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.

lol, I did all that a few times, but im sure its not an incompatibility issue. probably just a skipped step somewhere.

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.

"Hardware ID doesn't match" error when plugging phone in

Okay, this is the second time this error has popped up and it's starting to get on my nerves. Anytime I plug my phone into ANY USB port, and this is counting both 2.0 and 3.0 ports, I get the error bubble: Hardware ID Missing. Windows cannot identify the device plugged into the SAMSUNG Mobile USB Composite Device." Honestly, this is beyond irritating.
For one, I am not going to reinstall Windows 7. That's too much hassle for this. Second, ever since someone plugged their Droid into my USB cable so they could charge up their phone, this message started appearing. I tried to reinstall drivers (Samsung driver exe said it couldn't install), uninstall, disable, etc etc, but finally managed to get the damn computer to read it when I stuck it in the 3.0 USB port. Now, just 10 minutes ago, I plug the phone in, I get that error, on a 3.0 USB port.
So, now I have no idea what is going on, nor how to fix it. I've tried searching, but there are no answers. Or, the possible "solutions" don't even work even remotely close.
I could really use some help on this. And, again, please do not mention "Reinstall Windows". That's just too much of a hassle and I'm not going to do that.

You may not want to try this either but try a system restore

I had the same issue what ended up fixing it for me was watching when I plugged the phone in after a clean driver install and stopping Windows from downloading and installing an updated driver. Dont know if its the same for you but that fixed it for me. I was really frustrated by it and found no help either.

probably an easy fix
definitely don't need to reinstall windows or do a restore. But just to be sure, you don't have kies installed right? Seems to cause problems.if there's no kies installed, go into the device manager and find your phone whatever it's listed as right click and uninstall. Check the little box that says, "delete the driver software for this device". do this for any devices relating to yours. Including the stuff under modems,ports,USB controllers.and tick that box that delete driver software for this device every time you uninstall something. Now, not saying it's necessary but wouldnt hurt, reboot the pc. Then with your phone unplugged, reinstall the Samsung drivers for the phone. Now to make sure windows doesn't DL its own drivers,disconnect from the internet and plug the phone back in. Should be all good.

I won't do a system restore, that won't do anything. Not to mention it would erase some programs that were installed (not related to phone). So, not doing that. Also, my computer will not automatically update any drivers or any thing else, as I have it set to manual mode.
And, I do not have Kies installed. It never worked for me properly, when it came to driver installation. I've done the "go into device manager" bit many times before, it still likes to play the "Hardware ID doesn't match" card. Drivers won't install either. I don't know what it is, but damn this is the most stubborn thing I've ever encountered.

i've post this in other forums today. what i do to get it working is i toggle USB debugging and try it out, then start toggling the ptp and mtp until it works. the combo that works for me is turn on debug, plug in computer, unplug, turn off debug, plug in. if it doesnt work then i toggle back and forth MTP and PTP. 5 tries at most, for me. Also, i did a nandroid back to my oem ICS that was 2 weeks old and just rooted. the problem is worse there. i'm using freegsmr6 with trinity kernel on Tmo. hope it helps.

Yeah that whole "Hardware ID missing" was an irritating situation. This is what I recommend as far as making it work.
1. Plug in.
2. When you get the error message, I think its because of a conflict with the ADB interface. Go to Settings, Developer Options, and check off USB Debugging.
3. Plug in once again and it should work. If not, try toggling between Camera and MTP.
I have Windows 7 Ultimate and it works fine for me

I always get that error as well with my SGS 3. I have to reinstall Kies everytime it does that which is annoying.. ANyone has a permanent solution about this?

Fix for me was...
1-plug in phone. Get the hardware ID message. Leave phone plugged in.
2- open device manager. Click on. Android Phone and Uninstall Samsung Android ADB Interface. Also check the "delete software driver" when the dialog box shows.
3-still in device manager. Scroll down to Universal Serial Bus Controllers. Uninstall Samsung Mobile USB Composite Device.
4-unplug phone.
5-reboot pc.
6-install SAMSUNG USB drivers from their site or from here
http://www.epiccm.org/2012/06/cwm-recovery-on-all-sgs3-lte-variants.html?m=1
7-reboot or not. Plug in phone.
This worked for me and no issues for the last 6 days. YMMV..

this works!

Hardware ID missing - SOLVED!!
1. Uninstall any previous instance of Kies/USB driver
2. Download the latest Kies, specific to your S3.
3. Download Samsung USB drivers 1.4.6.0 (I've tried newer versions but they all failed)
4. REBOOT
5. Disconnect from internet (VERY IMPORTANT!!! - forcing Windows to install local drivers ONLY)
6. With the phone disconnected, install Kies + USB drivers downloaded in steps 2,3
7. Connect the phone and let Windows install the drivers.
8. Reestablish the internet connection.
I've done just that, I've connected my S3 to the PC several times, I've also rebooted twice and I've never seen that stupid message again - while of course everything works as expected.
:good::good:4 days later, several times rebooted (phone and PC), several connections with Kies and I have NEVER seen that error again - it works!!
UPDATE!! (Oct.11.2012)
After a few Kies updates and going through various ROM's:
- the procedure listed above works 100% but a few steps are just not needed (redundant) - see bellow
- the problem is mostly caused by Windows "forcefully" trying to install its own drivers, rather than allowing Samsung's suggested.
- Samsung's fault is providing "updated" drivers that don't always work (hence, use the suggested 1.4.6.0 drivers)
- Following EVERY Kies update, DISCONNECT from internet before plugging your phone (otherwise you'll have to go through this, AGAIN).
Some suggested here that plugging the phone into a different USB port (without disconnecting from internet) would be the culprit - which happens to be true, but as a mere effect, not the cause: every time an unknown device is plugged into a different USB port, Windows is trying to download/install the appropriate drivers if it doesn't recognize the hardware - and there you are again.
So, the simplified procedure becomes:
1. Not needed - leave Kies installed, as is - no harm at all
2. N/A
3. YES
4. Not (always) required
5. MUST
6. MUST
7. MUST
8. Yes
Furthermore, if still interested in connecting your I747(M) as UMS (USB mass storage) the solution presented here works. I tested it myself - read my comment on this post for the very few existing hiccups.
- while installing the USB mass storage device drivers you don't have to disconnect from the internet

Install Drivers
Have you tried just installing the drivers directly from Samsung? That is all I did when I had problems and it worked.

For someone experiencing the "hardware ID missing" error, just reinstalling the drivers won't do anything. Like many others, I've been banging my head trying to solve this for quite some time; the suggested steps are truly a compilation of successful ideas and trials mingled with tons of frustration, coming from my own experience as well as from many different people and forums.
If, on the other hand, you had a different type of connectivity issues - without this error, then, yes, reinstalling the drivers is Samsung's recommendation.

Just wanted to say thank you. Did this and the last 2 days, works everytime. I made sure that after the first time I plugged the phone in after doing all this, and the screen pops up asking what I wanted to do, made sure to check the box for "do this everytime" and then choose the view folder option or whatever that is.
Thank you again,

One thing I have tried which might help others - I had the Android Developers toolkit installed on my machine, which I've removed and I also removed the HTC Sync software which was for my old desire.
Rebooted, installed the SG Toolkit (can't remember which post I found it in) and then chose option one after selecting firmware to install drivers.
I cancelled the "Windows Updates" bit of the driver detection and it found the first item, and had "item disconnected" for the remaining three.
Unplugged and plugged back in and voila it works.
This worked for approx 5 mins and then stopped, however I did all the above with debugging on, debugging is now off and all seems well (touch wood). However looking at putting on a different kernal to expose storage as mass storage and also get around cifs issues.
Hope this helps someone.

The Android Developers toolkit DOES install the USB drivers 1.4.6.0 - which seems to be the ONLY one that works, BUT the rest of the steps suggested in my previous post are needed in order to get rid of the problem - otherwise the fix is just temporary.

I removed the updates to Kies on my Note and uninstalled the Kies update on the PC which is what started this issue of the OS not recognizing the device and then a fresh driver load for my phone from the Samsung site. Worked Perfectly, Thanks!

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.

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.

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.

[Q] Can't update Drivers

Hey guys,
I've been wary to flash the ROM of my Nexus 7, as it actually boots into the normal OS and does everything fine.
The basic problem is that I can't transfer anything to and from the device over USB. USB debugging is on and I have tried PTP and MTP.
One of the solutions I have been looking at is bad drivers on Windows' part, and that is where I am currently blocked. If USB debugging is off, Windows refuses to acknowledge my tablet's existence. If debugging is on, some drivers from Microsoft automatically install and the tablet is labeled as "unknown device".
My USB controller is up to date with the correct drivers provided by ASUS for my motherboard (ASUS Z87-A). I recently re-installed Windows 7 to put it on a larger SSD, and with this same motherboard, it now does not detect correctly.
If I try to uninstall the "unkown device" it simply disappears until I unplug and replug in the tablet. If I try to manually direct it to the correct drivers, it tells me that the USB drivers are incompatible with my device. The USB drivers are the ones downloaded directly from Google.
I can still access the fastloader.
If you need more information, just let me know.

When you first got the device, did you go straight into fastboot without booting it and plugging it in while in Android? Does that question even make sense?

One of the solutions I have been looking at is bad drivers on Windows' part, and that is where I am currently blocked. If USB debugging is off, Windows refuses to acknowledge my tablet's existence. If debugging is on, some drivers from Microsoft automatically install and the tablet is labeled as "unknown device".
My USB controller is up to date with the correct drivers provided by ASUS for my motherboard (ASUS Z87-A). I recently re-installed Windows 7 to put it on a larger SSD, and with this same motherboard, it now does not detect correctly.
If I try to uninstall the "unkown device" it simply disappears until I unplug and replug in the tablet. If I try to manually direct it to the correct drivers, it tells me that the USB drivers are incompatible with my device. The USB drivers are the ones downloaded directly from Google.
I can still access the fastloader.
If you need more information, just let me know.

Use this as a possible quick-fix (not all mode combinations will work right): http://download.clockworkmod.com/test/UniversalAdbDriverSetup6.msi, then reboot.
Use this as a more complete fix (recommended in your case): http://forum.xda-developers.com/showthread.php?p=50253887#post50253887

When you first got the device, did you go straight into fastboot without booting it and plugging it in while in Android? Does that question even make sense?

That would have been roughly a year ago. I believe I did boot straight into the OS.

To the first quick-fix, the ADB drivers are installed, but they are not the drivers that are utilized when the Nexus 7 is plugged in. Like I said, it instantly installs some generic Microsoft drivers, and refuses to recognize the ABD drivers are compatible for the device.
As such I can't even begin with option 2.

With the device plugged in, go into device manager and find the device, uninstall that device, and make sure you check the box to uninstall the drivers from the system, then leaving the N7 plugged in to the PC, reboot the N7, as it comes up it should redetect, it's important to leave the device plugged in while it is rebooting.

There is no check box to uninstall the drivers: imgur.com/PhL4UNt
Where "unknown device" is my N7. Still, I tried rebooting it while leaving it plugged in, and it would not recognize correctly.

You may want to make sure you are not using a hub or USB 3.0 port for this btw.
Put the device into in MTP mode with debugging on, unplug the device, then download these, unzip them somewhere, right click on the unknown device associated with your Nexux 7, click Update driver software, click "Browse my computer", navigate to where you saved the unzipped contents, and select usb_driver folder, let it do its thing, reboot your PC. Plug the device back in, preferably into a different USB port then what you have been using, it should then show up as a Google ADB driver (or similar), you can test it with the command: adb devices see if that works, if not, leave the device plugged in, and reboot the device.
Let me know if that works or not, and I will continue in a new post.

Ok, plugged directly into a USB 2.0 port at the back of my motherboard. Recognized as Unknown Device when plugged in, disappears completely when unplugged.
So, here's exactly what I did: Plugged in device -> clicked on "Update Driver software" -> unplugged device -> Browse my computer for driver software -> directed to correct location -> replies: "The best driver software for your device is already installed", and it is not using the ADB drivers.
Going into "Driver Details" tells me that there are no drivers that have been installed.

Don't unplug the device, do like this, put it in MTP/debug on, leave it plugged in, "Update Driver software" -> Browse my computer for driver software -> direct to correct location.
I know my method works, I've done it to that laptop, my htpc, and my gaming rig flawlessly.
You may have to use a tool to remove all instances of those drivers and reboot, Wugs toolkit has the app, let me see if I can find the direct download for the app or you can just download and install Wugs Toolkit.
Here is the app, but I'd still recommend you install Wugs NRT, as the kit has a walk-through telling you which device IDs to look for to remove. Here is the actual tool wugs uses: http://www.nirsoft.net/utils/usb_devices_view.html, but again, unless you know which ones to remove, you're better off using Wugs tool kit device drivers walkthrough built into NRT.

Well, NRT is precisely where I started this whole thing.
Here is a picture detailing where the Nexus 7 is connected, and for reference, ALL the USB ports on my case, be it at the front or from the motherboard, are controlled by a hub: imgur.com/pP5ZbMv
Every other device's location is described as "Location 0" except for the Nexus 7 when it's connected.
Unfortunately at this point I'm probably just going to use Dropbox to transfer files when I need to.

I guess something is trashed in your system, maybe using a previous motherboard driver would work, dunno, sorry it didn't work out.

Well thank you very much anyway. I'm sorry I couldn't have been more clear initially.

No problem, maybe you'll work on it again and you'll figure it out. Also, you can use airdroid for transfer of files, I hear it works really well.

Device not recognized by PC

I have windows 8.1 and my pc does not recognize my m8. It is connected and charging though, and I am using a USB 2.0 port. USB debugging on. On the device managers, no device shows up. I uninstall all HTC Drivers aswell. Any help? I just need it to have a yellow explanation mark device on device managers, and I know what to do from there.

I tried download HTC drivers but the htcdriver.exe won't bring up an installation window. I'm running out of time as I need to return to stock quickly before Wednesday.

Try this solution.
[Q] Device not recognized by Windows 8.1

Have you tried different cables and usb ports? A different pc as a last resort?

Make sure you have no other phone drivers installed (Samsung, etc.) and make sure all HTC drivers are uninstalled. Make sure you don't accept the option to automatically install HTC Sync when you connect the phone. After that, you should get the yellow exclamation point in Device Manager. Select the option to manually select the drivers, and pick the generic Android MTP device (or some similar description).
