adb got two same serial numbers when connected to two smart phones

Question

I have two smart phones (ZTEV788d, system Android 2.3.6) connected to a computer (Ubuntu 11.10) at the same time, using co

Answer 1

Today I found an easy solution for this issue.

adb devices -l

You'll get list of devices with their qualifiers

List of devices attached
P753A12D device usb:26200000 transport_id:1
P753A12D device usb:24400000 transport_id:2

Then you can use qualifiers instead of serial numbers like this

adb -s usb:26200000 install xxx.apk

or with transport_id and -t

adb -t 1 install xxx.apk
