Hi,

If you use USB HID connection, there is no need for FTDI drivers.
Do you use USB HID or USB UART connection ?

I use USB HID.I mean functions HID_Enable,HID_Disable,HID_Read,HID_Interupt...

One question.
When I conect 2nd USB cable in my easypic should windows recognize PIC 18f4550?

Hi,

You won't be able to see the 18F4550.

One USB cable is for programming, the Windows will detect the development board/programmer via this cable.
The other USB cable is for USB HID communication between the 18F4550 and PC, you should use USB HID termnal to establish this communication
and of course load/program the USB HID example given in the compiler.
