slow polling rate coming from arduino due native usb port

[clock]

I have a mouse plugged into the native usb of a arduino due, then sending the inputs to a teensy. my issue is that i only get 100 polling rate from this.

i know the teensy is not a problem (i made a small script that made it move in a circle and tested, it got 500 polling rate with the INTERVAL in teensy header set to 2)

i should be sending information fast enough since im converting everything into bytes (i.e mouse position, buttons, etc)

using rx and tx pins to communicate between each other.
