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.

[GUIDE] FIX for broken USB and ADB in windows with CM7 Builds. Tested and working.

All credit goes to oc3rulz for finding this.

Now again I am using Windows 7 so the steps are almost exactly the same. I literally just changed the device to a USB Mass Storage device and it worked!
Lol after trying so many drivers and it being the generic driver makes me angry. Here's what I did.
1. Right click on My Computer, go to Properties.
2. Go to Device Manager
3. Find your My HTC (should be the second one Android USB Device), right click on it and select Update Driver Software
4. Then select Browse My Computer for Software
5. Then choose Let Me Pick which driver to install on the bottom.
6. Then choose USB Mass Storage Device
Then it takes some time to think and viola! All working! However we are not DONE!
EDIT: So the next step I did after experienced issues remounting after unplugging the phone. I have change the MTP to ADB Testing Interface and things seem to be mounting everytime. Rebooted phone and PC, both worked again so I think this may be a working solution.
Now go to MTP.
1. Right click on My Computer, go to Properties.
2. Go to Device Manager
3. Find your MTP (should be under Unknown Devices), right click on it and select Update Driver Software
4. Then select Browse My Computer for Software
5. Then choose Let Me Pick which driver to install on the bottom.
6. Then choose Google Inc. and the Driver is ADB Testing Interface.
ENJOY!

Thanks ALOT
This definitely work I was gonna blow up my Windows computer, but this saved it... lol

I did something similar to that cuz I couldn't find some of the stuff when I choose "let me pick." But at the end I have two drivers under Android Phone that says the exact same thing in device manager and everything works!

Sorry but what is MTP?
I don't have Google Inc in my list?

I have both Mytouch4g and MTP listed in Other in device manager.
I also don't have Google Inc in my list? Can someone tell me how to get Google Inc in the list?

I'm on XP and I show two devices labeled Android ADB Interface. When I go to properties, the location for one of them shows LOCATION 0 and the location for the other shows LOCATION 0 (myTouch 4G).
Which one do I want to uninstall/change drivers for?
Btw my computer detected the device just fine on it's own and adb works but mass storage doesn't. Maybe I should just leave well enough alone?

Try the mtp steps first guys. That worked for me. Also, before doing the mtp steps I only had to go to adb interface then select Google Inc then adb interface again. Netbook with win7. Wtf is starter? Lmfao

I dont have xp i have windows 7. it took me a couple of tries but i just kept uninstalling and reconnecting the phone so that the devices show again. for the htc driver I pick mass storage just like he said after update driver. For MTP i had to pick android phone and then pick adb usb driver and it worked. I didnt want the mytouch one just sitting there without it working so i searched for a driver for that and picked the htc driver for that.. it all works!! thanks option94

htc keeps asking for MTP driver?

Dezire z keeps askinf for MTP drivee?? i recently flashed mexdroid rom, and in the beginning none of the usbs would connect my phone. I thought it was a nightly issue as it was based off of a nightly but now its using RC1.
Recently i played around, it wouldnt connect with the "ADB or Android phone driver." I fixed that and those work fine in Device Manager in Windows 7. However!, in device manager it KEEPS asking for MTP. i tried uninstalling, updating, everything!! and it just wont find my htc desire z.
ADB can find it when using command prompt. It can even logcat, and its weird why ADB can see it but windows cant. I have posted a Download link to the Logcat file. Im hoping anyone here can help me.

thanks
edit* i think i read somewhere Android doesnt use MTP drivers....-confused-
windows 7 can see my phone and lets me safely remove it too, but wont let me see it in my computer.

issues I was having with W7 x64 were resolved by PDANet. you might try it out, although your issue is slightly different than mine... the device was entirely unrecognizable (by adb, fastboot, the whole shebang).
edit: NOTE you don't need to actually use PDAnet, it will just locate an appropriate driver and install it for you, then you can uninstall it from your PC.. unless you want to use it, of course. pretty slick.

ive done this and it found the proper driver. "Android phone" BUT when it tries to connect with device, it says "failed to handshake with device" and proceeds to uninstall pdanet. Is it because its conflicting with windows 7 cant find the MTP driver?.... sooo confused.. never, ever had this problem
edit* after pdanet is uninstalled, the Android phone driver works fine, but MTP does not.

that's a bugger.
when you plug the phone in, in device manager, does it show as a USB mass storage device under the USB controller section? to check: unplug all usb devices (aside from input devices like keyboard/mouse/what-have-you). plug in your phone and go to device manager (right click my computer->manage->device manager). under USB controllers, check and see if there is a USB mass storage device. assuming you have disconnected any other storage media, this is your phone.
if it does:
uninstall this driver, unplug your phone, restart, plug your phone back in.
if it doesn't:
my next step (take it for what it's worth - I'm sure there's an easier way) would be to unplug all usb devices (including keyboard/mouse - anything USB related), uninstall EVERYTHING under the USB Controller submenu, then restart and plug the phone in.
W7 should automatically recognize and reinstall the USB host controllers and hubs.
edit: are you using any other USB storage devices? thumb drives, ext harddrives, etc? do they work?

Under the usb section in device manager, i have about 8 or so usb controllers and stuff. Im using a Gateway Laptop and only one thing is using a usb port--- the mouse. Thats all. So i dont really have a clue which one is my htc phone because when plugging it in and going into device manager the only devices i remember using the phone were adb, android phone, and Now MTP. If i could pinpoint which usb controller is using my phone ill uninstall it. Other than that, what else is there? This is the strangest problem ever

Have you tried the drivers from the official HTC Sync software? Also, are you actually trying to use the phone as an MTP device or as a USB mass storage device? I don't think you can use both at the same time (though I don't use this ROM so maybe things have changed). If you don't actually want the MTP functionality, I wouldn't worry about it.
Also, I noticed the notes for the ROM says "USB mounting is not working on a Windows OS computer" is a known issue. Not sure if that could be related...

windows 7 home doesnt have that script gpedit.msc
i looked all over google and it doesnt work . only pro and business versions have it.

Did the HTC Sync software not work? Also, have you tried formatting your SD card? Might be a long shot, but if it was ever used in MTP mode at one point, maybe your comp is detecting the files and thinking it's still an MTP device. Not sure if it works that way though...
Did you ever set the phone to MTP mode in the past? Like if you were ever on a Sense-based ROM. Maybe if you had it in MTP mode prior to flashing the new ROM, it stayed in it. Once again, no clue if it works that way since I've never used MTP on this phone before, but might be worth trying if you are out of options.

STILL havent fixed this MTP driver issue, have tried everything including the post above me!....NOTHING IS WORKING. why is it being recognised as mtp, when all i need is use the sd card.

this has been up for a week, seriously no one knows how to fix it?

I'm guessing it's because no one else has encountered this problem before...
So what happened when you flashed back to a Sense-based ROM? I've never used one, but I thought when you connect the phone via USB, you have to choose what kind of connection you want (e.g., HTC Sync connection vs Disk Drive). Are you saying even when you choose to connect as a drive, the phone still shows up only as an MTP device (which I'm assuming is what is used when in HTC Sync mode)?

Well either Windows sees your phone as an MTP device or the phone is actually reporting itself as an MTP device (not sure how it works on phones, but typically Windows communicates with firmware on a USB device to determine its classifications).
I'm guessing you already tried this since it's one of the only threads on the G2 forum when I did a search for MTP...

[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?

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.

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.

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.

[Q] HTC M8 not being seen in adb

OK using a windows 8.1 Pro laptop, ADB installed properly with HTC Sync Manager, both Windows, HTC Sync Manager and the Device Manager in the Control Panel can see my phone. I tick on USB debugging and then press revoke USB debugging authorizations. Unplug my phone and plug it back in. I'm using the original USB cable from HTC. Everything pops up and shows like it's connected, except when I type in
Code:
adb devices
in the command prompt, then it just comes up blank. I've attached screen shots so you guys can see what I am talking about. If you have any ideas it would be much appreciated. I've attached some photos just to show that I've dotted all my i's and crossed all my t's as far as I can see. I also want to point out this is the second computer I've tried this on.

Might be a driver issues... Try those: https://www.dropbox.com/s/nr91z4bveeugaow/googleUSBdrivers.zip?dl=0

1) Unplug the phone from your computer
2) Uninstall anything related to HTC (drivers, sync managers..)
3) Reboot the computer
4) Install the latest (direct URL) HTC Sync Manager
5) I tend to uninstall the manager right afterwards (optional)
6) Reboot the computer & plug in your device
7) Report back

Yeah that didn't work, I even tried installing the USB Driver manually and that didn't work either. Still comes up as not connected, it's super frustrating.

Not sure if this helps but for some reason my Android Phone isn't showing up under Android phone in my Device Manager, it's showing up as Portable Devices. I don't know if this is an issue or not, anyone care to give an opinion?

That's normal as the phone is using MTP, the Android Phone entry only appears once the drivers are installed. It's definitely a driver issue but as to what I can't say as I have no issues on my 8.1 Pro laptop

I think I figured something out, just flash CM 12 - (God it's amazing. ) and now I can see my phone on ADB, so whatever ****ery was going on I am blaming it on HTC stock rom.

is cm12 worth the hassle?

Sorry for the necrobump, but I ran across this thread while researching the same issue on my M8 and wanted to save anyone else the trouble if they also stumbled across this same issue.
Though the solution discussed would likely work, if you don't want to hassle with a new ROM, it is possible to fix it on your existing ROM provided you have root.
[SOLVED] ADB 'unauthorized', no RSA prompt, and no 'Revoke USB debugging' option

Thanks for this guide you put up. Interesting that there was no option for you to revoke USB authorization. My device is S-ON and have been using Viper for a while with the option available. Same for HTC stock. Good for you getting that fixed. Had a similar issue on a different device months ago.
