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.

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.

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

BuildID 20130718070206
Version 18.1

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