Comment 596 for bug 88746

I'm seeing the same thing in 13.04 w/ Samsung Galaxy Note. It used to work fine, but after upgrading from 12.10->13.04 and from ICS->JB, this device is unusable from Ubuntu. Dual boot to Windows and it works fine.

Attached file is log from plugging device in for just a moment. If I leave it connected, I will get a never-ending stream of popups that look like "Unable to open MTP device '[usb:003,021]'" with 021 rotating between all numbers up to 127 and then starting over. I believe that is caused by the constant flow of:
