For full-speed operation, the clock source must be 48 MHz. Even so, the microcontroller core and other peripherals are not required to run at that clock speed or even from the same clock source. Available clocking options are described in detail in Section 2.3 “Oscillator Settings for USB”. 17.9 USB Firmware and Drivers Microchip provides a number of application specific resources, such as USB firmware and driver support. Refer to www.microchip.com for the latest firmware and driver support.
