18F4550 & SPI

is it possible to use 18f4550 with spi and usb. Because spi and usb using the same pins(c3,c4,c5). Or it is possible to use these 2 communication from different pins.

Look again at the pins.
The clock, and date in pins for SPI on the 4550, moves from the normal pins, up onto portB. There is a problem with standard asynchronous serial (the RX pin shares with SDO), but no problem with SPI/USB.

Best Wishes
