Tablet not appearing in ADB_问答_开发者_运维开发者技术经验分享

I've just got a Lenovo Thinkpad Slate Tablet running Android and can't for the life of me get ADB to recognise it in either Win7 or Kubuntu.

USB debugging is on in the tablet settings and when I connect the tablet to the computer the "USB Debugging Connected" message appears - so all good from the tablet side of things. The computer side of things isn't so great.

Kubuntu (my main dev machine)

I've开发者_运维技巧 added the vendor id to the /etc/udev/rules.d/51-android.rules file (as directed here) - have tried each of the below, one at a time, with no success.

SUBSYSTEM=="usb", SYSFS{idVendor}=="17ef", MODE="0666"

SUBSYSTEM=="usb", ATTR{idVendor}=="17EF", MODE="0666", GROUP="plugdev"

SUBSYSTEM=="usb", ATTR{idVendor}=="17EF", MODE="0666"

SUBSYSTEM=="usb", ATTR{idVendor}=="17ef", MODE="0666"

For reference I have SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0666", GROUP="plugdev" for my Nexus S and it works fine.

lsusb prints out:

root@ubuntu:/etc/udev/rules.d# lsusb
...
Bus 002 Device 008: ID 17ef:741b Lenovo 
...

Windows

Have followed these instructions and still not getting any response from adb devices.

I've restarted both machines and the tablet several times to no avail. Can anyone help?

Creating the file ~/.android/adb_usb.ini and adding the vendor id (0x17ef) and restarting adb seems to have fixed the issue in both Windows and Kubuntu.

I had a problem with the Lenovo's page. My thinkpad was listed under portable devices and following the directions got me "Unable to find drive for your device". I was able to remedy by search internet for updates (which updated to a USB driver and this moved my Thinkpad to the other device's category in the Device Manager). I then was able to use the instructions as listed on the web page.

I had tried several ways, especially posts from Lenovo forum but no luck. Finally, I have found my way.

Enabling USB debugging
Download the driver from Lenovo, unzip and update your device driver. I think some people would be success as @Pooks answer then you can stop. Otherwise, continue as below.
If latest driver does not help or Windows could not install driver for your device, let check its Hardware Ids. Mine is USB\VID_17EF&PID_741B
Open the android_winusb.inf, find these settings

[Google.NTamd64] ;Lenovo Think Tablet %SingleAdbInterface% = USB_Install, USB\VID_17EF&PID_741B %CompositeAdbInterface% = USB_Install, USB\VID_17EF&PID_741B&MI_01 %CompositeAdbInterface% = USB_Install, USB\VID_17EF&PID_741C&MI_01 %CompositeAdbInterface% = USB_Install, USB\VID_17EF&PID_741D&MI_02 %CompositeAdbInterface% = USB_Install, USB\VID_17EF&PID_741E&MI_02

Mine is USB\VID_17EF&PID_741B, so I just remove the rest. Now it looks like

[Google.NTamd64]
;Lenovo Think Tablet
%SingleAdbInterface% = USB_Install, USB\VID_17EF&PID_741B
%CompositeAdbInterface% = USB_Install, USB\VID_17EF&PID_741B&MI_01

For now, just update your driver again. Windows should install your device properly. You can check the device connection by ADB devices, mine is

C:\Android\android-sdk\platform-tools>adb devices
List of devices attached 
MP0398W device

Download and install the drivers using the Lenovo Smart Assistance program from Lenovo's page:

Just download, install and run the program.

Tablet not appearing in ADB

Please see this question. One of the things to make sure of is that you are not using a cheap $2 knock-off USB cable. I did this once and couldn't figure out WHY my computer would not recognize my phone. Replacing the cable fixed everything.

I got mine to work by going to Lenovo's ADB Interface Driver - ThinkPad Tablet download page and following the installation instructions there. Worked like a charm!

There might be a lot of issue, but after you do the basic steps like enabling USB debugging and all, if still it does not work follow below steps which helped me for ubuntu (all tablets):

open terminal, type lsusb, it will show all the devices connected. Find out the vendor id of your device.(Try disconnecting and run command lsusb and the reconnect and try lsusb command, you will find out which is your device. so against your device you will find something like 0574:4798 XYZ COrp.). So 574 is your vendor id.

eg: Bus 002 Device 003: ID 0a5c:e784 Broadcom Corp. Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 005: ID 0cf3:3005 Atheros Communications, Inc. AR3011 Bluetooth Bus 001 Device 003: ID 04f2:b249 Chicony Electronics Co., Ltd Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

a5c is my vendor id

type cd .android in terminal
open adb_usb.ini
add 0xa5c in new line.
save and close.
kill adb-server or sudo kill adb-server
start adb-server or start adb-server
sudo killall adb
connect your device in debug mode.
Voila you are good to go my friend.

For Ubuntu, I just added SUBSYSTEM=="usb", ATTR{idVendor}=="17ef", MODE="0666", GROUP="plugdev" to my /etc/udev/rules.d/51-android.rules file. Restarted adb, and then it worked!
