Not sure whether to block on this; although I can reproduce this consistently on a few different Macs.

It also repros on a build more recent than that for leorun4 - I am seeing the issue as well on today's Comm RIL build:

I tried to reproduce this symptom, but my device is working fine.
If you have any logs about UMS hang, plz share it.

Comment 3

[John Hammink]

I'm able to reproduce this consistently.  What sort of logs do you want?  it's not possible to get them off of my hanging computer, so therein lies the problem.

Comment 4

[leo.bugzilla.fw]

I'm still can't reproduce it.
I need kernel and main logs. Could you pull the logs using other PC?

Is there any specific reproducing step? 
How frequently occurs this problem?

I will test this on other versions of Mac - John is seeing this on 10.7.5.

Comment 6

[Marcia Knous [:marcia]]

Using 10.8.5, not able to reproduce this on Leo using:

Gecko  http://hg.mozilla.org/releases/mozilla-b2g18/rev/7f6f4bc1a621
Gaia   f1d2e3fd806dc55f167c72ac8ef7a3b6baed915e
BuildID 20130718070206
Version 18.1

Will try 10.6.8 as well as another Leo device just to make sure.

Comment 7

[Marcia Knous [:marcia]]

No issues testing with 10.6.8 IMac using the same build ID in Comment 6. I also tested with a different Leo device that just has the base image from 6-20 and that device also connected fine.

Small slice of our userbase, and not easily reproducible.
