Need to connect VUSB to Teensy?

[Davidelvig]

I am hoping I was misguided in the past.

I currently have this schematic routing a Teensy 4.1 to my own board.
I cut the VUSB to VIN connection on the Teensy before mounting to my board.

As I look again, I don't think I need to connect VUSB between the USB C jack and the Teensy.

Since all Teensy power comes through VIN (either from LIPO Battery or USB power coming through my on-off circuit), I can skip that extra direct connection between USBC's VUSB to Teensy's VUSB.

Am I correct? Was this obvious? (I'm OK if you say yes).
As I am powering the Teensy through VIN, I can ignore Teensy's VUSB, right?

And if ignoring Teensy's VUSB (and not powering through the Teensy's USB Micro port) I don't even need to cut the VUSB-VIN trace. Right?

Thanks

Yes. The only purpose of connecting power to VUSB is to power VIN.

And if ignoring Teensy's VUSB (and not powering through the Teensy's USB Micro port) I don't even need to cut the VUSB-VIN trace. Right?

Sure, if you leave VUSB floating... and are positive nobody will ever plug something else into Teensy's USB port.
