I was trying to find how to do this with the smallest total length.  Using these I have a 32GB micro-usb thumbdrive that sticks out exactly two inches in length and costs ~$22.

Frank,

I bought something very similar to your adapter for a very similar price, but it does not seem to work. (MY Nexus 7 is unlocked and rooted).  I have an OTG cable that works fine.  I do not know if an OTG adapter is a "crossed" adapter and what I bought was a straight adapter.  Any ideas? Anyone?

Thank you.

Hi Everybody,

I take back what I reported in my post earlier.  About a couple of hours ago,  I posted my previous note,  I went back to try it one more time on The Open Garden. When I tried it this time,  both my phone and my tablet showed that they each were connected to the internet and also each other. At that point,  I disconnected the WiFi from my tablet.  The graphic then showed that my tablet was connected to the phone which in turn was connected to the internet.  Right now I am posting this note from my Nexus 7 tablet which is connected to the internet through the bluetooth to my phone which is connected to the internet through WiFi. The next stop is to are if I can concert through 3G or 4G connection.  Will keep you posted.

Regards,

I have a Razr Maxx on Verizon and Nexus 7. Though FoxFi shows it is working (that is, on the Razr Maxx, Hotspot is on.  On the Nexus 7, FoxFi Wifi shows it is connected.  But none of the browsers, Chrome, Google, Opera Mini and Opera Mobile, seem to work.  I thought I read in some blog FoxFi does not work with JellyBean, but you all seem to say it works.  Any help to help understand this will be appreciated.

Thank you.
