Actually there is an IC name
PIC18F4550 which has 1 USB port.similarily i want uc with 2 USB ports can u suggest anything?

PIC18F4550 is a 8bit microcontroller.

The port on the PIC18F4550 is a "device"', you need a host port.
The Microchip site has a good search engine for finding a micro with the functions you need.
You need HOST or OTG usb ports.
