Android Device has no Serial Number

I have been trying to get adb to recognize my Huawei 8150 Ideos Android Device, flashed with CyanogenMod 7.2.0, but currently, it only shows

$> ./adb devices
List of devices attached 
????????????    device

Which is an issue because it prevents me from using the automated deployment mechanisms of IDEs like android-studio, which I am currently using.

It should be noted, that I can indeed deploy .apks to the device directly from the command line using

$> ./adb install -r /path/to/apk/app-debug.apk 
1577 KB/s (1166600 bytes in 0.722s)
    pkg: /data/local/tmp/app-debug.apk
Success

I have found out, that adb takes the serial number information from the iSerial field from the devices USB interface. Here is the relevant section of lsusb:

$> sudo lsusb -v
[ ... ]
Bus 003 Device 020: ID 12d1:1038 Huawei Technologies Co., Ltd. Ideos (debug mode)
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.00
  bDeviceClass            0 
  bDeviceSubClass         0 
  bDeviceProtocol         0 
  bMaxPacketSize0        64
  idVendor           0x12d1 Huawei Technologies Co., Ltd.
  idProduct          0x1038 Ideos (debug mode)
  bcdDevice            2.26
  iManufacturer           1 Huawei Incorporated
  iProduct                2 Ideos
  iSerial                 0
  bNumConfigurations      1
  Configuration Descriptor:
    [ ... ]

As you can see, the iSerial field is 0, so it seems to me, that my device does not even have a Serial Number to be read by adb.

I am not sure how to debug this issue,or if it is even fixable, and I would appreciate any help.

I have the same problem with my Huawei G600 phone. Despite being unable to return a valid ID/serial number when my phone's connected via USB, adb seems to communicate with the device just fine. Still, the invalid ID reported by adb trips up AndroidStudio.

Here's a workaround, if you don't mind doing it wirelessly.

Start with the device plugged in via USB, then:

$ adb usb
restarting in USB mode

$ adb devices
List of devices attached
????????????    device

$ adb tcpip 5555
restarting in TCP mode port: 5555

Now find the phone's IP address via Settings → About → Status → IP address.

$ adb connect YOUR_IP_ADDRESS
connected to YOUR_IP_ADDRESS:5555

$ adb devices
List of devices attached 
????????????    device
YOUR_IP_ADDRESS:5555 device

Now you should be able to access your device from AndroidStudio, etc.

When finished, adb disconnect YOUR_IP_ADDRESS
