- If customers take the computer with Windows operating system to do the test, please get
the Huawei module Windows driver from technical support engineers.
- If customers take the computer with Linux or Android operating system to do the test,
please refer to Guide to Kernel Driver Integration in Linux for Huawei Modules to review
and modify the kernel code, so that the module driver can be loaded in normal way.
- This section takes MU509-b module as an example for reference.
2.3.1 Finding out VID and PID on Windows Operating System
The detailed steps are shown as following.
Step 1 Connect the module and the computer with Windows operating system by the USB
cable.
Step 2 Enter Start > Computer. Right click Computer and select Manage. Then Computer
Management window will be displayed. Please refer to the red marks in the image
below. Select Device Manage and expand Ports (COM & LPT) node to find out
Huawei module serial ports.
The ports in the figure are provided only for your reference. The actual module may be
different.
Step 3 Select anyone of the Huawei module USB serial ports. Right click it and select
Properties to open the port’s properties menu. This section takes Mobile Connect –
3G Application Interface (COM27) port as an example.

Step 1 Connect the module and the computer with Linux or Android operating system by the
USB cable.
Step 2 Open the command window and run the command lsusb. Then all the devices
mounted on the USB bus will be listed. Customers can find out the Huawei module's
VID (VID=0x12D1) and PID value
Step 3 Run the command lsusb –vd 12D1:PID (this PID should be the value got from the
Step 2 ), and then all the descriptors information of 12D1:PID will be listed.

3.7.4 On Other Operating Systems
Customers need to select the correct module USB interface configuration referring to
that configuration model supported by the host system. If the host system does not
select one configuration of ME909s series module actively, then the ME909s series
module will enumerate the serials ports as that on Windows XP/7, which means the
bConfigurationValue=1.
