Changing COM Port of USB2SER Driver

[kamaljoshi]

Hi,

I have the following hardware and the driver installed on my computer.

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?

code=USB2SER&lang_cd=

However, I can not change the COM port of the USB.

Is it possible to change this COM port somehow to the number I like ?

I have install the drive in ubuntu16.04 with USB2SER_Driver_Linux, but failed. Pls help .

Hello,

I’m afraid that the option for changing the COM port number is not supported by the USB2SER driver that includes flow control support; however, there is a workaround that consists in temporally changing the used driver for the standard CDC driver (without flow control) using the INF file purposed on Appendix C of USB2SER Datasheet (attached). The procedure is the following:

1. Go to “Device Manager” and expand “Ports (COM & LPT)” menu.
2. Right click on “Freescale CDC Device” and select “Update Driver Software”.
3. Select “Browse my computer for driver software”.
4. Select “Let me pick from a list of drivers on my computer”.
5. Click on the option “Have Disk”
6. Click on “Browse” button and locate the INF file that I have attached to this response.
7. Accept any Windows’ message.
8. Now you can change the port number by clicking on “Freescale CDC Device” --> “Proprieties” --> “Port Settings” --> “Advanced” --> “COM Port Number”.
9. Finally, accept changing the port number.

You can use the USB2SER with this driver, but it doesn’t support Hardware Flow Control. If you want to have the USB2SER device with all of its features, you need to repeat all the procedure, but now, selecting the INF file included on USB2SER installation folder, located at the following path:

C:\Program Files\Freescale\USB2SER\USB2SER_Drivers\FSL_USB_PID.inf

USB2SER developers are aware of this issue, and they are working on an updated driver for fixing it. Please let me know if you still having troubles or if you have further questions. Have a nice day.

*** NOTE: Please change the extension of usb2ser.info file for usb2ser.inf ***

Hope this information will be useful for you.

Have a good day.

David Diaz
