Can my Teensy 3.5 come back to life?

[laptophead]

I unplugged the USB in the middle of a long sketch upload. I had to.
The teensy is running a robot arm and it went berserk...

After recovery, the Teensy USB port is not even seen on my Mac

On windows, it says "invalid divice descriptor" in Device manager.

What to do>?

Please help

Unplug the Teensy from USB
load a simple Blink sketch in the IDE
In the IDE do a Verify Build
While HOLDING the Button on the Teensy connect the USB and hold the button another second
Release the button and it should have the Teensy arrive in HID Bootloader mode and be programmed if the TeensyLoader program is in Auto Mode.
If not Click the Upload and Reset icons on the TeensyLoader - or put it back into Auto mode

If that doesn't work do a 15 second restore:
> start a timer with usable seconds.
> Connect the Teensy to USB and hold the Button for 15 seconds and release it
> Then repeat the above steps for the Blink sketch.

Yes, that worked easily

Thanks a lot
