Re: Issues 179505
Heh. yes. I'm just saying. As someone who has hacked on this stuff a bit and watched a lot of people hack on it, if their projects didn't work in freebsd/pcbsd, they'd say "fuck it" and reinstall Linux. If you'd like to further adoption of this stuff on FreeBSD, we have to work around the brokenness. :( Adrian On 21 June 2013 17:34, Mike Meyer wrote: > On Fri, Jun 21, 2013 at 4:08 PM, Adrian Chadd wrote: >> On 21 June 2013 14:07, Hans Petter Selasky wrote: >>> I think I have one of these devices at work.

Did you mean "OSX" instead of FreeBSD there? While not really optimal, I'd consider it acceptable if the fix were in software, so that the Arduino IDE's "burn bootloader" menu entry could be used to fix the thing. But fixing things so it just worked would be better. Thanks, http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"

Considering there's a large number of unfixed Arduinos out there and it works fine on Linux, Windows and FreeBSD, I don't think "fix the arduino" should be the only solution.

Sorry 'bout the extra emphasis there.
Anyway, the problem is not *simply* the sketch code. It could be
something in the Arduino bootloader violating a USB spec that Linux
doesn't care about and FreeBSD does. But mucking about with the user
code on the Arudino (i.e. - sketches) doesn't change anything: I get
the same behavior whether it's running a trivial Blink demo (pretty
much no libraries used at all) or a complete interactive shell:
It works as expected when connected to Linux running on a VBox VM,
with the umodem device always being present.
If I don't connect it to the VM, the umodem device appears when the
board is plugged in or reset, then disappears before the sketch starts
running.

I just tried BitLashDemo, which uses the umodem connection to provide
an interactive shell on the Arduino. Except it won't work on the
leonardo talking to FreeBSD, because it disconnects.
The sketch shouldn't matter. If I connect it to Linux running on a
VBox VM on FreeBSD, everything works as expected, no matter what
sketch is running.
I've updated the issue to note this.

Ok, it seems like there is a bug / misfeature in SoftSerial on the Leo:

What code ("sketch") are you running on the Leonardo?
According to thise page: http://arduino.cc/en/Guide/ArduinoLeonardo
the board only has one mikrocontroller, so unless your program ("sketch") on
the Leo
handles the usb communication, there will be none after the board resets.
