Hello All,
On the STM32U575 is there any guidance regarding use of external resistors? I don't see any on the reference design so I didn't put it on my board either. USB data rates are fairly slow, is impedance matching even required?
We are using TinyUSB so that we can avoid the RTOS and it works fine mostly, but occasional USB disconnects.
We discovered by accident using a longer cable seems to resolve this. I am wondering if it is a fluke or if there is some rational reason for this.
Thanks!
