solution #1 above did not work. Surprisingly, the adb devices command successfully detected the Nexus 5x. It's just that the phone wasn't showing up in the Windows 10 File Explorer interface.
The root cause of this problem was that I had installed the ClockWorldMod USB Driver because I was playing around with their Vysor App (on a different phone.)
BTW, I think the Vysor tool is really nifty for screen mirroring purposes!
To resolve the problem, I replaced the ClockWorldMod driver with the regular Google USB Driver.
(Sorry, XDA is not letting me post links because of my low post count. The link is:
h++ps://developer.android.com/studio/run/oem-usb.html )
The procedure is:
- Download the Google USB Driver from the link above and extract the ZIP.
- Enter the Windows Device manager
- Find 'Android ADB Composite Interface'
- Open the properties of 'Android ADB Composite Interface' and you will see it is from ClockWorldMod.
- Right click on this Interface and Select 'Update Driver'
- Click on 'Browse My Computer for Driver Software'
- Click on 'Let me pick from a list of available drivers on my computer'
- Click on 'Have Disk'
- Browse to the Google USB Driver you downloaded.
- Select that driver and load it on top of the ClockWorldMod driver. (Windows may claim that you've got the best driver already installed, but ignore that.)
After re-installing the Google driver, the Nexus 5x appeared immediately in the Windows 10 interface for file transfers.
Cheers, I hope this helps someone out!

I have the same problem with LineageOS 15.1, I am not sure since when, because I don't use USB that often, but I it must have been after the second update for 15.1. ADB and FASTBOOT don't work.
None of the suggested methods work. I am on Linux, but I also tested the USB driver solution on a windows PC.
The problem is, my phone does not trigger any response from the system I connect it to.
On Linux an lsusb/dmesg shows nothing, and on windows it doesn't make the classic "ding" when I connect something to the USB port.
It is like my phone isn't even there.
In the developer options under networking and USB, USB was set to charging only. I changed that to MTP, but it didn't help.
Now I can't change it back (not that I want to, but just saying). No matter what I press on this menu, it always stays on MTP.
I am here because of adb not connecting tho, MTP is not my concern anyways.
I am not sure what to do, format data, and wipe system etc. and go for a clean install? The problem is, when I boot into recovery, ADB and FASTBOOT don't work either, i.e. my computers don't see an USB connection. So will a wipe even help? I am scared I wipe my phone, and then I can't connect via ADB in TWRP.

Hello @ufopaper
Did you try to cleanup usb connector with a toothbrush and/or a soft plastic tool ?
Did you try different usb wire ? On multiple computers ?

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.
