Teensy 3.1 is not recognized under Mac OS X - Yosemite (10.10)

[bpoultier]

Hi All,

Since I've updated my laptop under OS X - Yosemite, my Teensy is not longer recognized.
If you don't want to loose some time ;-)

Does any USB device appear in the system profiler when you plug in Teensy?

[bpoultier]

Hi,

No Teensy appears as you can see. I've tried with my second Teensy but it's the same: nothing
I've also change the cable to see if something change but no.

Sorry this screen shot is in french.

Can your mac see it if you plug Teensy into a USB hub, and then plug the hub into your Mac?

[MuShoo]

I'll pipe up and ask if you've hit command-R to refresh the system report after plugging the teensy in? If you had system report open before plugging it in, I don't think it'll recognize it until you refresh the list.

I too am having this problem in Yosemite. Just installed the FTDI drivers just to be sure. I don't see my Teensy 3.1 in the serial devices list on Arduino or ls /dev/tty.* but when I compile/upload in Arduino, the Teensy Loader app somehow magically makes it appear as a serial device until I unplug/replug it.

Paul, any ideas?

IOUSBFamily doesn't like it when I plug in. I get this in the console:

After Teensy Loader does it's thing, this gets printed in Console:

Any update to this, i'm hitting the same issue here :/

Hi Paul and the team,

I have a few Teensy 3.1 that I'm playing with and I've spotted a pattern.
The "older" board that I've been using to develop my code with reports in "System Report" as a s"USB Serial" ... notice that the Product ID is 0x0483


The "newer" ones that I have are reporting as "Teensy RawHID" and the Product ID of these are all 0x0486:


After going through the rest of the boards to confirm this, I've also found a DoA board - Paul any chance you could help out?

But more pressing, is there a set of steps to be able to get the 0486 mod'd boards to come up as a serial port ?

Thanks,

Anthony

[BlackInk]

Ok, some more poking and I've made some progress:

1) from the IDE, choose "Tools" -> "USB Type" -> Raw HID

2) Compile and upload the code, the Teensyloader sparks up and loads the code.

3) Again, click "Tools" -> "USB Type" -> "Serial"

4) Then "Tools" -> "Serial Port" and the Teensy should be there ready for use.

So far so good (apart from the DoA unit)

-Anthony

[BlackInk]

Oh yes: the product ID is back to 0x0483...

[PaulStoffregen]

Yes, that's what it's supposed to do. The Product ID changes, depending on which option to choose in Tools > USB Type. Of course, it only shows up as a serial device after you've programmed it with one of the options with "Serial". The others don't implement Serial, so MacOS won't detect them as serial ports or modems.

Please email me directly about the DOA board, paul at pjrc dot com. Please include a link to this thread in your email, and info about the purchase (eg, order number or other info we can use the look up the order).

I had the same issue. In my case it was a "cheap" flat-band cable.

I then used a seemingly more shielded version and it worked instantly.

So try at least 3 different cables when in doubt.
