    Hi Vivek,

    I'm sorry, adding a USB modem is a system level issue and beyond the scope of the support that TI provides on these forums. If you come up with specific information that USB is not working correctly, we will be glad to help you debug that. I would think your modem provider would provide the support for adding their product to a Linux system. The AM335x should not be any different for these purposes.

    Thank you.
