Hi waterzhou

I am working on i.MX 6 SoloX SABRE SD board to support a customer for 3G USB dongle for data connection.

The changes that you mentioned above are related to the PCIe interface.

Will the above changes also support/ applicable to  3G USB dongle?

How do we interface the 3G USB dongle with the PCIe Interface?

Thanks and Regards,
