Use of PINS C6&C7 as output in PIC184550 + USB Enabled |

Does anyone know if I can use the two mentioned pins(C6 and C7) in PIC18F4550 as output with USB function enabled? I have tested it with a single output_toggle function, but it did not work..... I know that C4 and C5 cannot be used as Input when USB active, but what about 6&7? Any help would be appreciated!

Example of a short, complete test program for 18F4550:

Also post your CCS compiler version if you know it. |

...according to the datasheet, table 1-2, both C6 and C7 can be used for digital I/O but have ST not TTL buffers.
we'd have to see your code to figure out what you're doing wrong....

Obvious things would be either the UART is enabled, or SPI.
