Crash when starting app on OS X Lion when enumerating HID devices

[Kamil Figiela]

App just after the main window shows up. Backtrace says it is problem with HID devices. I attached full crash log from os x with backtrace, hardware spec etc.

Regarding my HID devices:
 - MacBook keyboard & trackpad
 - Bluetooth Apple Keyboard and Trackpad (not connected at the moment)
 - USB Soundcard with two buttons (not connected at the moment)

I tried connecting those devices and nothing changes.

I forgot to mention the fact that Mixxx was working perfectly just two days ago (the same version). I cleared configuration (file in ~/Library/Preferences and ~/Library/Application Support/Mixx) and did reboot OS X and problem persists.

I found project https://github.com/signal11/hidapi and created additional attachment from the output of hidtest program. They probably had similar issue https://github.com/signal11/hidapi/issues/26 with this API.

Same issue here with OSX 10.6.8 and Mixxx 1.11beta1.
Just got a new graphic tablet cause my old one died, and if it is connected Mixxx crashes on startup.

This bug is somehow non deterministic, today I tried to start Mixxx beta and it works fine.

[RJ Skerry-Ryan (rryan)]

Jus -- can you try a more recent 1.11 build? I think I fixed this in
lp:mixxx/1.11 r3291

Tried with fresh 1.11.0-beta2-pre bzr r3297 installation which crashed too.
Note: Compiled with "scons shoutcast=0" , probably wont matter but who knows (shoutcast=1 wont compile since months).

If i disconnect the device, Mixxx starts with no prob.

[RJ Skerry-Ryan (rryan)]

Thanks -- I suspect this is an issue with hidapi because it looks like it crashes on a simple call to hid_enumerate.

Could you try building hidapi's 'hidtest' program and seeing if that crashes?

Try this:
git clone git://github.com/signal11/hidapi.git
cd hidapi/mac
make
./hidtest

Does not crash with the device connected

Since this is fixed in hidapi but not yet part of a release I've put together a pre-release of hidapi 0.8.0 and imported that into our tracker. It includes every commit up through commit a22320f76d66db269cbb3e709a23231990bc9b69. https://github.com/signal11/hidapi/commit/a22320f76d66db269cbb3e709a23231990bc9b69

Could you please give lp:mixxx/1.11 r3410 a try?
Builds should show up here shortly: http://builds.mixxx.org/builds/release-1.11.x/r3410/

[RJ Skerry-Ryan (rryan)]

Tentatively marking this fixed since I haven't heard anything back from Kamil.

Thanks for the report!
