demo code for usb

[zartronic]

Hello
I use a demo card with STC8H8K64U ( the black card ), with a 22.1184Mhz quartz.
I compile usb_hid or usb_keyboard with sdcc 4.3.0.
What is the correct configuration for the CLK to give for compilation?
because for the moment it gives an error when connecting.
Unknown USB device (device descriptor request failed)
USB\VID_0000&PID_0002\6&38b0fa34&0&3 has been configured.
Did you run these examples connected on Windows?
Good day
