hi, in my project we are using virtual com port for a communication between pc(usb) and stm32f103(USB). But due to ground loop and noise we are facing communication problems. so, to over come this we are planning for communication between pc(RJ45) and stm32f103(USB). i am new for this, please any one suggest me about this.

To connect the USB device on STM32F103 to PC Ethernet port, you'll need a ''system'' which has USB host and Ethernet port, such as Raspberry Pi or Beagle Bone, not just a dongle.

I recommend you USB isolator instead, such as ADM3160, to cut out the ground loop.
