-Downloaded ADB/SDK again to a different directory, same error
-Updated USB driver and SDK components, same error
-Disabled all firewall/anti-malware/anti-virus, same error
-Rebooted multiple times, same error off boot
-Port 5037 is not bound by any app or process
-ADB, upon failed load, is not listed in Taskmgr, nothing to kill
-Deleted temp files
-Issued at prompt: ADB Disconnect, ADB USB, ADB devices: All return same error as above
-Issued at prompt: ADB kill-server, only prompt returns
Read lots of posts on the web, nothing helps.
I am really interested in a solution and would like to understand what is causing the problem. If in fact it is a configuration issue, where is the ADB config file?
Thanks.
Edit: I am running the command prompt as an administrator.

I originally added my post to this thread in the Nook forum. I don't think there is enough expertise in that forum to help with this problem.
The bottom line is that ADB no longer works and I can't figure out why (see quoted text above). I would imagine that someone here would have an answer for this. Please help!
Thanks.

Only thing I would try it open Task Manager and go to processes and close anything that is adb or adb.exe.

In this case, ADB never starts. It does not work even after a fresh reboot. It is not found in Taskmgr nor Process Explorer.

Is what he meant was to kill any process that is using adb. This is not only a process that is Android related etc. My buddy had your exact same problem because he had his external hd connected to his computer before trying to run adb. Restarting and killing processes that were using adb on his computer did the trick. Hope this helps!

My problem was Windows

In my case, the problem was Windows Vista. From day one, Windows refused to successfully install the USB drivers for the EVO (with the very helpful diagnostic message: "Windows encountered an error installing..."). I have never been able to use adb, and this meant that all the rooting (and update/upgrade) guides that required adb had to be adapted to getting the file(s) onto the SD card, and then using Terminal Emulator (or similar app) to get the job done.
I've just completed a disk-wipe-and-reinstall of Windows on my laptop, and hope to find the time next week to install all the SDK goodies and make sure that the USB subsystem recognizes my EVO. I'm fed up with not being able to use adb, and that, along with Windows Update failing to install over a dozen security patches, finally pushed me over the edge into a re-install. Auuugh! The pain!

Interesting, but I haven't been able to find any other service that is bound to adb and I have no other USB devices connected. Thanks for chiming in though.

For me, I have been able to get two Vista and one Windows 7 computer to work with ADB and HTC drivers the first time. I also have an Epic, and the Samsung drivers installed fine as well (even though they are known to have issues).
Unfortunately, ADB just "broke" one day.
I keep thinking that the Evo community has enough brains and knowledge to sort this out quickly...

Have you updated the sdk recently?
The updated sdk moves the adb files from the tools folder to another folder called platform-tools.
I have adb working properly on both my vista machine and my ubuntu machine hosted on my vista machine.
If you have installed htc sync before uninstall it and the htc driver installer.
Redownload htc sync and the adb files (adb.exe and adbwinapi.dll is all you need). Since adb was working correctly before I'm assuming your java is installed correctly as well.
Reinstall htc sync. When that finishes I suggest a reboot. When you've rebooted uninstall htc sync but leave the htc driver installer. Reboot again.
When you've rebooted again enable usb debugging on your device and connect it to your pc choosing charge only.
This should hopefully reinstall the usb drivers correctly. On vista it installs as adb device or something along those lines.
If the drivers install correctly you should be able to run adb from the directory your two files are in (desktop for example).
If you want, send me a pm with your gtalk username and I can help you troubleshoot it.

Thanks for replying. I had already updated ADB (in platform-tools) before started having this problem. I had also uninstalled HTC sync (reboot, launch ADB w/o HTC sync, same problem) and reinstalled HTC sync, same problem. I updated Java JVM, no change. I then re-downloaded the SDK to a different directory, no dice.
I usually open a command prompt "as Administrator" and run ADB from the directory. Even with a device disconnected, I get the same error. I test this way because if I issued "ADB devices" and it returns nothing, I know it's working. It appears that ADB doesn't even start to the point to poll for devices.
I have, just for laughs, connected my device (USB debugging/charge only), but no joy.
I won't have much time to poke around more until the weekend. If I don't come up with anything, I will take you up on the gtalk. Thanks again.

Windows Vista just makes it all that much harder to fix things...

In my case, I tried all these things and many more (lived with this problem since first getting my EVO on release date in June). No dice, as Windows Vista, once it installs a device driver, doesn't give the user the option to uninstall it (by Microsoft's expressly-stated intent -- a design decision I vehemently disagree with). At least the user could repair such problems in prior versions of Windows by simply uninstalling a device, choosing "yes" to the "remove driver files from the disk" question, and (after the obligatory and ubiquitous Windows reboot) re-connect the USB device. That would start fresh with that device's driver.
I never invested the time to learn how the USB subsystem registers devices and their drivers (in Windows Vista) in order to determine how to manually remove a driver from the Windows Registry adequately that it would treat the device as "new hardware detected" upon the next connection.
Once Windows Vista has scrambled some internals in the database/registry controlling the USB subsystem's driver knowledge, you're toast. Nothing I could find in Microsoft's Knowledge Base nor MSDN shed any light on how to tackle the removal-and-recreation-from-scratch of the USB system configuration.
Microsoft's stock answer was invariably "re-install Windows". Yeah, thanks for that. Windows, even more than 26 years later, is still not a real operating system, and still has bugs dating back to Windows 3.1.
Sigh.

Check Windows Firewall service.
In my case I just turned off the Windows Firewall and it started working.

I accidently figured it out
so i was trying to find my cid number because i was flashing ICS firmware and stuff, and the adb deal in the prompt kept giving me the exact same error, and thus would'nt work. after trying everything (such as: installing drivers, killing the process, restarting my comp, reinstalling adb, etc.) for about an hour and a half, i just stumbled upon a page that was linked to in the ICS flash guide, that had a different adb folder download. this download has an entirely different effect on the command prompt and worked so i could get my cid number and rewrite superCid. here it is:

[Q] USB ADB drivers do not install! Help please?

I am unable to get USB connection working with my phone for development purposes. I have turned on the USB debugging and connected the device with USB cable and it does detect file transfer capabilities, but I am unable to get the ADB connection working.
I am running Windows XP SP3
It says it has found a device 'Galaxy' but is unable to install drivers for it.
What I have tried:
sdk/extras/google/usb_driver directory
I tried installing PdaNetA302.exe
I tried installing Samsung_USB_Driver_for_Moblie_Phones_v1_4_6_0.exe
I selected 'install from specific location' -> choose a driver -> 'Android Phone' but it had none listed and the aforementioned driver directories did not work either when I selected them as 'Have Disk' options.
I also tried uninstalling all related devices and do the whole connecting thing again, but without success.
Help please?

SOLUTION
Apparently HTC drivers got in the way. After I removed all HTC drivers from my Windows XP, restarted and connected the device, the Samsung drivers kicked in and made it work.
To remove unused drivers from Windows XP you can follow this guide.

Thanks for posting your experience.
Another problem I found, was that there's a different SamsungDriver.exe floating around, 8341kb. DOES NOT complete the ADB drivers necessary.
After installing the v1.4.6 drivers mentioned above, golden!

Spoke too soon.
ADB recognizes it when it's booted in ICS, but while in the bootloader, it's not picked up. Thus fastboot commands won't work!
Windows 7 gives me a Android 1.0 driver not installed error.
Anyone?

PdaNet

I had no end of problems getting adb and fastboot working for GN due to the usb driver problems.
After much Google-ing...
I installed PdaNet on my laptop and this installed all required drivers in the process of installing, you can then un-install PdaNet and the required drivers are still on your system.
I now have adb and fastboot working for both my Nexus One and Galaxy Nexus phones on my Windows 7 x64 laptop.
Hope this helps!
Thanks to XDA member el3ctrik for this tip!

Thanks, figured it out just after you posted. The PDANet drivers were the trick, in #3 below (don't need to actually run the installation in this case).
You'd think after 1.5 years of playing/hacking/unhacking/fixing and refixing the N1 I'd know how this is supposed to work.
A couple of comments, since some tutorials are based on older installations.
1. Installing android sdk. I went through a crapload of unnecessary trouble in trying to reinstall these, thinking that the usb drivers, adb, and fastboot needed to be updated. NO.
1a. In fact, in trying to reinstall the android sdk, you have to install the Java SDK. THEN, with the latest revision, R15, FASTBOOT IS MISSING! Need to pull that from a r13 zip.
2. You need the CORRECT samsung drivers. The ones mentioned above are the correct ones. I installed some limited half-ass versions which did not do the job.
3. You need FASTBOOT drivers. These were found from this post http://forum.xda-developers.com/showpost.php?p=9919944&postcount=1
which states:
http://www.fileserve.com/file/5bgRBX5 (PDAnet x86 and x64 which are the fastboot drivers plus android sdk drivers)
The #2 drivers let ADB see it when ICS is running, #3 (and probably #2 too) are needed while in fastboot. To get #3 installed, I had to go to device manager in Win7, hit update driver (next to the error exclamation mark device), and direct to these files.
That is all <whew!>

Glad you got it sorted out buddy, I was in exact same boat, years of Nexus One fastboot and adb use, but still had problems!

I am really struggling to install ADB drivers (for using within ICS). The GNex is in developer debug mode. When I plug in, Device Manager shows the Portable Device, but no other devices are shown. So in this case, i have nothing to right-click to manually install the drivers. There is nothing under Android, or adb, or anything like that. Hope someone can advise...
I got it to appear by changing to PTP mode in the USB Computer COnnection on the phone!! Success.

Windows 7N USB driver issues
First post on this forum, so please bear with me.
I struggled for a few weeks trying to connect my new Samsung Galaxy Nexus (Rogers) to a 32-bit Windows 7 Ultimate N machine. The system wouldn't accept the drivers from Samsung - failed to recognize, driver software not successfully installed, etc. Tried all variety of proposed fixes, manually selecting the driver (have disk), downloading SDKs and ADB drivers.
Finally fixed it based on a very old suggestion from several years ago from an HTC user. The USB driver wasn't recognized in the absence of Windows Media Player being installed on the machine (a quirk of Ultimate N). Found the Patch from MS for WMP for 7 Ultimate N and the system immediately recognized and installed the Samsung driver and thus the Nexus is now connected.

Download my toolkit (ROM-Less), it will assist you in that manner!
It has easy instructions, and it will do most of the work itselff!

AT&T S3 not seen by ADB

Ok... i've gone through the steps in the one thread to get the phone rooted and everything without tripping the flash counter. At least the rooting with ODIN part. Been trying to flash CWM Touch for it, but for the life of me can't get the S3 to enter debugging mode over USB so that it can be seen by ADB to do so. I have Debugging over USB checked in the settings on the phone, i've rebooted the phone several times... it just never seems to enter debugging mode (or at least not like on my old Atrix 4G, where it actually told you in the notification bar that debugging was enabled).

It doesn't say debugging enabled. Do you have Kies installed? If so make sure it isn't running. Plug in the phone and type adb devices. If detected adb will report a serial number.

I had installed Kies... tried hooking it up, still wouldn't list in ADB. uninstalled Kies, but kept the drivers installed. And i only mentioned the idea of it saying Debugging enabled when you connect the USB cable because my Atrix 4G said that every time from the get-go.

Also odd.... looked into the SuperUser app... and the log shows several allowed access attempts from "shell"... yet never seemed that way in ADB.

I had the same problem... try going in to the "services" settings and update the driver to Android ADB composite. Other than that, my suggestion is to make sure Kies finds the drivers for both Camera mode and USB mode by toggling the selection while plugged in to Kies.
Sent from my SGH-I747M using xda app-developers app

Your last resort would be to remove the drivers and reinstall them... Don't install Kies...

Or do you think i might have better luck in Ubuntu? Have that installed on my desktop as well.
edit: well... that's odd. booted into Ubuntu, installed the linux Android SDK and everything, got everything set up. opened the terminal, and just checked the devices without being in the ADB Shell... and a device showed up. launched the adb shell... checked devices again... nothing showed up, as on Windows. Figured what the hell, and did the command to install the recovery, and it worked.

It seems to be a driver issue, kies interfering, or a component is missing, or all of that, so I'd start your windows driver and software over fresh...
Uninstall Kies
Uninstall the drivers
Reboot
Install the drivers
Install the Java JDK (64bit has never worked for me, even though the drivers are 64bit)
Install the Android SDK
Use the Android SDK to get the Platform Tools and the Google USB Driver
than adb devices should show a phone

sometimes ADB Devices returns nothing for me, but theres a phone there, it would say nothing connected or to some effect if it didn't find anything...

Yea... every time i entered "adb devices" in the Windows command prompt, it always said "List of detected devices" or whatever it says, but nothing would be there, and if i tried the command to install the recovery it would say it was not a valid directory or whatever. Didn't show up on Ubuntu either, but it still worked...

EDIT/UPDATE: I was using a USB 3.0 port which apparently ADB didn't like (though ODIN rooting on that USB port worked fine...). I switched to another USB port and suddenly it worked!
Sorry to resurrect an old thread but I guess it's better than creating a new one for the same purpose...
Doesn't seem like this was resolved and I haven't been able to get my S3 to connect to ADB. I'm running Windows 7 Ultimate 64 Bit.
I had this driver already installed:
ATT_I747_GSIII_Samsung_USB_Driver_v1_4_6_0
I enabled USB debugging and it wouldn't connect. I installed Kies, still wouldn't connect. I uninstalled the driver and Kies and rebooted. Reinstalled "ATT_I747_GSIII_Samsung_USB_Driver_v1_4_6_0", installed the Google USB driver, still won't connect.
I'm still not sure if I'm supposed to see any sort of notification in my bar showing that USB debugging mode has been executed but I'm definitely not getting anything like that.
Code:
D:\APPS\ANDROID\android-sdk-windows\platform-tools>adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
891b0876 offline
D:\APPS\ANDROID\android-sdk-windows\platform-tools>adb devices
List of devices attached

Yea, when i finally was able to use ADB to push a recovery onto my S3, it never actually showed up if i checked the devices in ADB Shell. Well... it DID, but not if i already typed the SU command before "adb devices".

so whats left? i have my phone usb connected to comp and debuging on i type adb shell it says adb is not recognized internal or external command???
do i need to have somthing open on the phone b4 openning command?

You need to navigate to the folder where adb is actually located (platform-tools)

You don't have to use adb, you can use the same commands on terminal emulator

sm3 driver

hello guys, just bought that amazing watch today i have an issue. How can i connect it to my pc ? I plug in the usb, while sm3 is off. Win7 start to install and at the end it fails because of the drivers. So my pc doesn't recognise it. I can only see the "empty" E:/ Disk. Any suggestion ?

edit: unistalled the "watch" and then plugged in again and drivers get istalled. Now i have a "sony file-cd usb gadget" . help me pls
edit: wrong section :/ sorry

I have exactly the same problem.
i installed the Google USB Driver from theAndroid SDK Manager and also installed the Sony PC Companion. But the Smartwatch 3 still shows in the device manager under "other devices" without installed driver.
The only way i could connect to it is using ADB over Bluetooth which is really slow.
Anyone any idea?

i used these adb drivers http://download.clockworkmod.com/test/UniversalAdbDriverSetup6.msi
after installation, i went to device manager, update drivers, search pc for drivers, choose from a list of...., and then i selscted adb testing interface version 3.12.0.0
i had to skip the warnin popup, but adb is working fine

Thank you a lot.
i could not find any "adb testing interface" so i installed "Google Nexus 7 ADB Interface" from the list and so far it seems to work with that too.
Not sure why you have such a testing interface driver.

Did this HERE and no driver problem for me.
Drivers can be found in this folder : Program Files (x86)/Sony/Sony PC Companion/Drivers/

The Driver used in the bootloader is a different one. I have no issue there.
But it seems there is no actual ADB Driver used when the device is in normal operation mode for debugging apps or pushing apps directly over ADB on to the device.

How do I install Huawei Watch drivers for ADB? [solved]

Hi
ADK is working fine with my other devices, but my PC can't seem to install the drivers for Huawei Watch. The devices is in the device manager, but a little yellow triangle at the side, which means the device drivers are not installed.
I have tried Google, but the guides just say install the devices drivers but clicking update in Device manager with the xx file I downloaded, but windows can't see the file.
Thanks in advance

but the installation cannot continue.. did u success installing pdanet ? what version of your windows u have ?

why is this marked as solved because i dont see the solution. i just received my watch today and cant seem to get device manager to recognize any drivers.
PDAnet doesnt fully install because i cant install drivers
Minimal ADB and fastboot dont recognize any devices attached
Universal Naked driver 0.73 doesnt work even after modifying the android_winusb file
I even installed the Google USB driver from the SDK Manager, but i dont see anything on my machine.
ive had this watch for 2 hours and already frustrated as hell lol. can someone provide assistance?
thanks!
PS. im running this on Windows 7 64 bit and the watch is at LCB43B already

i was trying all day on my work computer which runs windows 7 x64 with no luck, but the watch was detected immediately on my windows 10 machine at home. strange.

Success!
I fixed my issue! I had the same issue everyone here mostly had. I could unlock the bootloader, but I couldn't get the Fastboot recovery to work because the drivers were not detected by Windows 10, or my other Windows 7 machine. Both machines installed a standard version of Google Android device drivers and boot loader drivers, but they were not detected by ADB commands once in the bootloader.
First I went here to download all the drivers, but got stuck:
http://www.thecountrycaller.com/37260-how-to-unlock-huawei-watch-bootloader-and-flash-twrp-recovery/
So what I did was ran the commands to reboot to bootloader, then flash commands for the recovery, left my device plugged in. Then I went into the Windows Device manager, and looked for the Android or Adb drivers loaded. I double clicked the driver, and clicked on uninstall driver, and told windows to delete the drivers. I then unplugged my device (still in bootloader mode), plugged it back and in windows instantly detected the ADB flash commands and boom, TWRP recovery completed.
Hope this helps some of you.

this did not solve my issue ive installed the drivers and nothing over and over can someone help me with the drivers please
thanks
running windows 7
tried to install every driver possible
