MTP over USB not working on I8190

[jankantert]

In CM12 (Build 12-2015311-UNOFFICIAL-golden) MTP is not working properly. When I connect the phone to my PC (tried Ubuntu 14.04 and Windows 7) the device will not show any data partitions. Adb is also not working fully, so this may be also USB related:

$ adb devices 
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached 
xxxxxxxxxxxxxx  offline

Additionally, when I open Settings -> Storage -> USB Connection and click on PTP or MTP the settings dialog crashes.

Same here but with Mint 16.
and sometimes in adb devices it say unauthorized, but no confirmation dialog!
adb over wifi not working either, so i guess it is not an usb driver problem.
adb can connect but not authorized over wifi!

Still no luck with build 12-20150205-UNOFFICIAL-golden

here is the logcat when settings crash on changing usb connection, but i cannot see anything useful:

Fixed in current release (build 12-20150209-UNOFFICIAL-golden). Thanks!

[valduze]

Where can I get the source of this ROM so that I can compile it my self and fix the incoming call crashing problem or please fix it

No related to bug. But I would start here: https://github.com/NovaFusion/android_device_samsung_golden/tree/cm-12.0. Fork and create a Pull Request when succeeded.
