Is it possible to use a 48MHz (1% accuracy) clock from FLL with the USB device? We tried it and USB device works. A less accurate clock may cause packet loss, is it right?

In PSoC63 TRM USB host needs to be clocked with 48MHz and accuracy 0.25%. The USB device doesn't have a clock section in the TRM.
