Hi Paul,
First of all, thanks for these great boards you developed, I bought two 4.0's and I enjoy very much the MIDI functionality on them (using latest 1.49 beta 3) !
Context:
Enthusiastic I developed a bunch of new PCB's, that accept an external big USB-B connector, more adequate for a fairly large midi to usb interface (see pic below)
(the pic does not show the wiring between the teensy and the MIDI motherboard but of course they are connected there as my design provides all four 5V GND D+ and D- signals to the USB-B connector, i have then to solder D+ and D- to the Teensy pads at the end of the build)
Problem:
A. On the Teensy 3.2 boards I also tested with; it worked as expected with my PCB:
i could connect my new midi interface pcb to its big external USB B connector and use it for both programming and MIDI -> no problem.
B. Now with both of my new Teensy 4.0 boards (that I bought from your site directly), it does NOT work with the USB-B big connector,
and after investigating, found out that D+ and D- are not connected to the micro usb connector pins (checked with my multimeter several times and both signals are not connected.
Am I missing something?
I hope I dont need to unsolder the micro USB connector to use a bigger USB B connector ?
