FX100 cannot detect device

Hi all

I have a question.
The device is ready. After I plug usb converter to PC, I get a COM port.
I expect to see some Q2686 modem devices with question mark, but nothing happened.
If anyone could tell me why, and how to solve it.
Thank you all.


FX100 does not have a Q2686/7 internally, it has a Q2698 which is a different chipset and hence different USB drivers. You need to install the ones below.
