Acer Iconia A500 not in adb devices

问题:

Just picked up an Iconia A500 (yay $100 off coupon) and started messing with it playing games, etc.

I decided it was finally time to work, fired up adb and launched eclipse to test an app and I discovered it wasn't in my devices list. I've tried installing the acer drivers. It puts a folder in my Program Files directory...but I don't see what I'm supposed to do there. There's "EUUDriverInstaller" but when I click on it nothing (seems to) happens.

When I plug the device in it uses some generic Microsoft driver to show the device contents but composite adb doesn't show up at all like it does for my Droid.

I've reboot several times on both device and laptop. I've uninstalled / reinstalled the application that made that driver directory. I opened an application in the driver directory under the x64 folder and it opened up the windows driver installer and installed some drivers...but still no composite adb when I plug it in. It is on usb debugging and I've toggled it on and off.

It's running 3.1 stock I'm on x64 Windows 7

Both command prompt adb devices is empty under "List of devices attached" and Eclipse devices is empty. My sdk is fully updated.

I have solved the same problem by this way: connect your device, start Device Manager, find missing device driver, select update driver and browse the folder with acer drivers.

Yet another set of symptoms, and another answer....

A500 using 3.2 roms (I have other 4.x devices, so I'm saving this one). Using Windows 8. Downloaded and installed the Acer 1.06 drivers. Have previously isntalled Google ADB drivers for the Nexus 7 from android-sdk\extras\google\usb_driver\amd64 (or i386 if that's appropriate), but that may not be required.

Plug in the A500, and launch device manager. The Acer Iconia Tab A500 device shows up in "Other Devices" folder but with no drivers installed. Click on the device, click on "Update Driver". Select "Browse my Computer". Click "Let me pick from a list of device drivers on my computer". From that list, select "Android Device". Select "Google" as manufacturer, and select "Android ADB Interface" as the Model. CLick "next". Click "Yes really, really do it please". Done.

Edit:

On windows 8.1, the behavior is different again. The device will show up in the "Android Device" folder. Right click on that, and proceed as described above to select and isntall the "Android ADB Interface" driver. I'm having to do this with all my devices. Windows 8.1 seems to istall everything BUT the ADB driver, which you need to forcibly install using this procedure.

Acer Iconia A100 won't allow USB debugging on Win7 - Android 3.2.1 - No doubt a similar problem to the A500 described above.

USB debugging enabled, connected to Win7 x64 - "adb devices" would not find the tablet, nor would DDMS, which I need for screenshots (don't want to root the tablet).

Folks here are right: Win 7 is single-minded about using its own driver for this tablet, and the Acer installer simply drops the files onto the drive. In fact, it drops them onto the drive, then seeing that the Windows driver is already in place, happily deletes the Win7 drivers it has copied out of the installer. I spent an hour in Device Manager trying to con Win7 into using the Acer drivers, but it kept telling me they were not compatible.

MY SOLUTION: 1. Run Device Manager with tablet attached. 2. Update driver software. 3. Browse my computer for driver software 4. Let me pick from a list... 5. Select USB Composite Device.

Win7 insists that the A100 is a MTP USB device, whatever that means.

Finally, I told Win7 to pound sand and selected "USB Composite Device". Immediately "adb devices" found it.

Ahhhh. I can DDMS again.

I had this same problem on Windows 8. The installer did not work for me, and since the actual drivers installer comes packed in an EXE so you can't install manually. Here's how to fix:

1. Run the EXE provided by Acer.
2. Now locate the ACER ICONA 3G DRIVER INSTALL .msi file. I couldn't find where the installer was copying the msi manually, so I used the sysinternals utility handle.exe to tell me which files the installer had open.

handle -p "ICONIA TAB USB DRIVER SETUP.exe"

1. Once you've located the installer, copy it to a temp folder and extract the contents. I used 7-zip for the task.
2. Use the device manager to manually locate and install the drivers.

回答6:

Unfortunately, plug again and again (and again?) didn't help me.. neither did switching usb ports.. It really took me 3 days search quite a lot of post threads to solve the problem. Just come back to share with those stopped by the same puzzle :)

Reference: Connect to Android with ADB over TCP

The above instruction requires a PC which can ADB to your tablet over usb. Better work-around is root your device firstly, and then download a adbWireless, so you can switch your tablet to ADB TCP mode even without USB connection at all.

HTH!

回答7:

Just change USB ports, worked for me :-)

回答8:

I could be wrong, but you may have to root the Iconia to get ADB. I will be trying this later tonight and I will check back.

EDIt Figured it out, you need the ACER USB driver from their website (http://support.acer.com/us/en/product/default.aspx?tab=1&modelId=3851). Installing that got it working for me.

回答9:

None of the other answers worked for me, but it pointed me in the right direction. I had to hack the drivers similar to http://www.davinciunltd.com/2011/10/hacking-the-adb-usb-driver-for-acer-a500/ and then manually point the drivers to the hacked inf.

My device hardware ID and the inf file were a bit different from the ones in the link but the general idea is there. Note that the x86 / x64 folders for the acer driver correspond to your operating system version, not the version of android sdk on your system. I'm on Windows 7 64-bit so I used the one under C:\Program Files (x86)\Acer Inc\ACER ICONIA TAB\Win7\ADB\x64\android_usb.inf

For Windows 7: In my case I just go to Device Manager -> Portable Devices -> Acer ICONIA TAB A100 right click on mouse and Update Driver, after that Compound Device will be installed. And Android USB Devices appear.

Good luck!

This is how i solved the issue on windows 7

1- I open device manager and right click on 'B1-A71' under portable devices and click update driver software.

2- Click on browse my computer for driver software.

3- Click let me pick from a list of device driver from my computer.

4- It will install the usb driver automatically but to make it detect with andoid ecplics you need to install the driver from http://www.acer.co.in/ac/en/IN/content/drivers

(keep the device connected for all steps)

Same problem with Acer Iconia A510 on Vista.
Resolved as follows:
Running the driver installer unpacks all the files, then deletes them without installing

• Download driver file from Acer & run
• Check C:\Program Files\Acer Inc\Acer Iconia Tab Driver install at each point before clicking 'Next' or 'ok'
• When the driver files appear, copy the whole lot somewhere else
• Continue the process to the end
• The files will have disappeared; copy your copy back to the Acer directory
• Plug in the device, and continue the windows driver lookup process till it asks if you want to tell it where to look
• Select the directory with the files - windows installs them ok
