[SOLVED] ADB on lastest CM9/CM10

After I flash the latest CM9 or CM10 builds, ADB no longer finds my phone.
I've checked my drivers and re-installed them numerous times and that doesn't help.
In CM9 I can mount my phone just fine, and I can explore the files with ease.
I have tried other Sense based ROMs and ADB will find my phone just fine. (The last one I tried was CleanROM4.5 and ADB found it right away)
I've tried the CM9 alpha4 build and ADB works perfectly.
ADB even works in recovery work.
I'm wondering who has it working and who doesn't.
Also, if you have it working, could I pick apart your brain to see what I'm doing differently?
Just try typing 'adb devices' and see if your phone shows up.
Finally solved this issue.
Here's how I did it in Windows 7 Profession 64bit. FYI, I have HTC Sync installed.
Plug your phone in to your pc.
Open up device manager (Right click computer -> Manage -> Device Manager)
Find your phone in the list.
Mine was initially under 'Other Devices' labeled as 'One'
Right click -> Update Driver Software...
Select 'Browse my computer for driver software'
Select 'Let me pick from a list of device drivers on my computer'
Make sure to uncheck 'Show compatible hardware'
Select 'Android Phone' then 'Next'
Select 'Google, Inc' on the left pane and 'Android ADB Interface' on the right pane. Hit Next
Hit 'OK' if there was a warning.
To test if ADB is working, launch a CMD prompt and type 'adb devices'
You should now see you phone in the list!!
p.s. mounting your sdcard should also work.

I'm in the same boat with ya. I've been trying to figure this out on my phone but have come across no solution. Nobody seems to like using adb here but I find it quite useful.. anyway I found that just using adb over WiFi is sufficing for now. Hope it gets fixed tho.

That's good to know it works over WiFi. I haven't tried that myself, mainly because I don't know how.
Is it easy to set up WiFi ADB?
I need it for App development so it would be nice to get some form of it working
(At least I'm not the only one having issues)

Yup really easy. Just select the option right under enabling adb in the settings app that enables adb over WiFi. Then in the cmd prompt type "adb connect x.x.x.x:5555" where x.x.x.x is the ip address it gives you in the settings. Then you should be connected. To double check just check adb devices and it should show up.

Mine comes up as HTC MTP Device and when I go into device manager and try to manually install it still fails. It doesn't come up as "One" and it won't let me choose "Google, Inc." As soon as I plug the device into the computer it starts to install the drivers and that's when it switches from "One" to "HTC MTP Device". Is there a way to make it so Windows 7 doesn't automatically try to install drivers for a device when you plug it in?

Oh and p.s. Make sure to uncheck 'Show compatible hardware'

This worked perfectly! Thanks for this.

Hmm I have not heard of that issue before. That is interesting indeed. Did it used to work before on stock/other ROMs?

Well, I TRIED to follow the directions above, but I don't have the "Show compatible hardware" check box, and googling for the problem only turns up solutions to other devices that require the unchecking of that box...none, where the box IS the problem...

Unfortunately, no. I've resorted to using the terminal emulator on the phone when I REALLY need the console, and I can still mount the USB storage just fine, so it's not ideal, but I've been making do.

Solved for LG OB

Nope, still nothing. My Razr HD comes up fine, but not the Nexus 5. Think it's a conflict in drivers?

definitely...the only time i ever had Nexus driver issues was when i changed from HTC to Nexus
the best i can offer is how i fixed it...get a copy of Wug's Nexus Root Toolkit and follow his instructions from deleting all other drivers and installing new ones...he offers (i think) 4 different options and you just work your way through them until one stick (the RAW drivers always work for me)
and note that the Toolkit doesn't work on 4.4 yet, so only use it to clear and update drivers

Thank you n7of9 the link you provided worked for me.

Another solution...
Plug the phone into your computer. Go to "Device Manager" and find the Nexus <x> device where-ever it's listed (may not be called "Nexus...", though on my machine with the real drivers it was).
Right click, choose "update driver software"
Select "browse my computer"
Select "let me pick..."
Choose the option. "usb composite device"
Apply and close all windows.
Disconnect and reconnect the phone to the computer.
The phone will now allow you to move files to it properly. Something weird with proper phone drivers. I believe you need to reverse this if you need to use ADB again in the future.

This worked and also fixed another popular issue
Not only does this fix the MTP connection issue to move folders to root folder. But it also now allows me to see the preview thumbnails of my media! This was a huge problem on my other phones and many many people including me were never able to fix that. All the ideas to get around or create USB Mass Storage instead of MTP after 4.1 were fails.

Worked perfect, thanks

what worked for me
In windows 8.1
I plugged in my nexus and browsed to device manager in control panel
I uninstalled the device (and deleted the driver)
I unplugged the nexus 5
I plugged it back in
Windows recognized it as a proper MTP device
I think the problem was something to do with windows recognizing it as an ADB device (I had installed the toolkit before etc)
This fixed it for me

Hi,
I did all the steps mentioned, and ran the driver test - everything works fine, success.
However, I still cant see my device in "This PC"...
What is even more weird, that it only disappeared couple of days ago, and I didnt do anything to my computer at all....
Any other way to get devices to show? (Nexus 10 or Nexus 4 stopped showing too).....
Maybe problem is that it is being shows as ACER ADB Interface? But i cant change that to MTP anyway..

[Solved] ADB device not found

Hi, I'm trying to go back to stock rom following this guide but I can't get adb to recognize my phone (even if I've already used adb in this pc to unlock the bootloader and flash the custom recovery). I'm on Liquid Smooth ROM and my pc has Windows 8.1.
I tried uninstalling motorola drivers and reinstalling again and uninstalling and letting windows install the drivers automatically but no luck either way (and USB debugging is activated in the phone).
When I access to the device manager in the pc it shows a warning sign on Motorola ADB Interface saying the controllers for that device are not installed, that the manufacturer is unknown and that there aren't compatible controllers for the device (I'm translating what the pic says for those who don't understand spanish xD). I tried to uninstall that Motorola ADB interface thing but it remains there.
What can I do?
SOLUTION: See last post.

You'll need to manually install the driver for the unknown devices. Point to your motorola driver folder.

Are you on CM11?
I had the same problem, tried Motorola USB Driver, Universal ADB driver, Google USB driver and also editing the USB.inf to match the hardwareID.. none of that worked until I set the USB computer connection to Camera (PTP)
Good luck!

EDIT: I've found the solution, I noticed I had two Motorola ADB Interface controllers, one in "Android Devices" and the other in unknown controllers. I went to the unknown one and imported the same certificate the upper one had and now it works (though I have two Motorola ADB Interface in android devices).

In fastboot mode, I made the USB work by using Koush's Universal ADB driver.
But if you are using Windows 8 or 8.1, you'll need to turn off the forced signature verification before you can install the drivers, since they are not signed.
Well... glad you got it..

Go to device manager, you should see a device called "Android Device" (IIRC). Right click to update device drivers, select device driver, manually search for one but then pick choose from a list. You should be able to see the right driver that is normally used.

Nexus 5 showing up as ACER ADB Interface Windows 8.1

Hi guys, I recently installed windows 8.1 and now my N5 shows up in device manager as ACER ADB Interface and I can't acces MTP , I didn't had this problem with windows 7 , it worked perfectly back than ( i have unlocked and rooted my N5 with windows 7 without any issues ) . What can I do to make it work with windows 8.1 ?

I had the same, you have to go into Device Manager and roll back the driver to the Google one. Proper PITA

I can't do it, the roll back option is grayed out

I have managed to make it work, nevermind .

I rolled the driver back, but it keeps updating to it. I've uninstalled and deleted the driver, yet it keeps reinstalling it. Somehow, my MTP connection started working again. Not sure how though. If I knew which KB update it was, I'd uninstall it from there.

The other option is to manually change the driver in Device Manager from the ACER one to the Google one. I think it's happened as M$ have the ACER driver digitally signed whereas the Google one isn't so it'll always choose the signed driver...

I'm not sure how to do that, because, of course, if you try to update it, it will say that the Acer one installed is already the best driver. And after uninstalling it, upon plugging it back in, it updates to the Acer driver automatically again.

You have to manually check and select 'choose from a list' and you'll see the MTP option as well as the Acer one. Select the MTP one and you're good to go

Hmmm, I've only ever used the Google drivers from the SDK until this stupid ACER one appeared. Managed to get back to it now so it's all good. Perhaps download the Google driver and then point to it?

This worked for me
Hi guys, I had the same problem. My phone was configured as MTP but when i connected to Win 7 it would appears in the Device Manager list as "ADB", this wouldn't allow me to transfer files so what worked for me was:
1- Connect your Mobile to the PC and it appears as ADB Driver (In the device manager screen), rignt click on ADB and select Browse my computer for driver software.
2- Choose let me pick a from list of devices on my computer and choose the option MTP instead of ADB.
3- Did that and problem solve, hope this helps for you !!

Delete this Acer ADB driver when you uninstall it
I have the same issue. Here is what I did and that resolved the issue. Go to "Device Manager" to uninstall the Acer driver. The uninstall window pops up asking you if you want to uninstall it. There is a check box that says "Delete the driver." Make sure you check that off and then go ahead and uninstall it. Once that's done, plug your Nexus 5 back in. The correct MTP driver will now be installed and your computer will recognize the phone normally. Hope this helps.

Experiencing the same on Windows 7...have tried everything suggested
Really hoping someone can help because I've just about had it with this. I'm running Windows 7 Home Premium 64-bit. I have a brand new Nexus 5 16GB. As others have indicated, when I plug my phone into my computer with debugging enabled, it creates an "Android Composite ADB Interface" device listed under "ACER Device" in Device Manager. See attachment.
I have tried every permutation of the 'uninstall driver, manually install Google USB driver' solution, to no avail. The best way I can describe what I'm seeing is that Windows is forcibly categorizing the device as an 'ACER Device' even though the driver files themselves are telling it otherwise.
If debugging is DISABLED, and EITHER MTP or PTP is ENABLED, everything is just fine - the default Windows drivers for those devices kick in, and no 'ACER Device' category is created.
If debugging is ENABLED, and MTP and PTP are DISABLED, when I tell Windows to use the Google USB driver, it says that the device could not be installed.
If debugging is ENABLED, and MTP is ENABLED, the 'ACER Device' issue rears its ugly head even when I tell Windows to use the Google USB driver.
I've already disabled Windows automatically fetching a driver online, so that's not to blame.
If this is the result of a Windows Update, does anyone know the number of the update so I might try uninstalling it? I can't seem to find it despite searching.
Hoping someone out there can help. Thanks!

[Solved] USB suddenly stopped working

I have a Nexus 5 that I have had about a month now and I had the USB on it working before about a week ago. I plugged it in today and neither my desktop or laptop could recognize it anymore. Both computers are running Windows 8.1.1 and the issues seems to be new as I can neither get USB storage or ADB to find it. The closest I can get it to working is to switch the USB mode to PTP and it reads that but I don't want to pull photos off. When I have it in MTP, it makes the sound of it plugging in and my phone shows it is plugged into a computer but Explorer shows nothing and it says it is working normally in device manager. I've tried everything from enabling and disabling debugging, restarted both my phone and computer tried reinstalling the drivers (both by the computer automatically finding them and manually installing them) but nothing seems to work. Is it possible that Windows Update could of broke the drivers since my computer installed updates yesterday? I also have Linux on my laptop and it appears to read fine with Linux.

That's the exact issue. If you check in Device Manager you'll see it listed as 'ACER ADB Device' (or something like that). You have right-click on it, select update driver, manually check and go through the list option and choose the MTP driver and it'll work again (and with USB Debugging enabled if you don't usually have it on like me)
I theorise that it's happened cause the Acer driver is digitally signed and the Google ones aren't but I could be wrong. Either way, it's a PITA

OK thanks. I'll give it a try because it was showing up as ACER ADB Device under device manager
EDIT: I updated the drivers and used the USB composit drivers instead and it got MTP working again. When I set it to USB composit, it installed Google's ADB drivers and the Nexus 5's USB drivers so everything is working again. Thanks for your help

I can´t manually update driver because of this:

when i update the acer adb it says the driver is up to date and everything is all same. what to do?

Thanks! Thought I was going to go crazy. Worked for me...

i set the driver to MTP as mentioned above and the phone started to show up on the explorer but now i couldnt copy any files from my laptop to the
phone. It displays like that and if clicked yes then the copy wouldnt happen.what is the problem.

Uninstall driver, plug in device, tell windows to not auto install driver (or disconnect from internet), click to update or install driver, point to folder with drivers, install, all is done.

That msg comes when you're in PTP mode I think...Only certain formats are supported.
Check under storage, expansion menu and make sure you are set to the first option...not PTP.
Above guy mentioned to have phone in USB debugging mode when setting up drivers.

If the device is showing then you need to point to the drivers for it (download them from google). I reinstalled windows a few days ago and had the acer issue (device first shows up in device manager as nexus 5 then switches to acer), windows wants it to be an acer device. Stop windows and then install the correct drivers,
For me I had to click the auto install in windows tray and tell it to stop. After a few times it worked.

No I'm connecting in MTP mode. Ahh its gettn irritating.
