ADB Drivers for EVO?

I have been doing Android development for a while on my work laptop that runs Windows Server 2003 64bit. Previously I've used a HTC Magic (AT&T) and a Moto Droid (Verizon) for development. Now I also have a EVO that I am trying to use. The problem is that I cannot get ADB to work with it.
System: Windows Server 2003 64 bit (work laptop, no I cannot put Windows <whatever else> on here).
Phone: EVO
Since I have been doing development for some time I already have the SDK, along with the USB drivers.
Here are things I have tried:
1. Plug in EVO. It wants to install ADB drivers. I choose the USB drivers location. Fails.
2. Delete USB Drivers. Redownload them from the SDK. Plug in, choose drivers, fail.
3. Plug in, allow drivers to fail, I have the ! in device manager for ADB. Unistall the ADB driver. Scan for hardware changes. Install ADB drivers. Fail.
4. Uninstall the Motorola USB Driver package. Try all above steps, fail.
5. Try to install HTC Sycn, Server 2003 not supported, fail.
What else can I try to get ADB working? Seems funny that it would work perfectly with a HTC Magic and a Droid but not this EVO.

Eureka! I found an obscure post on some crappy forum to a link for what someone called HTC Evo 64 bit drivers, so I thought what the hay, lets try them.
http://depositfiles.com/en/files/yd61xorii
The folder of drivers in there was really called Vista x86 but, still worth a shot.
It worked perfectly. The phone doesnt say ADB in device manager now but "My HTC". ADB is working fine.
Hopefully someone in the same boat as me will happen across this and it will save them time.

Thank you! Saved me a BUNCH of time! You're the man!

The file appears to be unavailable on that site now, could someone please re-host this ASAP? I can't get anything else to work and I'd really appreciate it if this turned out to be my fix. Thanks.

I can't connect on VMWare Fusion and Windows 7. How did you fix your problem? Did you find drivers? Thanks.

wow. never had a problem on windows 7 or ubuntu getting the evo to be recognized. but, head to work, plug it in, and no go. install the sdk and update it, no go. i was baffled, because i've never had a problem before. but, this file did the trick! thanks!

Unfortunately for those of us who are behind a proxy and can't get at the SDK file, going through the stupid SDK to get the driver is very annoying.

[TUTORIAL] How to get ADB Bridge Interface working on Windows 8

I recently faced problem getting access to adb from windows 8 because of non compatible drivers... I searched a bit and found the drivers but they were followed by more problems such as unsigned drivers and ****.
So I made a simpler guide for everyone who was frustrated trying to get ADB working on Windows 8.
Files needed:
1. Drivers Mediafire | Dropbox
2. ADB Interface
Steps:
1. Download and Extract the drivers to any folder.
2. Now we need to disable signature checker. We can follow this guide
3. Now connect the phone. Make sure your android debugging is enabled.
4. Go to device manager. (Go to Start, start typing device manager, in that search click settings and select device manager)
5. Now find "Android Phone" with a yellow error sign in front. It will be expanded by default.
6. Right click on it and select update driver.
7. Select browse my computer.
8. Link to the folder where you extracted the drivers. Check the subfolder.
9. Click next. It'll display a warning. Select Install anyway.
10. Completed.
11. You may now download SDK and ADB.
Thanks to all the sites I linked and oops I forgot where I got the drivers from lol.
P.S. It is just tested on Wildfire S, It may work with other htc phones too and maybe with others too. Please Inform in thread if it works with your device.

thanks

What operating system on pc? You may need to unistall current drivers then reinstall the right one when connected, make sure debugging is turned on on the phone. You can also get drivers by installing pdanet, are you manually installing the drivers or letting windows do it? If you have windows can you dual boot a linux distro, no drivers needed then
Not to be rude but if you followed the guides to a t then all should be well

Chances are windows picks the wrong drivers no matter what you have downloaded. Not a pc right now so a walk through may not be accurate. But first download drivers from cyanogen wiki, xda wiki, or strawetals pdf guide. Just google search those and you'll find them. Know where they are downloaded to.
Now click start (windows circle) rightclick on computer, go to properties. Choose device manager and plug in phone while it is powered on, se what pops up as drivers. Right click on the driver and choose update, manual, browse to where you installed the drivers. Do the same with phone in bootloader mode.
Also make sure to have phone in debugging mode
There is also a windows program called usbdeview (or something like that) that will show you all drivers installed, here you can uninstall the wrong ones

>if u have htc sync installed + Android SDK .... go to cmd (run as admin) ,, make platform-tools as ur directory (inside SDK with cmd) & simply type * adb devices *
It will most probably show u ur phones serial number !!
after that follow cyanogen.wiki root method & install ICS Rom !!
Also , if ur already on a different custom ROM , HTC Sync willl NOT recognize ur device !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[Q] PC (HTC Sync) Won't install drivers

Hello,
I have a problem the my HTC One X and my (Windows 7 x64) Computer. It won't install the correct drivers to use ADB and to see it in Windows Explorer. I've tried everythingI can think of. I know there thousands of other threads like this, and I read many of them but none provide a solution for me :/. I'm sure my One X is not the problem, it's working fine, I have a laptop wich also runs Windows 7 x64 and it's all working fine on it. (It's a Lenovo Ideapad Z500, i7 version) What I've tried:
- 4 different USB Ports (I have tried 2 USB2 ports and 2 USB3 ports. No luck.
- Remove the device from system using Windows Device Manager -> Disconnect phone -> Install HTC Sync -> Reboot -> connect phone. Nothing happens, Windows reports no drivers can be found.
- Manually select drivers from the HTC Sync Installation folder. Windows tells me those aren't the correct drivers. (For me: C:\Program Files (x86)\HTC\HTC Driver\Driver Files\Win7_x64)
And yes, USB debugging is on, and I do accept HTC Sync Manager on my phone. I am running ARHD 31.0. My phone does connect OK in Fastboot mode, by the way. I can use Fastboot commands perfectly fine. (Flash boot/recovery image, clear cache etc etc)
I have no idea what to do to get it working, but maybe you guys do? Any tips/ideas?
Thanks in advance.

Had this problem last week. I solved it this way:
- Uninstalled HTC Sync + HTC Drivers
- Installed ADB Universal Drivers: http://drivers.softpedia.com/get/MOBILES/Clockworkmod/Clockworkmod-Universal-Android-ADB-Driver.shtml
- Rebooted PC
- Booted my HOX in bootloader
- went to fastboot
- connected usb cable between pc and hox
- went in recovery mod (latest cwm version)
- from there I was able to push adb commands from my pc
I basically did what is said on this page: http://news.softpedia.com/news/A-Clockworkmod-Universal-ADB-Driver-Is-Finally-Up-for-Grabs-343944.shtml
You can also use ADB over network if your phone boot properly and if your PC is on the same wifi network.

Thanks Alray for the tips but it doesn't install that driver either. Still a big ! in device manager named Android Phone. And I shouldn't need to push anything to the phone AFAIK, as I said it all works fine on the laptop, Including ADB!

All options I can find about downloading drivers from the internet are enabled. When I tell the PC to look online for drivers, it won't find anything.
EDIT:
Okay, I had the setup look thru the whole C drive looking for drivers, it reported it found one. But failed installing because files were missing..... !? That makes me think there's something corrupt in Windows/System32/Drivers or somewhere in those driver folders.

Try this Link I think it is helpfull, if didn't help I will but when I reach home.

Thanks for the link I was looking for something like that. But nothing works, I already had setup everything automatic updating and driver search thru windows update. It can't find any drivers.

Hey, I just wanted to chime in on this thread because I'm having precisely the same problem as Qubica.
I'm using Windows 7/64 and I've been using this laptop to manage/root/ADB several Android devices for as long as I've owned it.
I noticed last Friday that I could no longer mount my T-Mobile G2 either as a USB mass-storage device nor could I connect to it using ADB. This was the day after Windows Update installed a bunch of patches, and I had also installed the updated chipset drivers for my laptop a few days earlier.
I took a look at the device manager and this is what I saw:
(android_devmgmt.png)
Now, that's weird because I mount the storage card at least two times a month to move files around. So I did what seemed like the reasonable thing and Uninstalled the device altogether, and then installed the HTC Sync app to reinstall the drivers, as I had done originally. Unfortunately, the "Android Phone" non-detection of the device has persisted.
The installation logs from the HTC Sync app also indicates that the drivers were successfully installed, but the installer seems to quit about halfway through the process, so it's not at all clear that the installation logs are accurate.
Here's what the properties sheet of that device looks like:
(android_devmgmt_properties.png)
I've been following the advice I've read here and elsewhere: I've attempted to download several different versions of the HTC drivers from various locations and manually point Device Manager at the folders containing those drivers. I've extracted and executed the HTCDriver.exe installer separately from the HTC Sync installer. I've attempted to install generic ADB drivers from a number of locations, including Google and the Clockworkmod Universal ADB drivers.
Here's the result when I try to install the drivers (by pointing Windows at the correct location for the driver files) or if I allow Windows Update to search for the drivers:
(cant-find-android-driver.png)
So, this morning I tried the more drastic step of uninstalling all of the USB Root Hub devices and rebooting the laptop. When the computer came back, it did not automagically reload those generic drivers, but fortunately I was able to manually choose the generic (Standard USB Host Controller) -> USB Root Hub device from the list of options, and it worked---for getting the USB ports to function, but not the Android device.
I've also checked to make sure there were no software restriction policies in place in gpedit.msc that affected the installation of the drivers, and found none. I also poked around in the Registry in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\PnpLockdownFiles path and found no problems there with either permissions or settings.
I'm basically at my wit's end here; Windows is behaving like the driver installation is subject to a software restriction policy -- seemingly, actively preventing the driver from being installed -- but nothing shows up in the logs that would indicate that a policy is in place. The laptop can't mount the device, and I'm kind of stuck.
I guess I'll follow the thread for a while and see if anyone else has any suggestions. Thanks in advance to all that offer their help.

Hi, I've did everything you did execept for uninstalling the USB root hub and looking in the registry, I hope someone has a solution....

I prefer uninstalling the driver (Called unknown device, and it appears when I plug the device) from device manager, unplug your device then replug it again and wait for windows to get your driver.

If you can't solve the drivers problem, install linux then install adb and fastboot packages from the sftware marketplace. That should help.

perhaps uncheck mtp and select camera and turn off debugging ? boot into recovery while connected ? that installs a driver also. have you installed a "naked driver " ?

Need more info about your problem. what happens when you type adb devices?

If I'm not mistaken there were a few people that had the same issue and it turned out to be a bug when trying to use a USB 3.0 port on their computers. If you are using a USB 3.0 port for your cable you might wanna try plugging it into a USB 2.0. FYI I could be remembering completely wrong

I did everything but an engineering hboot with USB 2.0 port on an Intel x79 chipset motherboard on Windows 8.1.

I had this problem too but got around it. I had no problem getting the device detected in Fastboot mode, but ADB was a problem. What I did was download and begin installation of the latest HTC sync manager with the phone already connected. It seems the first thing it does is install updated drivers then asks if you want to continue with the installation. I didn't want to install sync manager, so I cancelled the install. However the drivers remained. After a reboot I checked Device manager and sure enough Android 1.0 device was there with working drivers.
Checked the device was recognised with the ADB command ADB DEVICES, but showed no device connected. I then unplugged the USB cable and plugged in to another USB 2.0 port and voila device gets deteced by ADB.
I also had to use this version of ADB http://www.mediafire.com/download/e5mieo2vxjd71ws/android-tools.zip and it had to be the original HTC USB cable and USB debugging enabled in Developer options.
Now for some reason I have to swap USB ports each time ADB doesn't detect the device and pretty much works each time.

I think it's usb3 issue , adb doesn't work on usb3 ports,
there was a subject on how to convert usb3 port into usb2 search the forums

USB 3.0 worked fine for me on 8.1. I used Sooner ADB drivers and manually picked them.

I have no issues on win 8.1 I use the Google USB drivers that are with the sdk. The first time, I do have to go into device manager and update the driver. When it asks do you want to locate the driver or pick it from a list select pick from a list. There should be an Android entry if you installed the USB driver. Select that and then select adb interface. You'll also have to do the same for fastboot mode the first time.

I couldn't find a working version of ADB for 8.1 however I installed HTC Sync from the virtual CD and that installed all the drivers. Uninstalled sync manager cos I don't use it and the drivers remain and work fine.

check your usb 3 controller. Is it intel 3.0 usb controller. if you see intel xtensible controller in device manager this could be the issue, it can break adb on all ports. here is a link to a fix for this usb problem i can confirm it works as i have had this issue myself. Hope this helps
