I am a long time Teensy user.
Most of my projects are single items on premaproto boards and I need to use USB for debugging, uploads, and general output.
I add a Shottkey Diode between VUSB and VIN (after cutting the trace). In the past I used a 1N5817 (1A vf 0.5 v) But have now switched to a smt PMEG2010AEBF (1A, VF=10-510mv SOD532 package(super tiny)) .
When using SKPang's Tennsy 4.0 Triple Can Board I get no action on any can port. When I directly connect VUSB to VIN everything works. I have tried several 4.0 and see the same result. It doesn't matter which diode I use.
This is the first time I have seen this on one of my projects.
Anyone have any ideas??.
