If anyone can help me with this issue - please help :) Im looking also LAN driver for win7

Do you understand that only Windows 10 is supported by the SOC type CPU in this board? That is why you will only find drivers for Windows 10 on this board's download page.

The reason the USB ports do not work is because ALL of the USB ports will only use a USB 3.0 driver. That is a requirement from Intel, and is the same for all of their newer chipset and SOC systems. Windows 7 does not have a USB 3.0 driver built into the Windows 7 installer. You must install a USB 3.0 driver yourself.

I believe the USB 3.0 driver in the link below will work with your J3455 system. But did you try to run the INF driver ver:10.1.1.34 from your board's download page? This driver might not install if it cannot recognize the hardware it is working with:

For the Realtek RTL8111GR LAN chip, you can try the Windows 7 driver download on this page.
