Ubuntu adb devices can't find anything to install the driver

In the Android platform to do development, ADB always need to use, and, because Linux does not have windows such as a fool, some things still need to set their own, otherwise it will not be connected.

Google also has a description of these content, can refer to http://developer.android.com/tools/device.html

This problem has not been paid attention to, my Samsung GT5700 mobile phone and Huawei T9200 mobile phone connection has been very smooth, ADB devices every time can see the device, but to Spreadtrum's 6820 platform found dead or alive find equipment, this depressed, spent some time to search data verification, Finally succeeded, the following summarizes the ADB device driver installation experience, I hope that the Ubuntu system debugging Android device students have a help.

1. Make sure the device is connected properly

First you need to get root permission, this is nothing to say. Then use the LSUSB command to list all USB devices as shown in:

Here can be relatively clear to see there is a device, ID number is 1782:5D04, if your system has a lot of USB device connection you can not see clearly, Plug and play the device ID number comparison, make sure to find this ID.

The front of this ID is actually the vendor number, followed by the product number. The vendor number is unique, such as HTC is 0x0bb4,samsung is 0x04e8,qualcomm is 0x05c6, Huawei is 0x12d1. The 0x1782 we see here is the company number of Spreadtrum.

2. Create a configuration file under/etc/udev/rules.d/

This configuration file will be queried when the device is connected, such as 51-android.rules.

Edit the contents as follows:

subsystem== "USB", ATTR (idvendor) = = "1782", mode= "0666", group= "Plugdev"

Here's a few options to explain,

subsystem is the logo which is a USB device,

ATTR (Idvendor) R This is a description of the manufacturer's ID number,

Mode describes access rights.

Group is described as Plug and Play, but it is not very useful here, can not write

In fact, you should also write an owner, to specify which user has permission to operate, if not write is root (not all users can access), this need to note, sometimes some students are stuck here. Because I've been working with root permissions, I've omitted this.

Also, there are times when we see sysfs{"High Tech computer Corp." Such an item, this parameter is also the device manufacturer's meaning, it seems that the previous official was so written, originally because HTC helped Google phone, so the first use case was written "High Tech Computer Corp.", but now the official example has been changed to attr ( Idvendor).

3. Set permissions for this file

chmod a+r/etc/udev/rules.d/51-android.rules

4. Restart Udev

/etc/init.d/udev restart

5. Add Adb_usb.ini File

In the ~/.android directory to add a Adb_usb.ini file, where the path is actually the root of each user, if you need to switch users, remember that each user needs to add this stuff.

Adb_usb.ini file to write the vendor ID number, and the difference is that it needs to write 0x prefix, for example, my Spreadtrum phone is to write 0x1782

Search online A lot of information, this step some of the information did not mention, estimated that they did not use this step to succeed, but I am not successful, until the addition of this document, card a lot of time.

6. Restart ADB

ADB kill-server

ADB start-server

ADB devices

At this point you should be able to see the device, the following will be normal use of ADB
