The actual objects were not created like they were on the T3.x side, so just copied it over from there.

usb.c did not include the usb_rawhid.h so it would give a compiler warning about having to create a ...

Decided to go ahead and move the TX Buffer there as well
Did a quick check in earlier test program to echo the contents back.

The other test program was already setup to receive data on the HID and does hex dump of buffer which looks correct.  So far so good.

Testing against issues of hang from thread:

Fix comment re: systick

fix EWM address

#define FLASHMEM

be compatible with teensy 4

update macro analogInputToDigitalPin

This answers a long standing question :-)

teensy3: usb_serial: Fix port 2/3 mismatch

The code for the second port was accidentally expanded into

usb_serial2.c.

Teensy3 usb triple serial

shiftout: highest speed 10MHz

Fixed analog comparators IRQ names.

T4.1 - Serial8 is on pins 34 and 35

It was defaulting to the same NUM_DIGITAL_PINS and NUM_ANALOG_INPUTS as the T4.0 so updated for the new pins

There are two pins on the SDCard IO pins that are valid alternate pins for Serial5
Serial5.setRX or setTX.

These pin numbers changed from T4 to T4.1 so update table depending on which board.

Serial8 is now defined for T4.1.

Previously it was defined for T4B1, but went away on T4B2 and released.  It is now defined on the T4.1
