I think most modern Android phones use MTP instead of emulating a
generic storage device. I've seen this at least with HTC Sensation and
Google Nexus.

In my case, nothing happens when I connect the Galaxy Nexus but
issuing MTP commands somewhat detect the device:

#  mtp-detect
libmtp version: 1.1.0
