“I am a new owner of the Nexus 7 and when I connected it to the USB port
of my desktop computer for the fi rst time everything was fi ne, but on a
second attempt (the next day) I could not get connected. I found a message
today (in Computer) that an “unknown device” was connected. The leads
are OK. Is my Nexus 7 faulty?
This seems to be a common problem, but
there is some hope because there are a
number of things you can try. Firstly, we
would advise to download Android File Transfer
from http://www.android.com/fi letransfer and see
if that lets your computer see the Nexus.
In our
experience, many PCs will be able to see a
device using this software even when the
standard fi le manager cannot. If that does not
help, check to see if USB debugging has been
enabled accidentally in Settings.
If it has, disable it
for the moment. In Settings>Storage look for the
button in the upper-right and make sure that MTP is
checked. If neither of these work, try going to http://
bit.ly/xvSSl and downloading and installing the
offi cial Google USB driver.
It sounds as though some
settings have changed on the PC as it worked
initially and then failed, but we remain sceptical
purely because this problem is not uncommon on a
Nexus 7.
If you are brave, some people have actually
made their own drivers to resolve connection
problems like this, and a quick search on the net will
highlight which are available.
You will of course
need to carefully consider what to install if it’s
coming from an unoffi cial source. Good luck getting
your Nexus connected.
