Warning: USB Module Is Designed To Function At Bus Clock Frequency = 24 MHz

Hello, First of all, I am so new to the Microcontollers' designs and using tools for te purpose of designing them. So be patient with me. Right now I am using CodeWarrier 6.1 to write a code for MC9S08JM60 in Processor Expert mode. I get the above warning message even if all the CPU and USB settings are in default values(i.e.without touching any settings). I tried to change the bus frequency, but I get out of range error. Here is the related settings on the CPU:

High Speed Mode: 

  • High speed clock: Internal Clock
  • Bus frequency divider: Auto Select
  • Internal Bus Clock: 16.0 MHz
  • Fixed frequency clock: 0.015625 MHz                                                           

It is truly appreciated if someone help me to know what I am doing wrong and how to fix the problem. Also, the project is attached for your reference.
