This is less of a question and more of a comment in case someone else finds it helpful..
But if like me you've modified the usb_desc.h file to change the name of a device or you've changed something in the usb.desc.c file, but Windows isn't reflecting the changes because it 'remembers' the device, here are a few pointers to help Windows forget. If you encounter this situation I'd recommend disconnecting the device and following all of the steps below for the belt and braces approach. Changing the devices' VID and/or PID/BCD also let's Windows think the USB device is 'new', but that workaround has its own pros and cons.
1) Use the USBDeview tool to remove the device(s) in question.
This handy little tool lets you view all the USB devices that are and have been connected to your Windows device and allows you to uninstall them. It's freeware and runs as a standalone utility, no install required.

2) Remove the relevant device(s) from Windows Device Manager.
Even when a device is no longer conencted to your computer it will remain in Device Manager as a hidden device. Select the View menu tab and enable Show hidden devices to reveal those devices that Windows still thinks are there.
3) Windows Registry will also remember your device. Browse to the following registry key and delete the appropriate keys as necessary: HKEY_CURRENT_USER\System\CurrentControlSet\Control\MediaProperties
Look for anything that contains the vendor ID used by Teensy, which in this case is 16C0. Sometimes it's worth searching the entire registry hive for VID_16C0 to find any other traces that are hidden away.
**Always apply caution when modifying the registry as deleting or modifying the wrong thing can have negative consequences. You make registry changes at your own risk**
And finally.. I've also had issues where the Arduino IDE is caching certain core / library files when compiling, and thereby not reflecting the recent changes that I've made. In some instances I had to workaround this issue by clearing Arduino's cache. Launching the Arduino IDE application using the '--clean' switch seemed to work for me, emptying the Temp folder in the user's profile folder seems to help too.
To run the Arduino IDE with the '--clean' switch you can open a command prompt and navigate to your Arduino IDE install folder, this will typically be one of the following:
C:\Program Files\Arduino IDE\
C:\Program Files(x86)\Arduino IDE\
or
C:\Users\username\AppData\Local\Programs\Arduino IDE\
Then run the command:
"Arduino IDE" --clean
the quotation marks are required as the .exe file contains a space in its name
The Temp folder can be found here:
C:\Users\username\AppData\Local\Temp\
Note that if you empty this, be sure to only delete the contents and not the folder itself, you will no doubt encounter files that cannot be deleted because they are currently open, just skip these **Again, you do this at your own risk**
