I’ve got a cheap android tablet and I need to use it to test

  • 0

I’ve got a cheap android tablet and I need to use it to test apps on it. I am using Ubuntu so I first have to add the device to udev list.

I connected the tablet, but adb does not see it

$ adb devices
List of devices attached 

$

The I tried using lsusb, but the device is not identified to the Ubuntu (USB debugging is checked! in tablet’s properties)

$ lsusb 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 002: ID 046d:0928 Logitech, Inc. QuickCam Express
Bus 005 Device 002: ID 046d:c517 Logitech, Inc. LX710 Cordless Desktop Laser
Bus 001 Device 004: ID 2207:0000

If I attach my mobile phone, I see that it is connected via the last channel. So, I assumed that this tablet is identified as ID 2207:0000, thus making ID Vendor “2207”. I edited udev file 51-android.rules to look like this 

SUBSYSTEM=="usb", ATTR{idVendor}=="2207", MODE="0666", GROUP="plugdev"

Restarted the comp, reattached USB cable to the tablet, the the tablet was not recognized again.

Any advise of what should I do? How to make this tablet be visible to the adb?

EDIT

Does this vendor id looks odd to you: 2207:0000? Especially those four zeroes?

    For all those having a tablet with ID 2207, these 2 links made it be visible.

    First one is this one (http://clamel.netai.net/smartpad850i/enable_adb).

    It will help you set such device up. If after this setup the tablet appears as ???????, then use the other link to make it visible.

    The other link is here (http://ptspts.blogspot.com/2011/10/how-to-fix-adb-no-permissions-error-on.html).

    If after system restart you lose the settings, then either repeat the same steps or simply restart udev service.
