Hi Imed,
if you choose
<subsystem name="telemetry" type="transparent_usb"/>
as described the peripheral clock is increased automatically (30MHz instead of 15MHz). You can do that manually by setting USE_USB_HIGH_PCLK.
The warnings are from the USB stack - they should not harm. Would be great if you could fix them.
