adb error: more than one device - android

Question

I have 2 Android devices connected via usb to my pc

now when i list devices i get this:

C:\Users\MBH>adb devices
List of devices attached
0123456789ABCDEF        device
0123456789ABCDEF        device

Both devices got the same serial number, or whatever this 0123456789ABCDEF means.

The problem: I am not able to do anything in this case, neither pushing or pulling files, nor forwarding tcp ports.

C:\Users\MBH>adb forward tcp:59900 tcp:59900
error: more than one device/emulator

C:\Users\MBH>adb -s 0123456789ABCDEF forward tcp:59900 tcp:59900
error: more than one device

The question: is there anyway to connect or select device in different way? like device model number or something?

i need them to be connected, i am working on both of them at the same time @Rohit5k2 — MBH, Feb 08 '16 at 12:17
it is usually `adb command -s`. Btw `forward` does not support `-s` (accordingly to the man page) — Blackbelt, Feb 08 '16 at 12:22

You can run every command of adb by selecting the device by deviceID. run command to get Device Id:

adb devices

you will get the list of all available devices something like this:

<device ID> device
emulator-5554 offline

the copy the device id run commad like this:

adb -s <device ID> <your command>

example:

adb -s <device ID> tcpip 5555

OR

adb -s <device ID> forward tcp:59900 tcp:59900

this will not get the error like "more than one device/emulator"

Thanks

I got it

C:\Users\MBH>adb devices -l
List of devices attached
0123456789ABCDEF       device product:ZEN model:ZEN device:ZEN
0123456789ABCDEF       device product:full_gs702c model:M757 device:gs702c

Then I could use the model number for shelling

C:\Users\MBH>adb -s model:M757 shell
shell@gs702c:/ $ ls

it works now
