The bootloader source code is usually not exposed to customers. However, please wait for the confirmation on the Tech Support Case you created.

I also need the bootloader source code ,because I wanna know how to reset the 8051 CPU and run code from the start, CPUCS.0 is not writeable. can you help me? plz!!!
Yes, the CPUCS.0 bit can not be written by the FX2LP firmware. However the host can reset the CPU by sending an 0xA0 vendor command with 0xE600 as value and 01H as data. To bring the CPU out of reset send 00H as data.
However we do not expose the bootloader source to our Customers.
Thanks, it can reset the CPU by host with using 0xA0 cmd, and ezusb reloads firmware from EEPROM and do ReNumeration ; but I also need to reset CPU by firmware itself, I mean that firmware can write a register to make ezusb to reset CPU , reload firmware from EEPROM and do ReNumeration .
