I don't (yet) have a Mx series Macbook, my 2017 14,2 is intel. I did
locate a tidbit a while back out the USB-C ports being a bit glitchy
when switching modes: Thunderbolt 3/4 to USB 2/3, and also the
touchbar. I have this snippet in /etc/rc.d/rc.local to trigger a reset
of usbmuxd:
# Reset macbook usb
echo "1-3" > /sys/bus/usb/drivers/usb/unbind
echo "1-3" > /sys/bus/usb/drivers/usb/bind
USB connection still gets confused (some USB 3 only show up as USB 2),
but plugging in is better and the touchbar lights up correctly.
Kernel 6.18.2
Interestingly enough, once I found the "right" USB-C cable (we don't
need no stinkin' STANDARDS!), the USB-C KVM built into my Gigabyte 1440p
monitor works to use the that external display and with Razer
keyboard/mouse.
