Teensy 4.0 command line loader

[amensch]

This is more of a linux question wrt. the Teensy command line loader. Using the 4.0, and we've recompiled to loader for a Tordex Colibri environment. Had it working great for 3.2. Now, getting this...
root@[111902180103]:~#teensy_loader_cli -mmcu=TEENSY40 -s -v -w Blink.ino.hex
Teensy Loader, Command Line, Version 2.1
Read "Blink.ino.hex": 13364 bytes, 0.7% usage
Unable to soft reboot with USB error: Success
Waiting for Teensy device...
(hint: press the reset button)
// Must hit the reset button
Found HalfKay Bootloader

Booting


The active code in 49-teensy.rules looks like this:
ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789B]?", ENV{ID_MM_DEVICE_IGNORE}="1", ENV{ID_MM_PORT_IGNORE}="1"
ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789A]?", ENV{MTP_NO_PROBE}="1"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789ABCD]?", MODE:="0666", SYMLINK+="teensy%n"
KERNEL=="ttyACM*", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789B]?", MODE:="0666", SYMLINK+="teensy%n"


lsusb produces:

I poked around here https://www.pjrc.com/teensy/check_halfkay_linux.html
and here https://www.pjrc.com/teensy/loader_cli.html

and am surely missing something. Please, any ideas? Things to check?
Thank You,
John

I don't understand the question. Everything you've described looks like it's working properly.

Sorry Paul, That's what's got me. I'm not sure where the problem is, all looks good. Right up till the loader stops and asks you to hit the Teensy button.
I guess I need to dig into just what 49-teensy.rules does and go from there. Get out the linux bible.
Thanks, and keep going. These T4.0's are great, and I'm looking forward to playing with a 4.1 before too long!
Regaards,
John
