USB PCDC Stops working

Hi everyone,


I am working on customized board with Rx64M core controller.

Also, I am using FIT modules i.e. r_ether_rx FIT module for Ethernet and r_usb_basic, r_usb_pcdc for USB as driver code.

USB communication stops after some time.

This problem occurs comparatively fast when Ethernet communication is also present.

Anybody have faced similar problem?

Please provide any suggestions...
