procedure.

4. If the installation program instructs you to restart you PC, please do so with out fail.

Above installation procedure should get you started to use your new driver. Please follow the following instructions for how to use the Samsung USB Driver 4.34 with the SCH-U620.


How to use Samsung USB Driver 4. 3 4 with SCH-U620

1. After you have successfully completed the Samsung USB Driver 4.34 driver installation procedure, now you can connect your USB cable from PC to handset directly or via USB hub which you may have.

2. For the first time when you connect your handset to the PC, driver initialization may take couple seconds. Please be patient and allow the PC to finish the driver initialization process completely. During the initialization you may see some notification displayed on the screen depending on the Operating System that you use.

3. After successful driver initialization, to see which COM ports are assigned to which Service, check in the Device Manager on your computer, you should see window as shown in the Picture 1. To understand more about these COM ports please read FAQS section which may answer your questions.

4. To simplify the explanation, let me assume that you have single SCH-U620 handset connected to your system through USB cable. As soon as you connect, you will see two COM ports assigned as shown in the Picture 1.For example:

Samsung CDMA Modem #9 is assigned to COM19 for Data Services (Laptop Data Call)

Samsung CDMA Modem Diagnostic Serial Port (WDM) is assigned to COM20 for Diagnostic Services (CAIT, QXDM, PST tools etc.)

5. Now that you have two separate COM ports assigned to both of these services, it allows you to make Laptop data call on COM19 and at the same time you run CAIT application on COM20.

6. Remember, you CAN NOT use COM19 to run Diagnostics tools (CAIT, QXDM, PST tools) similarly you CAN NOT use COM20 to make Laptop top data call. They can only run services which are dedicated to them.

FAQS

1. How SCH-U620 is different compared to previous models like SCH-A890 etc?

U620 is a composite device, which means USB exposes multiple channels (COM ports) to PC. U620 currently supports two USB channels, Primary channel is dedicated for Data Services (Laptop Call) and Secondary channel is used for Diagnostics Services (CAIT, QXDM, PST tools etc.). Both of these applications can be run parallel at the same time.

2. Can I see the Data call logs in QXDM while I have active Laptop Data Call connection with the same handset?

Yes, when you connect U620 handset using USB cable, you will see two COM ports as shown in the picture 1.

Samsung CDMA Modem – This port is dedicated to Laptop Data Call servicesSAMSUNG CDMA Modem Diagnostic Serial Port (WDM) – This port is used for Diagnostics services. Using this port you can run Diagnostics applications like CAIT, QXDM, PST tools etc.

So having two separate ports enables you to run QXDM on the DIAG port while you are having Laptop data connection active with Data Service Port.


Picture: 1

3. If I have three U620 devices connected through a USB hub on my PC, do I see 3 Data Services COM ports and 3 DIAG COM ports?

That’s right, like as shown in the Picture 2 you will see 3 Data Services COM ports and 3 DIAG COM ports, but one thing you have to keep in mind is when you connect multiple handsets, you will have to manually remember which COM ports are assigned to which devices, otherwise there is no way to identify which is what.


Picture: 2

4. Can I use Diagnostic COM port for Laptop Data Call?

NO!! YOU CAN NOT!! Diagnostic COM port is only dedicated for diagnostic tools and it can not run any other service. Similarly you can not run Diagnostic tools on Data Service COM port.

5. Is Samsung USB driver backward compatible?Yes it is, if you connect SCH-U620, which is not a composite device so you will only see Samsung CDMA Modem device in the Device Manager.
