Restart U2C when klipper restart

[bugalaws]

I have a trouble, when my print end it powering off the main board(mks robin nano) and the sb2209 by canbus .. ao the raspberry stay on.. then i powering on the printer i only can connect again at the sb2209 if i plugin off the u2c usb cable e pluggin again …

my question is: ther some way to restart usb by klipper because is so hard every time i acess the back the printer to unplug/plug the usb cable from the u2c….

i can run a script on the raspberry host to restart the usb port, but i cant run the scrip when klipper is powering on…

I have this issue with BTT U2C. Whenever I powercycle the printer (rpi is powered separately via official power adapter), I have to do usbreset xxxx:xxx to reset the U2C (instead of unplugging and plugging back in). Any idea how to solve it ?
