Teensy Joystick Enumeration?

[adamwolf]

Hi folks,

I have a few museum exhibits in place that use a Teensy 3.0. I programmed them with Teensyduino 1.16. I create a USB joystick, and I'm running into what appears to be a regression when using Teensyduino 1.17 and 1.18. (I haven't been able to try 1.19 yet.)

The issue I am encountering appears to happen even with the built-in examples.

Using Teensyduino 1.16, the joystick enumerates as /dev/input/js0 on a multitude of Ubuntu machines, even fresh installs. Using newer versions than that, namely anything that supports the 3.1, it enumerates as /dev/input/js1.

Does this happen to other people? I've been using 3.0s in the meantime for new installations, but I'd like to get this figured out. Is this something where I can copy the USB descriptors from 1.16 to the newer versions? A client physically broke a board, and all I have on hand are 3.1s--so figuring this out saves me a pretty penny in overnight shipping fees for 3.0s!

Thanks folks!

As a quick fix, you can get the old versions by simply editing the download URL. Just copy the link (eg, in Firefox, right click and copy location) and change the 3 digit version number, then paste it into the address bar to start the download.

Thanks Paul! The problem is that it doesn't appear that any versions that support the 3.1 have the "old" joystick behavior that I'm looking for. I saw another thread has a pre-release 1.20, and I may try that.

I also realize that this probably doesn't matter for many users, but unfortunately it matters to Blender.

Can you give me anything more to do on, other than Linux creates /dev/input/js0 vs /dev/input/js1 ?

If the device name created by the kernel+udev is really the only problem, can it be solved by a symbolic link or udev rule?

I'm not on site with the device at the moment. I believe it is enumerating two joysticks, but the first one doesn't have any axes or buttons. I was hoping this was something known. I can post more details in a day or two.

Hi,
I have the same problem as Adam.
I have a Teensy 3.1, I use Teensyduino 1.24 with Arduino 1.6.5.
When I try the Basic USB Joystick Example, Linux sees two joysticks.
Teensyduino Serial/Keyboard/Mouse/Joystick (/dev/input/js0) has 8 buttons
and 2 axes stuck at (-32767,-32767).
Teensyduino Serial/Keyboard/Mouse/Joystick (/dev/input/js1) is the good one.
I'm using Kubuntu 14.04 (Kernel 3.16).

I tried Hamaluik's custom joystick (http://hamaluik.com/posts/making-a-custom-teensy3-hid-joystick/)
and only one joystick is seen, unfortunately the axis are not working very well, and I prefer use default joystick.

Thank you for your help!
