name.c rewrites other Teensy MIDI device name strings???

[oddson]

I just ran the MIDI Name example code (unaltered) from the current beta based on Pauls' reply in this thread:
https://forum.pjrc.com/threads/37022-Change-Core-MIDI-Name

It not only renamed the T3.6 I intended but also the T2.0 that's been hooked up to my computer as a controller for years... even though it doesn't work with directly with T2.x... wazsup?

Probably Windows caching the info in the Window Registry?

 

[oddson]

Yeah... of course it didn't save the name to the board and it's since resolved with reboot.

Does each Teensy have a unique Product ID in the MIDI Adapter Device Descriptor?


edit...I mean each type... not each individual board.

 

[PaulStoffregen]

Yes, each USB type has a unique product ID. You can see the in usb_desc.h.

However, some of the newest types added by 1.30 were not unique. This is fixed in the latest 1.31-beta3. Details are in usb_desc.h.

I just ran the name example on my Kickstarter T3.5 and it worked fine once I reset the USB type in the compiler to MIDI (I had been debugging the program with MIDI + SERIAL previously, and had already manually changed the USB_MIDI+SERIAL entry in usb_desc.h to my desired name)
Might be useful to mention this in the explanation text in name.c, as I suspect some people might start off with MIDI+SERIAL during the development phase of their project.
Thanks for this- its easier than editing usb-desc.h and then remembering to revert to the default usb_desc when starting the next project.

Is it possible to use this method to change the name of another type of usb descriptor ?

Only the ones with weak linker alias can be overridden with this code.
